Engine oil LIQUI MOLY or Castrol

Castrol Engine oil

Castrol is notorious for getting dirty very fast (detergents is the popular explanation). Why I like Mobil 1 a lot, doesn't discolor nearly as fast and still a very good synthetic oil.

Pros: good synthetic oil
Cons: gets dirty fast

Thanks sp_golf - went with liqui moly 10w60. it may be my imagination, but the motor seems to run a little smoother and it feels more responsive - but I have no #'s to prove any of that. What I can prove is my oil temps were definitely more manageable and I didn't burn nearly as much oil as the 5w40 I was using previously.

Pros: more manageable oil temps
Cons: no #'s to prove

Liqui Moly for me all the way. It's made in Germany and their standards are second to none. We use their oil in our service department and in all of our own personal and show cars as well. Their oil test results are some of the best I've seen, I highly recommend using them.

Pros: best oil test results
Vehicle: Volkswagen

Castrol Engine oil

Castrol 0W30 (a.k.a. German Castrol :thumbup seemed to shear thin very little over a similar interval, which is why I preferred it.

Pros: shear thin very little
Vehicle: Volkswagen

i got even better results with Liqui Moly(better results then Euro M1); a much quieter engine on a 1998 Dodge SUV V8 and a 2001 BMW with a V8.

Pros: much quieter engine, better results than M1
