Engine oil LIQUI MOLY or Eneos

Liqui Moly 10w40 MoS2

These are old engines, they were run on garbage oil and only idiots go bragging about this, regarless the old standards included zinc and other additives no longer available today due to environmental protection regulations. Ive had 7 of those classics pre 1990s and all of them got the MoS2 treatment - the engines turn around after 2-3 oil changes. Sparkling clean. Smooth.

Any oil that carries the BMW LL-01 approval should do the trick.

I’ve used German Castrol(aka Castrol Syntec 0W-40 made in Germany) or Liqui-Moly Leichtlauf 5W-40 in my old 650i with no issues.

my switched his n55 to liqui from bmw dealer oil and he said it runs wayyy better and quieter.

Since started using Liqui Molly (2 years and about 8k ago) fuel consumption improved by at least 2/3rds and the oil consumption slowed down not to mention top end is much quieter.

Liquimoly Leichtlauf (Hight Tech) exceeds factory standards, and is designed for VW engines. I’ve been running it for years in our Tiguan with a Mann oil filter. It’s a great oil, our 13’ tiggy runs great and is the only oil I would ever run in an old TSI motor.

Make sure you stick to the VW 502/504 ratings. I've been using LM leichtlauf in my 2018 sportwagen for years and its been great.

I do every 10,000 KMs and liqui moly as well, it’s the best

I've run only liqui moly through here since buying it with 30k miles with oil changes every 5k.

I was happy to see everything looking pretty clean after 100k. I’ve run only liqui moly through here since buying it with 30k mile

I am burning around 0.75qt every 2k KM (1200 miles). I've also tried all the vw508 different oils hoping for a better outcome (vw brand oil, liqui moly 6200, motul specific 508) but no change really. at this point i live with it but always carry around a spare 1-2qt if you are travelling far away in the back.
