Wynn's Pro Engine Oil Stop Leak - Restores Seal Flexibility & Prevents Oil Leaks Without Dismantling - Safe for Catalytic Converters - Compatible with All Oils & Engine Types - 325ml

I took a chance using this as I didn’t have the money or the time to investigate the oil leak before the mot retest date.All I can say, is that for me the product has worked. It needs time and miles and the engine to be at normal operating temperature to work better but it has stopped the leak. But it isn’t a miracle cure.I still check the engine oil level and I will get the leak looked at but this has given me some breathing space so I think it’s worth it.

I was not overly hopefully when purchasing that this would do the job. Having tried Wynns standard version a while ago for a small leak I was left disappointed. However I thought the professional version might do better as a temporary fix until I isolated the source. Well it worked far better than expected and in line with other online reviews. So my faith was restored in Wynns. I'm sure there are better products on the market but at this price point you have a good solution for your car and pocket. (Though I doubt any additive will stem a huge leak, so be reasonable in your expectations).

Iv used this before it keeps the seals soft and slows leaks down to a acceptable level

I had quite a significant oil leak from my sump gasket, on my car is extremely difficult to replace as a quarter of the sump bolts are blocked by the gearbox. My car was leaving a drinks cup lid size patch of oil behind where ever it was parked.I stuck this in at 103533 miles, the cars now done 103598 miles and the oil loss has already reduced to the size of a £2 coin.The product does need 300 to 600 miles to be fully efficient however, the early signs are excellent and to reduce the size by such a significant amount so early on I’m confident in saying it works.I didn’t expect it to resolve the leak fully but, given how effective it’s been in reducing the leak so far I’m really pleased with it.

It did not stop my tiny oil leak unfortunately

I had a small leak upon using this stuff after 200 miles plus my leak has vanished and I feel I have more engine pressure when accelerating ,Nothing more to say, I'm impressed.A* ~}

Not sure if this worked or not as I replaced seal after i had found the leak

It did not work for me so I can’t recommend it but I am sure it’s a good product

This product closes the little leaks and also renovates the plastic and neopren parts or sealings inside the engine.

serve per limitare eventuali perdite mentre aspetti il ricambio

TTog ett tag (ca 100 mil), men sen slutade det helt att droppa från motorn.

Ok, bien reçu
