Had multiple leaks, heavy oil loss
As my car get near 15 years old and still a daily driver had started to experience many leaks. The BMW community says not to use the product in your BMW. I have a BMW 323i and with the age and mileage was looking at putting a couple thousand into repairs so gave this a shot. Multiple leaks were resolved while one weeper persists. Have ran for over a month with minimal oil loss and improved performance. I did end up flushing out the system after running it with this product in it for the month.

Works, but doesn't actually fix anything
Used this product in a 2012 Civic that was burning a quart almost every 500 miles. This almost put a complete stop to that. I had to combine it with another product in order to stop the oil burning almost completely, but this did decrease the amount of oil burning by at least 40%.Keep in mind this will not fix a broken engine. My civic has a defect from the factory that causes oil blow by - the only true fix is to get new piston rings installed. This wont fix anything - but it will help with oil burning.

I have an older car and this stuff works.

terrible product, killed my engine
had my mechanic use this Bar’s Leaks oil seal repair, thought it would help with a small leak. right after putting it in, engine started knocking badly. not long after, the whole engine was done. ended up costing me around $15000 for replacement. super disappointed, this product did more harm than good. never using again.

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.
