Which Mobil 1 is everyone using (0W or 15W)

 

For motor oil, it would be best to stick with the factory recommended 5w-30 weight. Lighter weight oil is only good for improving fuel economy, and may accelerate engine wear. Heavier oil will offer less protection during cold starts, and will tend to reduce fuel economy.

5W-30 performance (red cap)

 

i thought 5W-30 was a blue cap...

 

It is blue.....

 

New vehicle = blue
Performance/high temp = red

And you are correct, my bad, the 5w-30 only comes in blue cap.

Too many cars, too many stats........

My 911 calls for Mobil 1 0-40 and I use Mobil 1 5-30 in my MB 430, I would stick with the Viscosity that the Mfr. calls for.
