Astonished after first drive with Ceratec. The PCV system failed on my '14 volvo s60 and ever since the repair I've noticed engine vibration. Replaced motor mounts, spark plugs, and more with no results. My dealership did an engine flush with BG Epr and I put this in, and I can only say I'm a believer. Car feels almost new. I'm eager to see longer term results.

Love this stuff, Like all Liquid Moly products. Notice a smoother running engine......

Works great, and you can actually tell the difference after couple 100 miles. Engine is way smoother

Stuff works great! Engine seems much quieter since using Liqui Moly Ceratec and Molygen. It even reduced temp and timing chain chatter on my Jeep JK 3.8l at 218k miles.

Great product never do an oil service with out it get you case of it AWSUM product! 2001 bmw 330ci coupe m54

This is an excellent product. Used in my MB w210 2002. Engine sound detectably lower and runs smoother. I use twice in last 2 oil changes with 3000 miles interval using Liqui Moly.

I bought this stuff for my turbo Volvo with 200K miles. It dramatically reduced engine noise - almost purrs like new again.

My girlfriend started using this from 10k miles on a 2016 under dealership warranty and it has consistently had better gas mileage and runs as smooth and powerful as ever. Its best to start using this after the first oil change on a new car for the best protection. Nothing but good things to say about it.

I user this product after I used the liqui molly engine flush and I say they should be used one after the other. Very happy with all liqui molly products. I do notice the engine runs a lot smoother and a bit more quieter. I love fcp euro thanks guys

Autopsy your engine after its death... I find no difference.
