Jeep Gladiator Oil Change Specifications
The Jeep Gladiator is the only open-air 4x4 pickup, built on the Wrangler platform with a 5-foot bed. It uses the proven 3.6L Pentastar V6 across the lineup. Heavy-duty truck use plus Wrangler trail capability means timely oil service is essential. Our Mopar-certified team handles every Gladiator service with OEM-spec full synthetic oil.

Oil Change Tips for Your Jeep Gladiator
- Off-road driving in dust, mud, sand, or water counts as severe-duty — shorten intervals to 5,000-7,500 miles for trail-frequent Gladiators.
- Towing (Gladiator is rated up to 7,700 lbs) accelerates oil breakdown — change closer to 5,000-7,500 miles when towing regularly.
- After any deep water crossing, check engine oil for milky discoloration.
- Mojave and Rubicon owners should be especially diligent given the off-road duty cycle.
- Always use full synthetic — never substitute conventional oil.
What's Included in Every Oil Change at Mahon CDJR
Every oil change at Mahon CDJR includes a complimentary multi-point inspection performed by factory-trained Mopar technicians. We replace your oil and filter with the OEM-spec full synthetic oil your Jeep Gladiator requires, then check fluid levels, inspect battery and terminals, verify tire pressure and wear, and examine your brake pads. You leave with a complete snapshot of your vehicle's health — not just fresh oil.
Note on Pricing: Oil change cost varies by engine and oil type. Diesel and PHEV models often use specialty oils that affect pricing. Call (828) 492-2121 for a precise estimate for your specific Jeep Gladiator.
