The recommended weight of engine oil for a Jeep Wrangler with a 4.0L engine depends on several factors, including the ambient temperature and the specific year of the vehicle. However,
5W-30 is generally considered the most common and widely recommended weight for these engines, especially in moderate climates.
Consult your owner's manual for the *specific* recommendation for your Jeep Wrangler's year and model. The manual will provide the most accurate information based on your vehicle's design and operating conditions. Using the wrong weight oil can damage your engine.
