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.

My old Suburban had an oil leak that wouldn't go away for months. Finally got sick of it and went to Autozone and asked if they had anything that would help. Did NOT want to spend any money on a full fix if possible because the truck has over 160K miles on it. Autozone guy recommend Bar's Leaks and it worked within 30 minutes of me installing it. It's been 6K miles and still no problems. I can't recommend this product highly enough!!

Ever since I heard of Bar's Leaks Oil Seal, I have added a bottle when I change oil. WOW. I do not see any spots on the floor! It works great! I have finally found something that does what it says it will do. I am not anxious to pull everything to replace the seal since I have a 4WD vehicle. I love this product and wanted to tell you how great it works. I am telling everyone about it! Thanks.
