Oil Maintenance & Service Tips
Check the Jeep Gladiator engine oil level on level ground, after the engine has been shut off and allowed to drain back for several minutes. Use the dipstick as the final reference, even when filling to the published engine oil capacity.
For most Gladiator models using synthetic oil, a normal oil change interval is between 7,500 and 10,000 miles or about 12 months, with 10,000 miles as the maximum recommended limit. Under towing, off-road use, dusty roads, or frequent short trips, many guidance documents suggest shortening the maintenance interval to around 5,000 miles.
Always replace the oil filter at every oil change, since proper oil filter replacement is essential for holding contaminants and maintaining flow during the full interval. Tighten the oil drain plug to the specified torque for gasoline or diesel engines rather than guessing by feel to protect the oil pan and gasket.
Normal vs severe driving conditions
| Driving Condition | Suggested Oil Change Interval |
|---|---|
| Normal driving, mixed city and highway, light loads | 7,500 to 10,000 miles or 12 months with synthetic oil |
| Severe driving, frequent towing, off-road, dusty or very hot use | Around 5,000 miles or less, while never exceeding 10,000 miles or 12 months |
FAQs
What kind of oil does a Jeep Gladiator use?
Gasoline Jeep Gladiator models with the 3.6L Pentastar V6 require full synthetic SAE 0W-20 oil that meets FCA MS-6395. EcoDiesel 3.0L Gladiator models use full synthetic SAE 5W-40 oil that meets the FCA MS-12991 diesel specification or equivalent.
How much oil does a Jeep Gladiator take?
Most Jeep Gladiator trucks with the 3.6L V6 hold about 5.0 qt (4.7 L) of engine oil with a new filter. Gladiator models equipped with the 3.0L EcoDiesel V6 require approximately 9.0 qt (8.6 L) with filter.
What is the recommended oil type for a Jeep Gladiator?
For 3.6L gasoline engines, use a high quality full synthetic 0W-20 that is API certified and specifically approved to FCA MS-6395. For 3.0L EcoDiesel engines, use a full synthetic 5W-40 oil that meets the FCA MS-12991 or equivalent European diesel specification.
What is the oil change interval for a Jeep Gladiator?
With modern synthetic oil and the factory oil life monitor, many Jeep Gladiator references specify 7,500 to 10,000 miles or about 12 months, with 10,000 miles as an upper limit. Under severe use such as heavy towing or off-road driving, shortening the oil change interval to around 5,000 miles helps maintain engine protection.
What is the oil drain plug torque on a Jeep Gladiator?
For 3.6L Pentastar V6 Gladiator models, the engine oil drain plug torque is about 20 lb-ft, which equals roughly 27 N·m. For 3.0L EcoDiesel Gladiator trucks, the recommended drain plug torque is about 33 lb-ft, or around 45 N·m.
Conclusion
Across all current Jeep Gladiator model years, the 3.6L gasoline engine uses about 5.0 qt of full synthetic 0W-20, while the 3.0L EcoDiesel uses about 9.0 qt of full synthetic 5W-40. Following the manufacturer approved oil type, viscosity, capacity, and drain plug torque is important for reliable lubrication and long term durability. Regular oil and filter changes within the specified maintenance interval help keep the Jeep Gladiator engine operating correctly under both normal and severe driving conditions.
