Engine Oil Stop Leak 325ml Wynns 77441

It did what it said it would.

Quality product from a top company. I had a small amount of oil loss from my engine and this stopped it within days.

Didn't work for me

I bought this product to stop a very slight oil leak on 3.2L BMW but unfortunately it hasn't stopped the leak, after a hundred or so miles my leak had practically stopped, but now it's worse than before, Maybe my engine is too larger capacity for this product, and maybe I needed two cans of this product, or maybe my leak has just become too severe for this product to work. But either way I can only rate it as I find itRead full review

Stop leak.

I put new oil in, added this product expecting it to at least help. Hasnt help at all, if anything it smokes more. It may work for others but not for me. Waste of money.
