I love Liqui Moly

I love Liqui Moly.

I just did an oil change on the Mercedes S500 and used their engine flush stuff.
The oil flowed out like butter. The engine runs tangibly quieter. I'm floored.
Granted the car desperately needed an oil change, and had a moderate amount of sludge when I changed the valve cover gasket.
Even still, between the valve cover gasket and today I'd done a "professional cleaning" which included an engine oil flush.

I'm thinking of trying their cera-tec, although I'm hesitant as it's an additive rather than something that just cleans the engine.

Used the flush in the prius's last oil change... looked like pretty dirty stuff coming out. The new oil seemed like it may have stayed 'golden' color for longer, but who knows.

I've used the cera-tec in a few changes in the zhp and eventually stopped. Didn't really do anything noticeable in my case.

I am strongly considering trying the lifter additive. Wondering if autocross guys have used that... I guess these things get some mad lifter tick out in the parking lots/tracks.

But yeah, they do make very good products, as far as I can tell.

Actually, I take that back. I used the MOS2 anti-friction additive, not Ceratec.
