We run LiquiMoly 5W-40 in all of them. UOA testing of heavily modded cars shows significantly less wear on engines running LL-01 oils vs the LL-14FE piss water.
Switching from Mobil 1 to Liqui Moly pretty much solved the burnout issue for me.
I go for liqui Molly 5w-30 4200 top tec for my r55 mini Cooper D
I run Leichtlauf 5W-40 on my B7 A4 2.0T; just hit \~250K km. Used to run Castrol and Motul but as I started doing my own oil changes, switched to the LiquiMoly stuff. Oil consumption issues gone, no complaints from me.
My 3.0T doesn't seem to care one way or another what gets put into, it all seems to act similar. I have liqui moly molygen 5w40 in it now because...My 5.2 absolutely hates Mobil 1, Castrol Edge and Valvoline Syntec. Burn off/deposit rate of liquid moly molygen or leichtlauf seems to be about half of the other 3 I've tried, so I'm just going to stick with that until I see a reason to change.
Yes, liqui moly great german quality, can recommend
LiquiMoly Leichtlauf 5W-40. (blue bottle). It’s got great anti friction properties. Using it for past 40K miles. No issues.
I run Liquid Molly in my Audi SQ5, great stuff for a high performance engine.
I use 0w-20 liqui moly molygen full synthetic. Really a great oil.
For those who aren't certain about which oil to use, I've read that the "fully synthetic" oil in the USA really isn't fully synthetic and the Liquid Moly stuff from ECS tuning might be a notch or two better than the Mobile 1 from WalMart*.
