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

My daughter's 10 year old car developed a slight leak so I changed the oil, oil filter & drain plug although it appeared to be coming from above the sump. After all the above, it still had the same slight drip so put a can of this in & it's only been in a week but it appears to have solved the problem (fingers crossed cos I only bought her the car to teach her to drive in and she passed and wants to keep the car so I'm hoping it's fixed as I resent spending a lot on a nearly 11 year old car)

works well

Seems to have slowed the leak

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.

Good
