I have an older car and this stuff works.

Burning oil smell stopped
Had a small oil leak that created a burning smell. After adding oil seal during a regular oil change the burning oil smell went away. It came back months later and added more that stopped the burning oil smell again, so it seems to have worked twice. Remember to not overfill your regular oil by replacing this product in place of a 1/2 quart of regular oil.

If it sounds to good to be true.......
Our engine was now where near the leakage this claimed to fix. Never really saw a difference after a couple thousand miles and had to take to a shop for a new seal. I knew it was a shot in the dark. But it made absolutely no improvement.

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.
