I have a 08 Mercedes r350 with a tick and smoke every time I would start in the morning It looked like a smoke screen when I put this in my motor after driving 100 miles it's like I dumped a bottle of microbots in my motor liquid moly is the real deal out shines every other additives nothing can touch this stuff my car feels and drives like it has 200 miles on it when it actually has 289000 miles on it shes quiet and performs better than the first day germans are always way ahead of their time. I will never touch anything else I'm a moly customer for life.

This stuff is awesome. I just did an oil change on my 2001 suburban with 400k miles and It increased my oil pressure at least 10lbs. Very impressed. Even made the engine tap disappear. Will recommend.

I’m going to purchase this product again. I drive a lot and it’s perfect for me and yes, it does work in my opinion. I noticed a difference right away after the oil change. My vehicle was much smoother.
