Jeep XJ Parts and Reference

Engine

Oil: 6 Quarts 10w30 or 5w30

Oil Filters

To my knowledge, all filters below fit all Jeeps with a 4.0 engine regardless of model or year  
"Large Size" filters fit the same as stock, but house a larger filter element. They also hold slightly more oil than stock, so be sure to check your dipstick after an oil change.
