Being as i drive an older car it does leak from time to time. I bought this as i couldnt find the same product by WYNNS instore. I usually get WYNNS products as i find them best on the market but thos was the only one there. It did work but took longer and hasnt completely stopped the leak but considerably slowed it. I will hunt down the wynns product and try agaim.

Works Great! Better than expected.Added this to our 2011 Skoda Fabia. Drives very well touch over 100k kms, quietened the engine down a lot, it appears to be reducing oil consumption. Would only require a top up every 3000kms, but seems to have slowed that considerably.On special this is definitely worth it.

Great thick product. Does a good job on limiting engine oil leaks.
The mechanic diagnosed my car as having head casket problem.Pured a bottle of the above, and got my car running again. Takes about 2 - 3 days to work.
Stopped engine oil leak from a Volkswagen with over 34000 kilometres on the clock
I've noticed that my oil leaks have almost vanished from what it used to be.
This stuff worked like magic. Oil leak stopped in less than 20 klms . Amazing!
I brought this product on a recommendation and had little to no expectations. I was surprised to learn that it worked immediately to block and stop my main seal from leaking any further.
works on small leaks, does what its intended for but save your money on the bigger leaks and just repair the part as this won't perform miracles.
