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
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.
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?
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

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.
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.

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

It does not have to be a continuous drive or be driven immediately upon adding the product.

I put whole bottle in 2007 yamaha 650 Vstar and its been smoking past two hours still smoking is it okay
Marcus-
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.

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?
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.
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?
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!
-BDP
I have a 2001 Jeep Cherokee automatic transmission.
Water has entered the oil and trans has stopped working.
Do you have any treatment product that I can try to fix the transmission?
Hope to hear from 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
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.
Thank you!

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
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!

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?
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.

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.

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
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
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.
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?

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

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.

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.

Hi, I have a 2006 Ford F350 with a 6.0 diesel. I have a small amount of oil getting into the coolant. Will your product help, and which one to use?

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.
Thank You!

I poured in bluedevil. About 40 miles. Later my oil capacity was 2 quarts low. It was full before I poured it. Why do I have to add more oil
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.
Thank you!
-BDP
Im about to pour the blue devil oil stop leak but i was wondering for how many miles should i drive it and if i should do a oil change right after i drive those miles?
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.
Thank you!
-BDP
I used blue devil oil leak last week, drove over 100miles. Still leaking but just found out it is coming from the rear main..Can I add another bottle now specifically for the rear main? Or is that too much should I do an oil change first? This is for a 2004 vw passat
GMG-
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.
Thank you!
-BDP
Is this 100 miles of constant driving? Or will the effects be the same as long as I drive 100 non-consecutive miles?
John-
Typically, 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 drive in 5,10 mile intervals, it’s just going to be around the 100 mile mark before you start to notice results.

I have a 2,5 v 6 xtyp jaguar slow leaking oil when driving seems to be coming from sump does this product work and would it affect the running of the car in anyway and would it be alright with the timing chain please help
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.
Thank you!

I have a 1975 outboard motor with the prop seal leaking. Is there are Stop-leak product in Canada that would work for a gear case that doesn’t get hot or see 100 miles equivalent use?
Thanks.
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.
Feel free to contact us at 888-863-0426 with any questions.

I just bought some of this I’m scared to use it because I have a pretty bad leak in my crankshaft seal on my 99 vw Passat it says to drive it for 2 hours but I am scared to seize my engine or break down the leak is like a water faucet turned on a little bit will it work??
Timothy-
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. Feel free to contact our technical support line at 888-863-0426 with any other questions.

Hi,
I have a 2007 BMW 550i with a leaking alternator-bracket gasket/seal; i hear it’s a common problem with these v8 engines.
Will your product(s) help stop the leak and which of your product do you recommend?
Can your products be used together such as the Oil Stop leak and the rear main seal leak stop?
Gary-
The BlueDevil Oil Stop Leak is the universal application and will work for oil pan leaks, rear main leaks, valve seal leaks, etc. Whereas the Rear Main Sealer is specifically formulated specifically for the rear main seal. If you are not 100% sure where the vehicle is leaking or there seem to be multiple leaks then I recommend using BlueDevil Oil Stop Leak.
Thank you!

Can I use this to seal a leak of oil from my head gasket. I have a 94 Honda accord and oil is leaking from head gasket in the front maybe back but can’t see it.
Sir-
Thank you for your question. The BlueDevil Oil Stop Leak is intended to treat leaks from the rubber seals or gaskets, not the head gasket itself. Unfortunately, we do not manufacture a product that would seal oil leaks from the head gasket. Feel free to contact our technical support line at 888-863-0426 with any other questions.

I have a 2002 Ford Explorer with a V8. It seem’s to be leaking oil from the valve cover and maybe another part. Would this be a simple case for BlueDevil?
Shaun-
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!

I have a 99 F350 and I get a puff of white smoke every now and then probably from a worn turbo seal. Will blue devil stop leak help the problem? Please let me know.
Cooper-
Thank you for asking about your Ford F-350. Are you noticing a loss of oil? White smoke would indicate water/coolant burning and blue smoke would indicate oil burning. Please contact our technical support line at 888-863-0426 so that we can get a better understanding of the vehicle’s symptoms and be able to make any appropriate recommendations.
Thank you!
