2018 Ram 1500 maintenance schedule

The factory schedule for normal driving. Oil changes follow the oil-change indicator on most models; severe use (towing, dusty roads, lots of idling) shortens some intervals.

A dot means the service is due at that mileage. Engines: see schedule title.

Service20k30k40k50k60k70k80k90k100k110k120k130k140k150k
Additional Inspections
Inspect the CV/Universal joints.
Inspect front suspension, tie rod ends, and replace if necessary.
1500 Models:Inspect the front and rear axle surfaces. If gear oil leakage is suspected, check the fluid level. If using your vehicle for police, taxi, fleet, off-road or frequent trailer towing, change axle fluid.
2500/3500 Models:Inspect the front and rear axle surfaces. If gear oil leakage is suspected, check the fluid level. If using your vehicle for police, taxi, fleet, off-road or frequent trailer towing, change axle fluid.
Inspect the brake linings, replace as necessary.
Adjust parking brake as necessary.
Inspect transfer case fluid.
Additional Maintenance
Replace cabin air filter.
Replace engine air filter.
Replace spark plugs.
Flush and replace the engine coolant at 10 years or 150,000 miles (240,000 km) whichever comes first.
Change automatic transmission fluid and filter(s) (six-speed automatic only), if using your vehicle for police, taxi, fleet, or frequent trailer towing.
Change automatic transmission fluid and filter(s) (six-speed automatic only).
Inspect the transfer case fluid, change for any of the following: police, taxi, fleet, or frequent trailer towing.
Change the transfer case fluid.
Inspect and replace PCV valve if necessary.

At Every Oil Change Interval As Indicated By Oil Change Indicator System

  • Change oil and filter.
  • Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
  • Inspect battery and clean and tighten terminals as required.
  • Inspect automatic transmission fluid if equipped with dipstick.
  • Inspect brake pads, shoes, rotors, drums, hoses and park brake.
  • Inspect engine cooling system protection and hoses.
  • Inspect exhaust system.
  • Inspect engine air cleaner if using in dusty or off-road conditions.
  • Lube the front drive shaft fitting (2500/3500 (4x4) models only).
