    What is your recommendation for stopping a dripping transmission oil leak in a 6 gallon capacity oil sump, on a 1980 model case tractor.

    TX; Jess

    • BlueDevil Pro on May 20, 2013 at 2:21 pm

      The best product for the leak you have described is the BlueDevil Transmission Sealer. You will need to add 24 ounces (1 bottle and a half) based on your fluid capacity. Keep in mind that it may take a day or two before you see full results.

      Feel free to contact us direct at 888-863-0426 with any further questions.

      • Jess on May 20, 2013 at 7:42 pm

        The fluid in these transmissions are hydraulic oil and doubles to supply oil to the 3 point lift. Will this make a difference in the sealer to be used?

        • BlueDevil Pro on May 20, 2013 at 8:32 pm

          Either product would be compatible for your transmission. Please be sure to use 1 ounce of product per quart of capacity.

        Hi, Just i would like to ask you if there is dealer for this product in UAE and if this oil can stop the leak in the differenatial for Ford Edge 2007.

        • BlueDevil Pro on June 30, 2016 at 8:31 am

          Haytham-

          Thank you for asking about your Ford Edge. The BlueDevil Rear Main Sealer, found here on our website: http://store.gobdp.com/rear-main-sealer-00234/ , would seal a leaking differential. You can order the product directly from our website at the link above and we do ship to UAE.

          Thank you!

            My valve cover gaskets and rear main seal are leaking which product should I use



          • BlueDevil Pro on June 12, 2017 at 9:28 am

            Phillip-

            Based on your description, we recommend using the BlueDevil Oil Stop Leak. The Oil Stop Leak is a universal application and would treat both of the leaks you have described. You should expect to see results after about 100-200 miles of driving.

            Thank you!

            Hey there blue devil ??? Does the product 🤔 harden?? How does it seal a leak in my rear dif???? I just put product in there with no oil just one 8oz container…… we’ll see what happens…..I haven’t started truck yet…gonna wait a day or two….see if it stops



          • BlueDevil Pro on June 7, 2021 at 8:58 am

            Grant-

            The BlueDevil Oil Stop Leak does not harden or thicken in anyway. It works by revitalizing & reconditioning rubber seals/gaskets, to get them back to there original shape and there original flexibility. The product would not be taking the place of your differential fluid. You should use one oz. of the product per quart of fluid capacity. You should have your regular differential fluid in the system, leaving just enough room for the recommended amount of the product.

            Thank you!

        I used Blue Devil in my 2001 Toyota Camry, 4 cylinders.It was an 8 oz bottle.Did I put enough or do I need another 8 oz bottle?

        • BlueDevil Pro on December 15, 2017 at 9:03 am

          Betty-

          One 8 ounce bottle of BlueDevil Oil Stop Leak is sufficient to treat your Camry. Keep in mind that it can take 100 – 300 miles of driving before you see full results out of the product.

          • BlueDevil Pro on April 23, 2020 at 1:56 pm

            Gabriel-

            Is it a blue smoke or a white smoke? Is it coming from out of the tail pipe? Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

          2004 saturn, should I put oil in my car. before or after if it leaked some out? Do I need to drive my car immediately after putting blue devil in?

          • BlueDevil Pro on July 31, 2019 at 8:47 am

            Gloria-

            Yes, you would want to top your Saturn off with oil as needed. You do not have to drive immediately after adding BlueDevil. Typically, it will be around 100-200 miles of driving before you start to notice any improvement.

            Thank you!

      • John Brodnax on April 18, 2020 at 8:41 pm

        I mistakenly put head gasket sealer in my crank case what do I need to do thank you

        • BlueDevil Pro on April 20, 2020 at 9:09 am

          John-

          As long as you haven’t run the vehicle after adding it mistakenly into the crank case, you should be able to change the oil and filters, get fresh oil back in the system, and be good to go. If you are unable to do so, you would want to have the vehicle towed to your mechanic to have the oil changed. Do not run the motor until the oil has been changed.

          Thank you!

          I had a small leak from right rear axle seal. Put AT-205 in differential. Now I have a large leak from both sides of axle. I plan to drain differential oil and add Blue DevilToday.Which product Should I use and should I drive it immediately or how long should I let it sit

          • BlueDevil Pro on September 4, 2020 at 9:10 am

            Harold-

            The BlueDevil Oil Stop Leak would be able to seal leaking axle seals. The product is intended for leaks that are seeping or lightly dripping. You will use one oz. of the product per quart of fluid in the system. Typically, you should start to notice results after 100-200 miles of driving. It does not have to be a continuous drive or be driven immediately upon adding the product.

        Unfortunately, we do not manufacture any products that are intended to stop a leak from the Turbo. A hard part repair may be your best option.

      • BlueDevil Pro on November 28, 2018 at 8:59 am

        Lauren-

        Yes, the oil should basically be at capacity when adding the BlueDevil Oil Stop Leak. You should expect to see results after approximately 100-200 miles of driving.

  2. Bill on June 4, 2013 at 4:18 am

    I have an antique 1954 DeSoto Firedome V8 that has an oil drip. I’m not sure where its coming from, most likely the oil pan or rear main seal. If I add a bottle of Red Devil Oil Stop Leak could there be any possible harm to the motor? Will the product coagulate in the oil filter or elsewhere?

    • BlueDevil Pro on June 4, 2013 at 2:12 pm

      There is no chance at the BlueDevil Oil Stop Leak harming your engine in any way. The product does not harden or thicken so you will not have any clogging or restriction of flow. Due to the fact that this is an older vehicle keep in mind that BlueDevil will not work on old cork seals. Not all older vehicles use cork but if this one does it will not allow the product to work properly.

      • Judy on April 25, 2017 at 2:34 pm

        What is considered an old vehicle? I put Blup DevIL stop oil leak in my 1996 Ford Ranger. Dies it have cork? Also how often should I put the product in?

        • BlueDevil Pro on April 25, 2017 at 3:00 pm

          Judy-

          Thank you for asking about your Ford Ranger. Any vehicle manufactured in the 90’s, would have rubber seals/gaskets, so the BlueDevil Oil Stop Leak would definitely be appropriate to use. Once the product seals, it would be a permanent seal, so you should only need to use the product once.

          Thank you!

        • BlueDevil Pro on January 11, 2017 at 9:35 am

          Once the product seals, it creates a permanent seal, so in no way is it considered temporary. White smoke would indicate water/antifreeze burning, where as a blue smoke would indicate oil burning. Feel free to contact our technical support line at 888-863-0426 with any other questions.

    I have a 2000 Toyota Sienna that has a pretty good rear main seal leak. It leaves a couple half dollar size oil spots on the ground every time I stop. People say that oil stop leak damages other seals in the engine, is there any truth to thos idea? If I use BlueDevil will I need to put more in the car every time I change the oil? Why does BlueDevil work for some cases and not others?

    • BlueDevil Pro on April 9, 2015 at 10:03 am

      Dan-

      We recommend adding 1 bottle of the BlueDevil Rear Main Sealer (http://store.gobdp.com/rear-main-sealer-00234/). The BlueDevil will not damage any seals or components in any way.

      The product only needs to be added one time; it will create a permanent seal. In instances that it does not work it is usually due to the extent of the leak.

          Thank you for asking about your BMW 745li. Based on your description, we recommend using the BlueDevil Oil Stop Leak. As long as you are not losing oil too quickly, you would be a good candidate for the product. You should expect to see results after about 100-200 miles of driving.

          Thank you!

    2006 saturn vue front oil leak coming from behind timing cover. Has new front main seal.cam seals oil pump housing and oil pan resealed with silicone but some seal still leaking. Will rear main seal ne better or the other stop leak blue devil makes. What’s the difference in these two stop leaks?

    • BlueDevil Pro on May 12, 2015 at 11:02 am

      Craig-

      To help you decide which product you may want to use we will give you a brief explanation on what each is intended for.

      The Oil Stop Leak is the universal application and will work for oil pan gasket leaks, rear main seal leaks, valve cover leaks, etc. Whereas the Rear Main Sealer is specifically formulated for the rear main seal. If you are not sure where the vehicle is leaking or it seems that there are multiple leaks I would recommend using the BlueDevil Oil Stop Leak.

      Feel free to contact us at 888-863-0426 with any questions.

      Thank You!

    • BlueDevil Pro on May 14, 2015 at 11:30 am

      Shirley-

      The BlueDevil Oil Stop Leak is compatible to use in your Audi A6. We have had experience in successfully sealing leaks in Audi’s in the past. The seal BlueDevil creates is a permanent seal. You should notice results after about 100 miles of driving.

      Thank You!

    Hi I have a 03 Chevy s10 zr2 I have to top off oil in between oil changes I don’t know if it’s burning oil or slowly leaking somewhere can I still use your blue devil oil stop leak and when I add it to my oil does it go in the regular oil fill compartment and do I have to run my engine for two hours immediately for two hours once applied or not

    • BlueDevil Pro on May 18, 2015 at 9:48 am

      Leo-

      Yes, you may add the BlueDevil Oil Stop Leak right through your oil cap (the same place oil is added). The engine does not need to be run for 2 hours immediately; it can be run on multiple short trips over a few days or a week. Keep in mind that if you do not drive a whole lot, it could take a few days before you see results. In general, you should see some results after about 100 miles of driving.

      Thank You!

    i have a 2000 chrysler sebring convertible w v 6 engine I first tried blue devil rear main sealer and seemed to work without any leaks for two months but now front crank seal is leaking leaving spots all over drive way and blowing back on underside of car. Do you think blue devil oil stop leak would work. Also autozone told me i wouldnt have to lower oil level b4 adding rear main sealant .I called cust help line they say lower oil level before using your bottle says nothing about this

    • BlueDevil Pro on July 15, 2015 at 7:00 pm

      Hank,

      Thanks for your question about your Chrysler Sebring. We do recommend BlueDevil Oil Stop Leak (available here: http://store.gobdp.com/oil-stop-leak-49499/) to stop the leak coming from your front crank seals. Make sure you purchase it from our online store or one of our authorized retailers to get our guarantee!

      Also, you do not need to lower your oil level before adding BlueDevil Oil Stop Leak if it is already in the acceptable range. Your car holds 4.5 quarts of oil and BlueDevil Oil Stop Leak is only an 8oz bottle so it will not drastically increase your engine oil level.

  20. james on July 11, 2015 at 11:51 am

    I 2004 audi a6 leaking transmission fluid out. Its the tip 5 trans. Is your trans sealer compatible with my trans and the pentosin atf1 my audi trans uses?

    • BlueDevil Pro on July 15, 2015 at 9:14 am

      James-

      Yes, the BlueDevil Transmission Sealer is compatible with Pentosin ATF1. You should use 1 ounce of BlueDevil per every 1 quart of capacity.

      Thank You!

    • BlueDevil Pro on July 15, 2015 at 8:21 am

      Jordee-

      No, you will simply add the BlueDevil Oil Stop Leak to your engine oil and it works as you drive. Expect to notice results after about 100 miles of driving.

    • BlueDevil Pro on July 17, 2015 at 11:37 am

      Twiggy-

      We recommend adding one 8 ounce bottle of the BlueDevil Oil Stop Leak. The product should be added directly to your engine oil through the cap (same place where oil is introduced). BlueDevil creates a permanent seal. Once the product is added you should notice results after about 100 miles of driving.

      Thank You!

Also, i isolated the leak to the bottom of the cover and it will leak when parked. Do i have to drive it for 2 hours after adding it?

    • BlueDevil Pro on August 4, 2015 at 2:48 pm

      Kevin-

      Yes, we do recommend using the proper amount of the BlueDevil Oil Stop Leak; you only need to add 1 ounce of BlueDevil per every 1 quart of capacity. The BlueDevil Oil Stop Leak is compatible with differential fluid. The vehicle does not need to be driven 2 hours all in one shot; it can be driven on short trips over multiple days. Keep in mind, it may take about 100 miles before you start to see results.

    • BlueDevil Pro on August 5, 2015 at 8:18 am

      Mike-

      Unfortunately, we do not manufacture any products that will work when oil is entering the cooling system. The BlueDevil Head Gasket Sealer is specifically designed to stop coolant loss or to prevent combustion from entering the cooling system. It will work for water/coolant leaking into the oil but not the other way around.

    • BlueDevil Pro on September 21, 2015 at 3:22 pm

      Reginald-

      We recommend adding 1 bottle of the BlueDevil Rear Main Sealer (http://store.gobdp.com/rear-main-sealer-00234/). Once the product is added you can expect to start seeing results after about 100 miles of driving.

      The product can be purchased locally through AutoZone, Advance Auto Parts, O’Reilly Auto, NAPA, and many other auto parts retailers.

    • BlueDevil Pro on September 16, 2015 at 3:56 pm

      Chance-

      Typically, you would start to see results after about 100-200 miles of driving. As long as you’re not losing oil too quickly, you should be able to see some good results from the product.

          It does not have to be a continuous drive. You can drive on short trips over the next week or so; just keep in mind if you do not drive a whole lot it may take a few days before you see full results.

    • BlueDevil Pro on October 22, 2015 at 2:10 pm

      Reggie-

      It usually takes about 100 miles of driving before BlueDevil Oil Stop Leak will start to take effect. You were most likely still losing oil in the first 40 miles because the vehicle does quite have enough miles, with BlueDevil in the system, for it to take effect.

    • BlueDevil Pro on November 2, 2015 at 4:26 pm

      Bryan-

      Thank you for your question. You should start to see results after about 100-200 miles of driving. It does not have to be a continuous drive. You are fine to go 5, 10 mile intervals here and there. It’s just gonna be 100-200 miles before you start to notice results. The product can stay in the system for the life of the oil, no need to change it out immediately after the product has sealed.

      If you have only driven about 100 miles you may not have gotten the full benefit out of the initial application of BlueDevil Oil Stop Leak yet. Continue to drive the car normally for the next week or so and if it still is leaking at that point then call us at 888-863-0426 so that we may assist you.

        • BlueDevil Pro on February 2, 2016 at 10:50 am

          We recommend using 1 bottle of BlueDevil Oil Stop Leak (http://store.gobdp.com/oil-stop-leak-49499/). The product carries a success rate of over 90%; as long as you are not losing a great amount of oil then you should have no problem stopping the leak with BlueDevil. Once the product is added you can expect to start seeing results after about 100 miles of driving.

          BlueDevil Oil Stop Leak will not have any effect on the drivability of the vehicle; it does not harden or thicken to stop the leak but rather recondition & rejuvenate the rubber seals & gaskets within the fluid oil system.

          Thank you!

      Nick-

      The best product to use is BlueDevil Oil Stop Leak (http://store.gobdp.com/oil-stop-leak-49499/). You should add 1 ounce of BlueDevil per every 1 quart of oil; you will most likely only need 2 – 3 ounces for a gear case.

      We currently do not have any distributors in Canada. However, the product can be purchased directly through our website (http://store.gobdp.com/oil-stop-leak-49499/) and shipped to your address in Canada.

      Thank you for asking about your Volkswagen Passat. Unfortunately, it sounds like you may be losing oil a little too quickly for the product. The Oil Stop Leak is intended for leaks that are seeping or dripping out of the system. If you are losing oil like you have described, you would more than likely lose the product before it got a chance to start sealing.

The Oil Stop Leak is intended for leaks that are seeping or lightly dripping from the system.

    1ST OFF,i wanna say that your engine stop leak IS AWESOME! Fixed my leak in just 1 HOUR. I tried Bars stop leak and it was a WASTE of money.

    So i wanted to know since your oil stop leak is so good can i use it on my 1985 Toyota Supra rear end? It uses 75-90 gear oil.

    by the way,this it the one i used… https://gobdp.com/wp-content/uploads/2013/04/49499_OSL.jpg

    Hello!

    We have a transfer case seal leak in our 2007 Chrysler pacifica. We tried 2 bottles of lucaS transmission stop leak, but ut has done nothing. This was almost a month ago. Its dripping on the exhaust causing a bit of smoke from the hood. What would your suggestion be?
    trying to avoid a mechaic…. quote was a few thousand and could climb if rusted parts break taking them off

    • BlueDevil Pro on May 24, 2016 at 11:14 am

      Crystal-

      We recommending adding the proper amount of BlueDevil Oil Stop Leak (http://store.gobdp.com/oil-stop-leak-49499/). You should add 1 ounce of BlueDevil per every 1 quart of capacity; you will not need much for the transfer case due to the small capacity. Once added you can expect to start seeing results after about 100 miles of driving. We have had a lot of success stopping fluid loss coming from transfer cases in the past.

      Thank you!

      • Steve J on March 7, 2017 at 6:23 pm

        Do I added this to the transmission filler tube, the transefer case uses trans fluid. Or is there a separate fill for the transfer case.

        • BlueDevil Pro on March 8, 2017 at 9:09 am

          Steve-

          It would be fine for you to add the BlueDevil Transmission Sealer to your transfer case. You will be using one oz. of the product per quart of fluid in the system. You should expect to see results after about 100-200 miles of driving.

          Thank you!

          -BDP

          • Steve J on March 8, 2017 at 7:58 pm

            should I be looking for a separate filler tube for the transfer case, OR pour it into the trans filler tube. That’s my question



          • BlueDevil Pro on March 10, 2017 at 8:40 am

            Steve-

            Yes, the transfer case should have a separate filler tube so that you can add the product directly.

    Hi,

    I have a Toyota Camry 1999 model and I noticed engine oil leakage a week after I got my oil changed. So I used one bottle of Blue Devil Oil Stop Leak and the leakage reduced to few drops. I am wondering if I need to add another bottle. Will it harm my engine if I add another bottle of Blue Devil Oil Stop Leak. I also heard that I have to run my engine 2 hours continuously. Last time I didn’t do that when I added the Blue Devil Oil Stop leak.

    Thanks!

    • BlueDevil Pro on October 21, 2016 at 9:05 am

      Akash-

      Thank you for asking about your Toyota Camry. It is definitely a good sign that you noticed some kind of improvement. It may just be that the leak you were experiencing was a little larger than what the product is intended for, so the product may have formed a partial seal. Based on your description, we recommend a second application of the BlueDevil Oil Stop Leak. Please contact our technical support line at 888-863-0426 so that we may assist you in obtaining a replacement bottle.
      Typically, you would start to see results after about 100-200 miles of driving. It does not have to be a continuous drive, it would just be around the 100 mile mark before you would start notice improvement.

      Thank you!

    I have an older (but less than 1500 hours) Kubota L35 diesel tractor with loader & B900 Backhoe. There have been numerous minor hydraulic leaks in the past but it just blew one of the lines on a stabilizer. I have the lines to replace all 4 on the stabilizers. It sounds like Blue Devil Oil Sealer would be a good addition after the repairs. Hydraulic system capacity is about 40 quarts – so 40 oz. of BDOS?

    • BlueDevil Pro on October 25, 2016 at 10:42 am

      Russel-

      The more appropriate product to use in your Backhoe would be BlueDevil Hydraulic Stop Leak (http://store.gobdp.com/hydraulic-stop-leak-00238-00239/). Based on the capacity of your hydraulic system you should apply 40 ounces of BlueDevil. The product works well for reconditioning the rubber seals and gaskets throughout the hydraulic system.

  69. caggy on April 1, 2017 at 10:18 am

    I have a 97 Dodge Stratus with a rear main seal leak. Yesterday I bought a bottle of Blue Devil rear main sealer. The instructions say to add it to the engine oil, start the engine and drive the vehicle until the leaks are sealed (up to 2 days drive time). I noticed in a prior comment it was suggested for the person to drive 100 – 200 miles. My question is: If I put the sealer in and only drive it 5 or 10 miles for the first day, and then drive it up to 200 miles over the course of a week or two, will it still be effective enough to work on repairing the seal?

    • BlueDevil Pro on April 3, 2017 at 12:05 pm

    02 ranger 3.0L 110k miles. I recently switched to synthetic and started noticing its burning allot oil. No oil leaks are visible as I meticulously take care of my vehicle. Since I have no leaks, would you still recommend a stop leak or what product would you recommend?

    • BlueDevil Pro on February 23, 2018 at 8:42 am

      Manuel-

      Thank you for asking about your Ford Ranger. Based on your description, if you are not sure where the oil loss is occurring from, we’d recommend using the BlueDevil Oil Stop Leak (https://store.gobdp.com/oil-stop-leak-49499/). The BlueDevil Oil Stop Leak works by revitalizing and reconditioning the rubber seals/gaskets in the fluid oil system. Even if you are not experiencing a leak, the product could be utilized as a preventative maintenance to keep the rubbers from becoming brittle or deteriorating.

      Thank you!

    • BlueDevil Pro on March 23, 2018 at 9:19 am

      Daniel-

      Thank you for asking about your Mercedes Benz W210. It may be feasible in this case to use the BlueDevil Oil Stop Leak (https://store.gobdp.com/oil-stop-leak-49499/) for both leaks you have described. BlueDevil Oil Stop Leak is a universal application and is the more concentrated product, which would treat any of the rubber seals/gaskets in system. You will use one oz. of the product per quart of fluid in the system. Feel free to contact our technical support line at 888-863-0426 with any other questions.

    I had a horrible rear main seal leak on my 1997 Tahoe. It was dumping oil like it was going though a siv. Added a bottle if your product, and 2 days later it has stopped leaking. Just saved me 800 bucks. Can I add a bottle to every oil change?

    • BlueDevil Pro on August 7, 2018 at 8:59 am

      Steven-

      We are glad to hear the product was able to seal the leak on your Chevy Tahoe! Once the product seals, it would be a permanent seal, so you should be good to go at this point. The product does not harden or thicken in anyway, so there would be no adverse effects adding it with every oil change.

      Thank you!

    What are your recommendations to halt seeping hydraulic fluid from the flanges and hoses of a hydraulic pump?

    • BlueDevil Pro on October 25, 2018 at 9:00 am

      Allan-

      The BlueDevil Hydraulic Stop Leak is only intended to treat rubber seals/gaskets. Unfortunately, the product would not be able to help with the seep you have described. Replacing the parts may be your best option.

    I have a 2011 Audi A4 1.8t . My vehicle are using a lot of oil, but theres no visible leaks underneath. However often times when i drive i smell burning oil inside the vehicle which at times are very unpleasant. Can i use Blue Devil oil stop leak?

    • BlueDevil Pro on December 3, 2018 at 9:19 am

      Gray-

      Thank you for asking about your Audi A4. How often are you having to add oil? As long as you are not losing oil too quickly, you would be a good candidate for the BlueDevil Oil Stop Leak. You should expect to start seeing results after approximately 100-200 miles of driving.

      Thank you!

    I used BlueDevil rear main seal stop leak it was a minor leak that developed after I switched to synthetic which I then removed the synthetic and went back to Conventional , But I’m not sure if that is where the leak was coming from, can I add another bottle of the BlueDevil Oil stop leak or will adding two bottles of your product be a bad idea, My engine is a 2006 Chevy 6.0 Vortec with 150,000 miles on it 6 Quart oil capacity

    • BlueDevil Pro on December 27, 2018 at 9:10 am

      Richard-

      Thank you for asking about your Chevy. Based on your description, we recommend adding the BlueDevil Oil Stop Leak. The product does not harden or thicken in anyway, so it would not cause any adverse affects on the engine. If you are due for an oil change within the next 300 miles, we recommend changing the oil first. Otherwise, you would be fine to add the product to your existing oil.

      Thank you!

    I have a 2009 Audi A5 3.2L. Mechanic says that I have a few oil leaks (oil filter housing seal, oil cooler gasket, valve cover gaskets, lower oil pan, etc.) I’ve kept an eye out for the leaks since last oil change and did not receive any oil min warnings. The leaks seem to be seeping/dripping. 1. Will the BD oil stop leak be safe for my car? 2. Can the oil stop leak work for my scenario? 3. If so, how much is recommended for 6.87 qts? Thanks.

    • BlueDevil Pro on January 14, 2019 at 9:00 am

      Tony-

      Yes, the BlueDevil Oil Stop Leak is safe and compatible to use on your Audi A5. The product is intended for leaks that are seeping or lightly dripping, so based on your description, you would be a good candidate for the product. One bottle would be sufficient to treat your vehicle.

      Thank you!

  90. dave Stansbury on February 20, 2019 at 10:32 am

    whats the difference between the ream main sealer and regular stop leak? is either safe to use in a motorcycle with wet clutches?
    i have an old motorcycle 1978 4 stroke twin cylinder wet clutch system. it is weeping slightly on the head gasket between the cylinders. Was wondering if you had a product that you could recommend that would seal the leak without trashing my clutches. Thanks

    • BlueDevil Pro on February 20, 2019 at 11:22 am

      Dave-

      BlueDevil Oil Stop Leak is more concentrated and is the universal application that will work for various leaks such as oil pan leaks, rear main leaks, valve cover gasket leaks, etc. Whereas the Rear Main Sealer is specifically formulated for only a leaking rear main seal. If you are not 100% sure where the vehicle is leaking or there seem to be multiple leaks then we recommend using BlueDevil Oil Stop Leak.
      If it is your head gasket that is leaking oil, unfortunately, we do not manufacture a product for that type of leak. The two products mentioned above are only intended to treat rubber seals/gaskets and our BlueDevil Head Gasket Sealer is only intended for water/coolant leaks. A hard part repair may be your best option.

      Thank you!

    • BlueDevil Pro on May 2, 2019 at 2:15 pm

      Shain-

      We recommend applying BlueDevil Oil Stop Leak to stop the leak. You should apply 1 ounce of BlueDevil per every 1 quart of capacity; more is not better. Expect to start seeing results after approximately 100 miles of driving.

      Thank you!

  93. Chad Millar Jr on May 20, 2019 at 9:17 pm

    I used your product and poured the whole bottle into my engine. Is it safe and normal for my dipstick to be telling me it’s overfilled?

    • BlueDevil Pro on May 21, 2019 at 10:03 am

      Chad-

      If the oil appears overfilled, we would recommend draining enough out to make sure it is at the proper level.

  94. Wes Cameron on November 28, 2019 at 3:11 pm

    Hi, the capacity of my engine is 7.5 liters. Can I add two bottles, or would I have to add just enough of the 2nd bottle to cover the full 7.5 L.
    Thanks. One more question; can this product be used with Pennzoil High Mileage Oil that already has seal conditioners in it?

    • BlueDevil Pro on December 2, 2019 at 9:53 am

      Wes-

      The BlueDevil Oil Stop Leak is safe and compatible to use with Pennzoil high mileage oil. You would need a little more than one bottle for a 7.5L capacity. It is not one of those things where more of the product would be better. You really only want to use the recommended amount.

      Thank you!

    • BlueDevil Pro on May 7, 2020 at 9:31 am

      Michael-

      Thank you for asking about your BMW 335ix. The BlueDevil Oil Stop Leak would only have an affect on rubber seals/gaskets. Unfortunately, we do not manufacture a product for a plastic valve cover gasket.

    What’s the difference between the oil stop and the rear main seal stop? My leak is right where the two meet up.

      Tim-

      BlueDevil Oil Stop Leak is more concentrated and is the universal application that will work for various leaks such as oil pan leaks, rear main leaks, valve cover gasket leaks, etc. Whereas the Rear Main Sealer is less concentrated and specifically formulated exclusively for leaking rear main seals. If you are not 100% sure where the vehicle is leaking or there seem to be multiple leaks then we recommend using BlueDevil Oil Stop Leak. It is not necessary to add both products simultaneously.

    • BlueDevil Pro on November 9, 2020 at 10:29 am

      Renato-

      Thank you for asking about your Audi A4. Yes, if the check engine light that came on was associated to your crankshaft seal leak, and BlueDevil Oil Stop Leak was able to seal the leak, once the code was cleared the check engine light shouldn’t turn on for that reason again.

Kindly advice and recommend.

        You are correct. The BlueDevil Oil Stop Leak would be able to treat the leaking differential seal on your Toyota Tacoma. You will use one oz. of the product per quart of fluid. Expect to star seeing results after 100-200 miles of driving.

    Is it alright to put in your oil stop leak and drive it whenever I normally drive it? Or do I hafta drive it 1 or 2 hours right after I put it in? I rather just put it in and drive it normal if that’ll work to. Thanks

    • BlueDevil Pro on June 23, 2021 at 9:52 am

      Darrell-

      Once you add the oil stop leak, you do not have to take the vehicle on a road trip or an extended drive. You are fine to drive the vehicle like you normally would. Just keep in mind, it will be around 100-200 miles of driving before you start to notice improvement.

      Thank you!
