Wynn's Engine Oil Stop Leak - Prevents & Stops Oil Leaks - Restores Elasticity of Seals & O-Rings - Lubricates & Protects Engine Seals - Safe for All Engine Oils - 325ml

Very good it works I was losing 2 L a week of oil now it stopped. We’re definitely buy again if had to. I recommend this item to others.

Had a bad leak on main seal VW 1.6 aircooled. I could have dropped engine and changed seal but thought I would try as cheap easy alternative. Didnt expect much but it suprised me. Stopped leak after about 30 miles and 5000 later still no sign of the leak. Due another oil change now so lets see if it still holds out. Give it a try if only to buy some time. RECOMMEND 👍

Easy to use , no issues

Had a small but persistent leak forming on the gearbox to engine seal so bought this in case it was an engine issue and another product for the gearbox. Leak stopped within 200 miles. Also served as an excuse to change oils in both engine and gearbox. Let's see how long it lasts but as I couldn't find the leak visually, I assume it was some sort of internal o ring or seal? This stuff apparently reacts with the rubber material and makes it more pliable? Anyway hopefully good for the 12 months I plan to have the vehicle and no expensive repairs needed. I did also mix some Lucas stabiliser which is also awesome

works well

A good product which i have used many times before, its easy to use and functions well. Delivered quickly and at a reasonable price.

I had high hopes for this product, but unfortunately, it didn’t work for me. I followed the instructions carefully and gave it time to take effect, but the oil leak in my engine continued just as before.There was no noticeable improvement, and I ended up having to book a proper repair. It might work for very minor leaks, but in my case, it didn’t deliver.Disappointing result, especially considering the claims. Wouldn’t buy again.

It's work well
