Rating 4.5

Imo Mobil 1 is mid grade at best. Liqui-moly is the only thing I’ve used for the last 5 years, I too started with Mobil 1, then switched to liquimoly (same weight) and the engine was immediately quieter, smoother, and ran cooler.

Pros: quieter, smoother, cooler engine

Cons: Mobil 1 is mid grade

Take liquimoly for instance, they only have certain oils that meet the VW 508 00 spec but many of their oils are the same weight. None of which will cause your engine to explode if you use them.

Pros: high quality oil brands

Vehicle: Audi A4

My GL550 has about 106k miles on it, just did an oil change with LiquiMoly 0w-40 and 2 bottles of LiquiMoly ceratec. Drove it kind of hard for a minute or so. Then noticed when I got back it had this noise.

Cons: noise after oil change
