Hello all, I'm new here and looking for an oil recommendation for my 2002 Grand Cherokee with the 4.7l v8. It currently has 162,000 miles on the odometer.
Owners manual says 5W-30 viscosity is preferred with the API symbol. It also lists 10W-30 for temperature ranges from 0º F to 100ºF and above. The 5W-30 recommendation is for a temperature range of -20ºF and below to 100ºF
The manual also suggests a drain interval of 3,000 miles or 7,500 miles. I know I meet the 3,000 mile requirements due to my stop and go driving in the city, sometimes dusty roads when off-roading, and driving in hot weather above 90ºF.
I live in California's central valley, where it is very hot in the summers, usually 100ºF and hotter for weeks at a time. The winters get cooler, but never below freezing. However, I will sometimes make trips up to my local mountains where we do get snow.
My driving style is moderate, stop and go city driving, with sections on highways. I will get into the throttle getting on the highway. My daily drive is 10 miles to work which consists of a 50/50 split of highway cruising and city streets.
I believe my Jeep is burning oil. It goes through about 2 quarts every 1,000 miles.
I had been using Mobil1 5W-30 full synthetic, and then moved topping my oil off with the high mileage version. I just bought some Valvoline Max Life 5W-30 oil to continue topping it off with, which is a semi-synthetic. I have also been using a drain interval of 7,000 miles with a standard Wix filter.
I don't really care about full synthetic vs semi-synthetic vs dino oil.
My main question is, what oil should I run? Also, would it be worth changing to a 10W-30 for the hot summers or full time, even though my owners manual says 5W-30 is preferred?
Thanks!
