Re: 2006 Grand Cherokee Laredo - White Gunk on Oil Fill Cap
Are you driving a lot of short trips? If so, then the oil never gets hot enough to burn off the white gunk.
Back in the 90s, Quaker State and Pennzoil had the reputation of wax buildup, but supposedly that has been fixed.
How long has it been since your last oil change?
