Engine oil LIQUI MOLY or FUCHS

Fuchs Titan GT1 5w30.

Liqui Moly leichtlauf hightech 5w40. Because it matches the BMW LL-01 specification and was formulated to help with the sticky piston rings issue common to many german engines. Noticed lower oil temp under load and a gradual reduction of oil consumption

I run LM 5w-40 as recommended by my tuner.

I just do the liqui moly. Also I change my oil well before the BMW recommended 10k.

I often go for liquymoly or Motul 4t 10-w40 fully synthetic oil for my big machine.

LiquiMoly oil is the best. Top tec 6310 0w30 is what I use for the THP.

I used to have a B8 and kept my oil level OK as per the MMI and only used Liqui Moly oil.

Liqui moly 4210 pricy but dropped my temps 10 degrees 0w30 vw 504 rated..

Fuchs is excellent oil, run it in my nismo 370z cause it has specific esters that the cylinder liners need. Don't think it's necessary BMW engines but it is very good quality oil.

Ughh. How did I miss that! I thought I was just saving $5 a liter for the same thing. I am so annoyed with myself. :banghead: I just pulled up the specs for both and indeed the Synthoil has a viscosity index of 171 vs 180 for the Leichtlauf. Also the NOACK for Synthoil is 12.9% vs 10.0% for Leichtlauf. From what I can tell the 12.9% NOACK of Synthoil is what doesn't allow it to have the VW 502 00 approval.
