I have a 99 Intrepid with a 3.2L and it specifies 10W-30. I understand that there were engine problems using 5W-30, so Chrysler specifies 10W-30.
That really doesn't make any sense that an engine would have problems with 5w30 compared to 10w30 though. The difference in viscosity between those two under most normal temperatures is usually very close.
