    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.

          Will this temporarily stop a front axle seal leak on 2002 jeep wrangler Tj until I can get the seals changed? And which product is best and how much do I add? It has a dana 30 front axle

          • BlueDevil Pro on March 13, 2023 at 9:44 am

            Bill-

            The BlueDevil Oil Stop Leak would be the best product to use for the front axle seal leak on your Jeep Wrangler. You will use one oz. of the product per quart of fluid capacity. You should expect to start seeing results after 100-200 miles of driving.

        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!

          • 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.

            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.

          Thank you!

          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!

          Ken-

          Thank you for asking about your Marshall Tractor. The BlueDevil Hydraulic Stop Leak would be the best product to use, based on your description. You will use one oz. of the product per quart of oil. Expect to start seeing results after 1-2 hours of operation.

            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.

        Thank you for asking about your Nissan Armada. Roughly, how many miles have you driven since adding the product? Yes, once the oil leak is sealed the blue smoke should stop. Feel free to contact our technical support line at 888-863-0426 with any other questions.

        Thank you for asking about your Yamaha. Keep in mind, the exhaust system can produce smoke for several hours before it can completely clear itself out. It should not last, however, and should completely dissipate after allowing the vehicle some more run time. Feel free to contact our technical support line at 888-863-0426 with any other questions.

  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!

      I have 2008 Buick Enclave I see oil on my spark plugs what should I use for that problem also I have a leak on my transmission but don’t know where it’s coming from I know fluid be around the screw on top which is the dip stick as well and it’s not holding fluids I think my seals gone bad what do you recommend

      • BlueDevil Pro on April 26, 2022 at 8:27 am

        Grady-

        Thank you for asking about your Buick Enclave. Is the oil getting onto the spark plugs and burning off through the exhaust pipe? If so, we recommend using the BlueDevil Stop Smoke & Engine Repair. The product would work great for valve guide seals or worn o-rings.
        The BlueDevil Transmission Sealer is intended for leaks that are seeping or lightly dripping, from worn/shrunken rubber seals/gaskets. If the leak is coming from a worn seal, we would recommend the Transmission Sealer in this instance. You would use one oz. of the product per quart of fluid capacity.

Just a couple drops seeped out afterwards,Will be using a second bottle to seal the deal,also will be using this to take care of a very small but concerning differential axle leak…first time ever trying this product and i love it!

        I have the same car but I have white smoke coming out due to a oil leaks as well would it stop my leak as well for good or will it be a temp repair

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

          Mario-

          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.

          Thank you!

      Paul-

      If the leak is coming from out around the rubber seal then yes we recommend using the BlueDevil Oil Stop Leak to stop it. Be sure to use the proper amount of BlueDevil; 1 ounce of BlueDevil treats 1 quart of oil.

  14. Dan on April 8, 2015 at 4:22 pm

    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.

      Feel free to contact our tech support team at 888-863-0426 with any further questions.

    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.

    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

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

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

    • 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.

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

      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.

      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.

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

          Malcolm-

          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.

      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.

      Thank you for asking about your Ford Explorer. Based on your description, we would recommend 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!
