This product helped my oil pressure light to come on less frequently
I bought this product to help stop my oil from leaking from my engine. My oil pressure light was coming on after I changed my oil and I also noticed that I was getting oil spots under my van. I put this product in my engine and noticed that the oil pressure light isn't coming on as much.

Actually works for burning oil
Actually works. Had a car that burned oil bad due to a poor engine design! This kept the oil contained. However I found this needed to be constantly applied to work. Not just one and done in my situation.

Good Product For Older Vehicles
I use this in my 1966 Ford F-100 that still has the original drivetrain with 139,000 miles on the 352 V8 engine. As with these older vehicles, they used a rope seal for the rear bearing, which always leaked. Bar’s slows down the leak when used regularly during oil changes and when oil level is low. It doesn’t fix the rope seal from leaking, but does slow it down.

Does not get rid of smoke
I drove the car per instructions and still has this smoke in the morning. After that it’s fine. It’s only a one time per day occurrence. I may need to get my injectors cleaned. But this product may not be for newer cars.

Works goods for small leaks or damaged seals
I used a ton of this S* in my Mountaineer before I realized that my F* oil sensor plug was actually leaking. $20 and 15 minute fix. However, I use this stuff in all my older vehicles and any seal leak stops after a week or so. Good S* ! A must for older motors. Good price.

Worked great at slowing oil burning / leak
Impressed with how well this product help reduce the amount the of oil consumption and oil leaks in our 2008 6cyl , 175K mile car. While the car still has a leak somewhere as I can smell it hit the exhaust pipe at times, it is not leaving alot on the ground like it was before. I will likely keep using this product after each oil change until we eventually just get rid of the car.
