Jeep, Dodge, Ram, and Chrysler oil change indicator and maintenance schedule explained
Jeep, Dodge, Ram, and Chrysler vehicles use an oil change indicator plus a mileage-based maintenance schedule. Here's how it works, what's due at each interval, and the severe-use schedule.
Your Ram's dashboard just displayed "Oil Change Required" with a chime. Or your Jeep Grand Cherokee is showing a maintenance notification. You know it has something to do with service, but what else does the car need beyond an oil change?
This post is part of our complete guide to vehicle maintenance systems, covering every major manufacturer sold in the US.
Stellantis vehicles — that's the parent company behind Jeep, Dodge, Ram, and Chrysler — use an Oil Change Indicator System paired with a mileage-based maintenance schedule. The oil indicator is algorithm-driven, similar to what GM and Ford use, but the broader maintenance items follow a traditional printed schedule in the owner's manual. Here's how the whole system works.
The Oil Change Indicator System
Most modern Jeep, Dodge, Ram, and Chrysler vehicles come equipped with an oil change indicator that monitors driving conditions and calculates when the oil needs replacing. It's not just a mileage counter — it analyzes oil quality data, engine operating conditions, fuel ethanol level, and driving patterns.
When it determines the oil needs changing, the message "Oil Change Required" appears on the Driver Information Display (DID) along with an audible chime.
The system accounts for severe driving conditions. If you're doing a lot of short trips, towing frequently, driving in extreme temperatures, or running E85 fuel, the system will trigger the oil change message earlier. Under severe conditions, the indicator can trigger as early as 3,500 miles. Under normal to moderate driving, it typically comes on between 7,500 and 10,000 miles.
General oil change intervals by driving style
- Light everyday driving, mostly highway: 7,500-10,000 miles
- Mixed driving with moderate loads: 5,000-8,000 miles
- Heavy towing, off-roading, extreme temperatures, frequent short trips: 3,000-5,000 miles
- Maximum interval regardless of conditions: 10,000 miles or 12 months
After the oil change is completed, the indicator needs to be reset. Your shop or dealership handles this at the time of service.
The broader maintenance schedule
The oil indicator only handles oil. Everything else follows Stellantis's mileage and time-based maintenance schedule. This is where the real work comes in, because these vehicles have a detailed set of service items that come due at specific intervals.
The exact schedule varies by model, engine, and year, but here's the general framework that applies across most Jeep, Dodge, Ram, and Chrysler gas-engine vehicles:
Every oil change interval (per the oil indicator)
- Engine oil and filter change
- Tire rotation
- Brake inspection
- CV/Universal joint inspection
Every 20,000 miles
- Everything above, plus:
- Inspect front suspension and tie rod ends
- Inspect brake linings (replace if needed)
- Replace cabin air filter (some models list this at 12,000 miles)
- Inspect exhaust system
Every 30,000 miles
- Everything above, plus:
- Replace engine air cleaner filter
- Inspect front and rear axle surfaces for leaks
- Inspect transfer case fluid (4WD/AWD models)
- Change axle fluid if used for police, taxi, fleet, or frequent towing
- Inspect CV/Universal joints
Every 60,000 miles
- Everything above, plus:
- Replace spark plugs (2.0L and some 4-cylinder engines)
- Inspect accessory drive belt
- Change automatic transmission fluid and filter if used for police, taxi, fleet, off-road, or frequent towing (many models list this as an "if applicable" item based on use)
Every 100,000 miles
- Everything above, plus:
- Replace spark plugs (3.6L Pentastar V6, 5.7L Hemi V8)
- Inspect and replace PCV valve if needed
- Replace accessory drive belt
Every 150,000 miles (or 10 years)
- Flush and replace engine coolant (first replacement — subsequent every 5 years or 100,000 miles)
Model-specific notes
Ram 1500/2500/3500: Trucks that tow or haul regularly fall into the "severe" category for oil changes. Transfer case fluid, front and rear differential fluid, and transmission fluid all need attention sooner under heavy use. If you tow, don't wait for the standard intervals.
Jeep Wrangler and Gladiator: Off-roading puts extra stress on every fluid and component. Dust, water crossings, and aggressive terrain use means air filters, axle fluids, and transfer case fluid may need service more frequently than the standard schedule suggests.
Jeep Grand Cherokee: The cabin air filter is due every 12,000 miles on many Grand Cherokee models. If you live somewhere with high pollen or particulate levels, this one matters for your AC performance and the air quality inside the car.
Dodge Charger, Challenger, and Durango with Hemi V8: The 5.7L Hemi uses MDS (Multi-Displacement System), and clean oil with the correct specification is important for the system to function properly. Spark plugs are due at 100,000 miles.
Chrysler Pacifica: The Pacifica's maintenance schedule includes additional items for the plug-in hybrid (PHEV) version, including hybrid-specific coolant and battery system checks.
Diesel models (Ram with Cummins): Diesel maintenance includes fuel filter changes, diesel exhaust fluid (DEF) refills, and diesel-specific oil meeting the correct specification. The oil change indicator accounts for diesel operating conditions.

FAQ
What does "Oil Change Required" mean on my Jeep, Dodge, or Ram? It means the vehicle's Oil Change Indicator System has determined your engine oil needs replacing based on driving conditions. It factors in engine operation, temperature, fuel type, and driving patterns. It's not just a mileage counter — it adjusts based on how you use the vehicle.
How often does a Ram 1500 need an oil change? It depends on driving conditions. Light highway driving: 7,500-10,000 miles. Mixed driving with some towing: 5,000-8,000 miles. Heavy towing or severe conditions: 3,000-5,000 miles. The oil change indicator on the dash calculates the optimal interval for your specific use. Maximum is 10,000 miles or one year.
Does the oil change indicator on a Jeep track other maintenance items? No. The indicator only monitors engine oil. All other maintenance items — cabin filter, engine air filter, transmission fluid, brake fluid, coolant, spark plugs — follow a mileage and time-based schedule in your owner's manual.
When should I change the transmission fluid in my Ram truck? For normal driving, many Ram models don't list a specific transmission fluid interval under the standard maintenance schedule. However, if you use the truck for towing, off-roading, or fleet/commercial purposes, Stellantis recommends changing the automatic transmission fluid and filter every 60,000 miles. Many mechanics recommend proactive fluid changes even under normal use.
What maintenance does a Jeep Wrangler need at 30,000 miles? At 30,000 miles, a Wrangler typically needs an oil and filter change, tire rotation, engine air filter replacement, cabin air filter check, front suspension and tie rod inspection, brake lining inspection, transfer case fluid inspection, axle inspection, and CV joint inspection. If you off-road regularly, some of these items may need attention sooner.
When do I replace spark plugs on a Hemi engine? The 5.7L Hemi V8 has a 100,000-mile spark plug replacement interval. The 3.6L Pentastar V6 is the same. Smaller 4-cylinder engines like the 2.0L turbo typically need spark plugs at 60,000 miles. Check your owner's manual for the exact interval for your engine.
How often should I change the coolant in my Chrysler or Dodge? First coolant replacement is at 150,000 miles or 10 years, whichever comes first. After that, it's every 100,000 miles or 5 years. Stellantis uses a long-life coolant formula, but the intervals should still be followed.
