I have an 01 Grand Cherokee 4.7l with 113,000 miles on it, manual calls for 5w-30, only spec I see is API. I live in Anchorage, Alaska, drive moderately, maybe 40-60 hwy/city. No known engine problems, been driving really well since I've bought it
Currently has a Mopar filter in it and Pennzoil Platinum PP 5w-30 that's been changed as of today. Unknown oil before that, had gone ~2000 miles since prev oil change if previous owner is to be believed. Going to do an oil change and UOA in 4000 miles, but I am curious what your guys's recommendation for oil and filter will be.
