Engine oil LIQUI MOLY or Pentosin

5w-30. I use LiquiMoly Molygen and my experience is good.

I use it on my 2016 S5 and it’s wonderful. It’s basically the same as Leichtlauf just with the friction modifier and UV capabilities if you need to spot an oil leak (only in the first 300 or so miles because then the oil gets too dirty to work with the UV). I’ve heard the friction modifier works well in older performance cars due to the increased wear of their engines. Yes it’s technically not approved but you won’t go wrong with it.

I use the Leichtlauf High Tech. Really helped my higher mileage SQ5 with chain rattle.

I personally use Liqui Moly. I've tried Castrol, Mobil 1, Amsoil, etc. and my BMW (E85 Z4M) runs noticeably more smooth with the LiquiMoly.

I’ve never had any issues with 5W40 Liqui Moly Leichtlauf.

I run liqui moly molygen 5w 30 oil in mine. Runs ultra quiet and quiets lifter tick. Runs nice and cool and runs like a champ!

I wouldn’t put anything other than Liqui Moly in my Benz. I used to take my car to Wheel Works, but after long drives, it would smell like burnt oil. Switched to LM and started charging the oil myself. I’ve never smelled anything after that for years. It makes a difference for sure.

I’ve have always used higher quality oil like liqui-moly (0w-20 till 60k kms)

I had been using LM in our Euro vehicles for years until prices started to climb. I switched to the appropriate Mobil 1 oil earlier this year. There is not enough difference in test results to make me stay with LM once the price difference became as big as it was during my last TDI oil change.

da última vez papou-me o óleo quase todo, era Líqui Moly.
