Generally, Jeep recommends using oils meeting the following specifications:
* Viscosity: This will be something like 5W-20, 5W-30, or even 0W-20, depending on your climate and the recommendations in your owner's manual. Colder climates generally call for lower viscosity (like 0W-20 or 5W-20), while warmer climates might suggest a higher viscosity (like 5W-30).
* API Certification: Look for an oil with an API certification, such as SN Plus, SP, or SN. Newer certifications generally indicate improved performance and protection.
* Manufacturer's Specifications: The owner's manual may specify brands or types of oil that are explicitly recommended for optimal performance and engine longevity.
Don't rely solely on online advice. Using the wrong oil can severely damage your engine. Always consult your owner's manual for the precise recommendations.
