I moved to Pennzoil Platinum Euro Full Synthetic 5w-40 with fantastic results... MPG increase by at least 1 mpg.
2.1L motor.

Based on this review via Project Farm, I feel it will have a better life over time.

Hey guys,

Mobile 1 15w-40 is getting hard to find locally. What do you guys think of
the diesel oils like this the shell rotella stuff like this

32.99 for 5 quarts is way cheaper than the 9.99 a quart for the mobile 1. I
don’t mind paying the extra but if this diesel oil is just as good may as
well save a few bucks. Thanks for any comments. Peace tom
