However, generally speaking, for a 2000 Jeep Cherokee Sport, you'll likely find that it recommends a conventional or synthetic blend motor oil meeting the following specifications:
* API Service Classification: Likely something like SF, SG, SH, SJ, or SL (check your manual for the most current recommendation). Modern oils generally meet multiple classifications.
* Viscosity (weight): This will be something like 5W-30, 10W-30, or possibly others depending on your climate and engine. Again, your owner's manual is the definitive source.
Using the wrong oil viscosity can damage your engine. Using the wrong API classification can also lead to problems. Always consult your owner's manual for the specific recommendations for your vehicle.
