What kind of oil for 1998 jeep Cherokee?

The type of oil for a 1998 Jeep Cherokee depends on the engine it has. There were several engine options available that year. To know for sure, you need to check your owner's manual. It will specify the recommended oil type (viscosity and type – conventional, synthetic blend, or full synthetic) and the oil capacity.

However, generally speaking, for a 1998 Jeep Cherokee, you'll likely find recommendations for:

* SAE 5W-30: This is a common viscosity grade for many vehicles, including those from that era. It's often a good starting point if you don't have the owner's manual.

* Conventional, Synthetic Blend, or Full Synthetic: The owner's manual will tell you which is preferred or acceptable. Full synthetic is generally more expensive but offers better protection and longer life. Conventional oil is the least expensive option.

Crucially, consult your owner's manual. Using the wrong type or viscosity of oil can damage your engine. Don't rely solely on internet advice; the information in your owner's manual is specific to your vehicle.
