I need advice on whether to continue using my Chrysler dealer. I drive a Chrysler Pacifica with a 3.5 litre HO motor that is clearly labeled on the oil filler cap as 10W-30. The Chrysler dealer here in Phoenix only has bulk 5W-20 and that's it. It's been around 115F for the past month and 5W-20 seems too light of a grade for the car. What do you guys think. I've read a lot on this forum but still unable to decide. I'm a 3k OCI kind of guy.
