Rating 4.0

I recently changed the engine and transmission oil in my car and opted for Liqui Moly, as from what I researched it withstands higher temperatures compared to the OEM.

Pros: withstands higher temperatures

I’ve personally been running Liqui Moly LL-04 5W-30 as this grade seems a lot better to be using in a high performance engine to induce longevity. Plus the gen 2 B58s don’t have the same oil pump issues as the gen 1.

Pros: better for longevity
Vehicle: BMW

I’ve done testing on 0w20 and 0w30 and less wear metals in the 0w30. I’ll try 5w30 in the spring and see how that goes. Doubt I’ll see much difference unless the additive package is different than the 0w30. Both oils were liquimoly and changed at about 5k miles.

Pros: less wear metals
Mileage: 8000 km
