Which oil is better for extreme usage: Mobil 1 0w40 or Motul 0w40

 

Neither. The Motul you'd want to use is the 8100 xcesss which is a 5W-40 and Porsche A40 approved. For extreme usage, the better choice is Joe Gibbs Racing Driven DT40, also a 5W-40.

 

You can use either of them...

M1 Euro 0w-40 meets Porsche A40 specs and is a fine oil. You can get it for $22 for 5 quarts.


Motul 0w-40 Xmax is a fine oil too and meets Porsche A40.


Motul 5w-40 Xcess is a fine oil and also meets Porsche A40.
