I use it in my MK4 1.8T. Tuned with 212K miles on original engine and turbo. Still going strong, no complaints.
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.
I was having some issues with shuddering when the engine warmed up. Put in Motorcraft 5w20 synth blend in my 2015 XLT 5.0 and it’s been running like a champ
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.
