It actually works!
I was shocked when (a few days after adding this product to my engine) there was no oil leak coming from the engine! Brilliant product!

Suprisingly good
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 đź‘Ť

Think it works!
Rear main oil seal leak. Not a big leak enough to annoy me, as a vehicle technician I am not pulling the box out on my own car a mini r56 cooper s to do a small leak! But this seems to have slowed it right down.

Disappointed – Didn’t Stop 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. Did the job.
Got an old off roader 300TDi defender that had the standard factory fitted oil leaks, banged a tin of this in with some fresh oil and almost instantly after a few miles it stopped the leaks believe it or not. I was quite sceptical about it working as it just looked like water when pouring it in the oil filler but trusted the process and I'm impressed. Engine still acts the same and hasn't seized up or anything weird and wonderful.Would recommend as it worked for my application.
