We use the 5w 40 leichtlauf in the b8 S4 and a3 8v. Helped with the s4 oil consumption a great deal over the euro castrol edge used previously.
liqui moly 5-40 exclusively
Molygen entirely stopped my tensioner rattle, like, didn’t reduce it, took it from 1-2 sec on startup to never rattling again
Liqui Moly is fantastic oil. It's a pretty fair price for me, so I always run it and have had great oil analysis when using it.
Liquimoly molygen 5w40 doing great in my 313k motor.
I use liquimoly leichtlauf 5w-40. Bit of advice: these are VERY easy to overfill if you're not careful, so refill slowly. Put in less than you think you need, once it registers on the oil level sensor, then start the car for a minute. After that, leave if for a few hours to drain before continuing to fill.
amazon.ca has Liqui moly TOP TEC 6200 SAE0W-20, VW508 00/509 00. Been using this since day 1 on my 2021 Tiguan with no issue.
I buy Liqui Moly 6200 from germanparts.ca for about $70/5L. Our Tiguan consumes a lot of oil sadly, so I buy a lot of it. My mechanic recently recommended using Liquid Moly 2331 (Leichtlauf) 5W40 to see if it helps with oil consumption, and have had that in for the last month or so.
Liqui Moly 0W-20 LR for my F-Type-R. Doesn't use much oil, so cost is somewhat irrelevant.
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.
