Liquimoly leichtlauf 5w40. Been told it’s a bit better than 5w30 in a 20+ year old engine due to being a bit thicker. Also does better at higher temps and I drive like a dick
Liqui Moly leichtlauf hightech 5w40. Because it matches the BMW LL-01 specification and was formulated to help with the sticky piston rings issue common to many german engines. Noticed lower oil temp under load and a gradual reduction of oil consumption
I always used redline 5w50 on my S65 runs very well and redline has a great reputation of quality oil especially for its high performance cars. Takes less time to warm up too in low temperature climates.
I run LM 5w-40 as recommended by my tuner.
I've run Redline in my '01 Golf & my '10 Touareg TDI's for Hundreds of thousands of miles. No worries!
I just do the liqui moly. Also I change my oil well before the BMW recommended 10k.
I often go for liquymoly or Motul 4t 10-w40 fully synthetic oil for my big machine.
2004 Dodge Ram 1500 5.7 Hemi 255,000 miles Redline 5w30 full synthetic Wix Filter Lubegard Biotech with each oil change....... 5,000 mile intervals. Had a hemi tick when i purchased used in 2007 {off lease} with 32,000 miles on it. The Redline and lubegard have a hefty amount of moly in them which helps keep the insides slick and hemi tick at bay.
LiquiMoly oil is the best. Top tec 6310 0w30 is what I use for the THP.
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
