Therefore, although I have used Mobil1 synthetic oil exclusively in all my vehicles for more than 30 yrs, and even though M1 0W40 is VW 502 approved, it is not the recommended viscosity, so I now use Liqui Moly Leichtlauf high tech 5W40.
My Good ol' Beast only gets Liqui Moly 5W-40. Has just 127k miles on it. it runs the best on it and is rev Happy too.
Leichtlauf every 5k for me with Certech added in every 30k.
i just use liquimoly leichtlauf. really can't go wrong with it.
Liquid Moly Molygen for me
After NGP rebuilt it, I noticed they use Liqui-Moly everything. After I read up on it, I switched to LM exclusively.
2017 Sport. Liquimoly Molygen. Every 7k…about to do my third oil change.
liqui moly Leichtlauf 5w40
10,000 mile intervals
2015 mk7 with 115k miles stage 1 EQT. oil analysis always comes back very positive at these intervals.
as i am not currently tuned i run LiquiMoly 0w-20 and change the oil every 5k miles.
The Liqui Moly fully synthetic 5w-40 has similar properties at below -30° Celsius to many 0w-40 or 0w-30s. It is very good oil, I went from Mobil 1 0w-40 to the fully synthetic LM (also available from Meguin for a cheaper price) and it is definitely running smoother.
