2007 Jeep Grand Cherokee drinks oil
2007 jeep grand cherokee, 3.7 liter, 151,000 miles, automatic. Vehicle runs great, driven daily, No codes, no driveway stains, no excessive smoke from exhaust. I have to add 2-3 quarts of oil between regular 3000 mile oil changes. Where is all this oil going?
Already answered this one but mainly it's Warren piston rings you can do a compression test to see how worn they are do a wet and dry compression test
