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.

Good product actually works
Why did you pick this product vs others?:Had good reviews ,but I was still a little skeptic , I have a scion TC 250,000 miles. It’s a 2006.Value for money:Bottle cost versus the repairsOil leakage:Had some leaks around the head and some little other minor leaksSeal:Took care of the oil leaksOil burning:Definitely slowed up the oil consumption
