The Jeep Gladiator maintenance schedule aligns with Stellantis factory guidelines, primarily using an Oil Change Indicator system. For standard gas engines, it's recommended to service within 500 miles of the reminder. Don't exceed 10,000 miles, 12 months, or 350 engine hours. Here in Globe, Arizona, many drivers will find themselves needing to follow the severe-service schedule due to local conditions.

Understanding Your Gladiator's Maintenance Schedule

Stellantis lays out maintenance based on this handy Oil Change Indicator. It tells you when it’s time for an oil change. You should definitely have it done within 500 miles of that alert. No matter what, never let it go beyond 10,000 miles, 12 months, or 350 engine hours with standard gas engines. If you have a 6.4L, RHO, or 6.2L engine, you’ll need to change the oil more often—every 6,000 miles or 6 months. For the Ram HD 6.7L Cummins, you’re looking at 15,000 miles or 12 months.

Normal Service Intervals

Under normal conditions, your Jeep Gladiator requires regular services at the following intervals:

Every oil change: Change oil and filter, check battery, CV/U-joints, brakes, cooling system, and exhaust. Don’t forget to rotate tires (Wrangler models should rotate every 10,000 miles).
Cabin air filter: Change every 12,000 miles.
Engine air filter: Change every 30,000 miles.
Spark plugs: Change at 100,000 miles for 3.6L and 5.7L engines (2.0L turbo engines need changing at 60,000 miles).
PCV valve: Check or replace at 100,000 miles.
Coolant: Change every 10 years or 150,000 miles.
Transfer case fluid: Change at 120,000 miles (note that Durango models need a drain and refill every 30,000 miles).

Why Globe Drivers Often Need Severe Service

A lot of Jeep Gladiator owners around Globe will find their driving habits and local climate call for the severe-service maintenance schedule. According to Stellantis, severe-service conditions include "desert driving, dusty or off-road conditions, frequent trailer towing, sustained high speed above 90°F, [and] extreme heat" (source: Chrysler, Dodge, Jeep and Ram owner's manuals at vehicleinfo.mopar.com). These conditions are pretty common in our area.

Think about these local factors:

Desert Driving and Extreme Heat: Globe gets really hot for much of the year, often pushing past 90°F. This heat stresses engine components and fluids.
Dusty or Off-Road Conditions: Many roads in Gila County are unpaved, creating plenty of dust. If you love off-roading, the Gladiator can handle it, but that kind of driving increases wear and tear.
Frequent Trailer Towing: The Jeep Gladiator is a favorite for towing everything from RVs to utility trailers. Regular towing adds extra strain on things like the powertrain, brakes, and cooling system.
Short Trips: Though not always listed as severe, frequent short trips where the engine doesn’t reach its optimal temperature can also lead to faster wear.

Severe-Service Schedule Changes

If your driving fits into these severe categories, keep these accelerated maintenance requirements in mind:

Axle fluid: Change every 30,000–40,000 miles for off-road, towing, fleet, police, or taxi use.
Transfer case fluid: Change at 60,000 miles and again at 120,000 miles for off-road, towing, fleet, police, or taxi use.
Engine air filter: Check at every oil change if you often drive in dusty or off-road conditions.
