Idk how to tell if this works or if this is snake oil. But I’ve been recommended by a lot of people to use it so I’m trying it out in my 2009 Benz. Fast shipping like usual!!!!

Have used this in my 280K Murano for years, smooths and quiets the wear ..... Used in in the X3 with good luck in over 90k that I owned it.. (160K motor).. same thing noticed smoother idle , quiet.. Added it to my ONAN and Honda generators, air compressors.. have not had issues, used it in RV, 460 ford, funs hot, had coolant go bad, fried the oil , motor stayed together, i dropped pan to check..., not sure if ceratec helped but it did not hurt.

Not sure if this stuff works but gives great peace of mind

I've used this additive on my German and Japanese cars. So far, so good!

Added this to my 92K 2013 Volvo XC60 and the engine has been running smoother, changed the oil last month and so far, so good. Will keeping using it every year.

MB dealership told me I needed valvetrain work (start up chattering). After a bit of research I found the c63 needed 5w40 instead of 0w40 and use CERA TEC to get everything properly lubricated. Problem solved and saved $4k.

I definitely felt like my car reved and idled higher when I used this in my BMW 530i which would support it having less friction. I trust liqui moly products so I have no problem putting this in my Mercedes engine

Use it on all my euros. They run smooth.

No noticeable change in sound or performance but gave me peace of mind on a vehicle with little maintenance history

Always a sceptic when it comes to any additives but this has proved to work as advertised. Put into our mini (2005 Supercharged) and it quieted almost all the weird ticks i was hearing from the engine. I used this after the engine flush (also recommended).
