I just purchased an '03 jeep wrangler with 61,000 miles on it. I was wondering what is the best oil brand and filter I should use to get the max life out of my jeep. I want to run this thing until it hits 300,000.
I like mopar the best but will also use wix or napa. ( I have heard wix makes all of them!) for oil 6 quarts of any of the top brands in the correct viscosity. I like castrol, Amsoil, or royal purple. I change mine every 4 months or 3000 miles
