* 10W-30 is often recommended as a good all-around weight for most temperatures. This is likely what the owner's manual will specify.
* 5W-30 can be used in colder climates.
* 20W-50 might be suitable for very hot climates or situations with heavy towing, but it's less common for this engine.
Always check your owner's manual for the specific recommendations from Jeep. The recommended weight may also depend on factors such as the condition of the engine and the type of driving you do. Using the wrong weight oil can damage your engine.
