Doing our first DIY oil change now that the warranty is done on our 2011 Jetta SEL 2.5. Has anybody ran Mobile 1 5w 30 Extended Performance in their 2.5 engine?? Manual says 5w 40 or 5w 30. We live in Phoenix so the weather is obviously real warm to real hot half the year.
IMHO 5W30 is too light for your climate. 5W40 is a better choice. I run it in my car and I live in Northeastern Pa.

Will
