As a car ages, engine seals harden and shrink from the plasticizers being removed over time. This means leaks, and nobody has time for that. This professional strength synthetic stop leak revitalizes these worn seals and gaskets to restore them to like-new performance. This is our strongest formula ever to stop main seal, valve seals, timing cover seal, cam seals, crankshaft seal, oil pan, valve cover and all other oil leaks.
This product is incredibly effective against oil leaks, but what about oil burning? We have that covered too. There could be two possible reasons as to why your vehicle is burning engine oil. It may have an oil leak or you it could be burning oil during the ignition cycle. One common problem is if the cylinder walls are allowing oil to leak up from the bottom of the engine, past the piston and into the combustion chamber. So when the fuel ignites the oil does as well, and then expels it out as exhaust. Before you know it, you’re dealing with an oil burning problem.
The good news is that with a single application of Bar’s Leaks Oil Seal, those problems will be history.
Your vehicle is a good candidate for this solution if it does not consume more than one quart of oil per day. We have designed this product to work in all gasoline and diesel engines including turbocharged, EcoBoost, hybrid and even racing engines. This covers 3, 4, 5, 6, 8 and 10 cylinder engines in all cars, trucks, vans and SUV’s. Our product can also be used in heavy-duty applications referencing the appropriate dosage level. This applies to a wide range of other motor applications too: tractors, boats, RV’s, motorcycles (including wet clutch), ATV’s, lawn equipment.
You have a life. Your life needs a car. Don’t let oil leaks or burning get in your way.

Absolutely the product I depend on. 350k miles and running strong!
2011 Buick Enclave has been acting up and very valve noisy regardless of gas octane. I did an oil change with your Oil Seal and when I started you can hear the tic tic tic noise and in less than minute it was gone!
Added to my 1999 Hyundai 2.4L engine during oil change. So far so good. Oil smoke from exhaust stopped after about 75 miles of driving. Strongly recommend this product.
Have a 2001 BMW E38 740il with the MU42TUB44 engine - 142,468 miles at last oil change 2 days ago. I put this in to primarily protect and restore the valves and seals - quiets everything down immediately and noticeably - Vanos timing chain guide failure my biggest worry - understand the perceived inevitability of it - but timing chain rattle nonexistent on start up right through to any tapping or ticking noises reduced from subdued to very quiet.
No engine issues other than very, very minor oil leakage, have original Vanos guides and timing chains, drive conservatively - works beautifully with Castrol Synthetic A3-B4 5W-30 Euro Formula Oil. Bar's Leaks Oil Seal is a compatible synthetic-based formula. No commercial message intended - just a pass along to fellow BMW MU42TUB44 engine owners with minor small issues for preventative maintenance. Really happy with the product.
I was losing oil from the engine. I had heard about this product and thought to try it, and it worked well.
Oil Seal OS-1 is the product I used.
The engine is an old Chevy 350, 182,400 miles. It’s going to be leaking oil and it did. After 2 applications your oil seal sure did the trick. I think of it as part of this old truck’s maintenance schedule. I’ll be adding a bottle every other oil change. It works!
Oil Seal OS-1 fixed my valve seals on my 4.0L OHV Ranger for 3 months until I had the warner weather to repair properly with hard parts.
I used Bar's Leak - Oil Seal Engine Oil Burning & Leak Repair (OS-1).
I have 2002 Toyota Corolla LE and it was leaking oil from engine too much. Due to that, I had to constantly add engine oil. Also, I was getting a burning smell. After using Bar's Leak - Oil Seal Engine Oil Burning & Leak Repair (OS-1), the leak has completely stopped. I don't get any burning smell and I don't have to add oil anymore. I was very happy as it saved me from expensive repair.
My wife's 2005 Camry was losing oil somewhere. There are tons of other products on the market but my research returned me to Bar's Leaks. The main cause of concern was for the VVT engine in the Camry and, from my research, the (OS-1) Oil Seal was designed with this in mind. I'm not going to lie. At first, I was very skeptical but after the first couple of days I was very impressed! I was even more impressed a couple weeks later when it was still keeping all of its oil and I noticed that the wet oil stains around valve cover was dry! This product is amazing and the company offers great customer service along with a great warranty! Thank you!
I used Bar’s Leaks OS-1 on the recommendation of my mechanic, who told me that my 2005 pickup truck had a gradual and slow loss of engine oil being caused by what he described as more of ‘slow seepage’ than a true leak. After one application of OS-1 (added a quart during a routine oil change), I no longer detected the smell of burning oil coming from the hood every time I drove. I now have the peace of mind of knowing that my oil pan life has been extended as I continue to avoid a costly repair and close in on 200k miles!
