I’ve ran 0w40 in mine, made absolutely 0 difference vs 0w20 and 5w20, except the oil pressure while cruising was 40psi instead of 30 according to the EVIC.I've used 5w-30, 5w-20 and 0w-20 in the Caravan. Both Pennzoil and Valvoline and currently running VWB. I don't lose any sleep over specs. I'm easy on the motor when driving and change the oil at reasonable intervals.
Some people are super paranoid about not using the proper spec in the owners manual. How did we survive 20 years ago???
