Engine oil LIQUI MOLY or Motorex

Liqui Moly is good stuff, not sure about the other one... Personally, I run Redline in all of my high mileage VW's.

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.

In my Shiver 750, Motul or Motorex every 3,500 miles were required to keep neutral findable when you want it and hidden when you don’t. False or impossible-to-find neutrals were a sign that it was time for an oil change.

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.

Liqui Moly Leichtlauf (the dark blue bottle) 5w40: This is the oil I ran this sumer, and I'm on my second oil change with it. This oil burned about 2 quarts during both intervals, but did not seem to thin out or break down at all.
