Maximum

I’ve just put this in my Skoda Superb III 2.0 diesel with 82.000 miles. Didn’t notice any difference yet but I’ve only done 200 miles so far so only time will tell if it was worth it or not. Anyway I bought this like an extra protection and I hope I’ve made the right choice

Seams to quiet down the tapping noise on my fiat panda but also changed oil at the same time so could be that as well but Will try it next year again

Would not drive my car 🚗 without this now excellent

is ok

Got 5 vehicles running this now and every vehicle has noticed fuel economy increases and engine noise is lower

Purchased and added to my car as per the instructions. The next day there was an oil leak, I had to take my car to the garage to be fixed and have a complete new tank of oil added.So, no effect whatsoever. Too much of a coincidence for it not to have been caused by this product.

Treat the engine well and it will treat you well

i bought this stuff in january and now its damaged my car, BEWARE. oil pushed into my engine and my spark plug was covered in oil and car wouldn't run properly. now it seems that my oil piston ring has been damaged. my car was fine until i used this stuff
