Engine oil LIQUI MOLY or OEM Audi

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.

Liquimoly

It's made in Germany. My bike is made is Germany. Makes sense to me.

It's a quality product but it's quite a bit cheaper than Motul or Penrite. I like to use something good but I won't overpay for it.

US manual states 507 can be used, but you might get worse fuel economy... Mine is about 0.3 mpg lower on liquimoly toptec 4200 5w-3p
