Liqui Moly300mL Cera Tec

Great product works well highly recommended!

The best additive for your engine, period. My car ran much smoother and the idle at cold start was noticeably smoother as well. This is the real deal.

Simply an awesome product. Highly recommend for any car that uses oil. You won't be disappointed. I use this in all of my cars.

Wife noticed engine was actually a little quieter, I now add 1/3 of a can after every oil change, use in three different vehicles. Do a Seafoam treatment 200 miles before oil change

I feel this product really does improve engine performance and increased engine efficiency by 1-2 mpg.

I always use a bottle of this during my oil change and never had any issues. Gives better protections to all the modern cars with tiny engines with turbos

I've used this for years in various vehicles. I originally got it based on reviews, articles and LiquiMoly reputation. The first car I used it in had a lot of miles.. It ran fairly smoothly I thought but putting in the Ceratech for the first time it ran WAY smoother and quieter within the first few hundred yards of driving it. When I've had engine work on cars I've used it in the mechanics normally talk about how good the engine looks inside. I always use it with LiquiMoly oil as well. Engines seen to last longer which would make sense if the friction modifier is going it's job.

No impressed good synthetic oil better bet
