How Ram schedules service: Oil Change Indicator
Ram trucks use the Oil Change Indicator system to signal oil service based on driving conditions. The Ram 1500 (HEMI 5.7L, eTorque mild-hybrid, EcoDiesel 3.0L) and Ram 2500/3500 (Cummins 6.7L turbo-diesel) have markedly different intervals — the schedule below covers Ram 1500 gas. Cummins-equipped HD trucks have separate oil, fuel filter, and DEF service requirements.
Essential maintenance
Critical for safety and preventing major damage
Engine Oil & Filter
Every 8,000 miHEMI 5.7L: SAE 5W-20 every 8,000 miles per Oil Change Indicator. Pentastar 3.6L: SAE 0W-20. EcoDiesel 3.0L: full synthetic 5W-30, every 10,000 miles. Cummins 6.7L (HD): 15W-40 every 15,000 miles or 6 months.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Tire Rotation
Every 8,000 miRotate tires every 8,000 miles. 4WD models towing or hauling regularly: rotate every 5,000 miles to even out drivetrain wear.
Estimated cost — typical U.S. ranges
Dealer

Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Brake Inspection
Every 8,000 miInspect pads, rotors, and parking brake every 8,000 miles. Ram 1500 front pads typically last 40,000-60,000 miles under normal use; cut by 30-50% if towing heavily.

Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Fuel Filter (EcoDiesel + Cummins)
Every 30,000 miEcoDiesel 3.0L: dual fuel filters (under hood + frame-mounted) replace every 30,000 miles. Cummins 6.7L: replace at 30,000 miles or sooner if water-in-fuel light triggers.
Estimated cost — typical U.S. ranges
Dealer
~$195–$250
Shop
~$135–$175
DIY
~$20–$60
On many modern cars the filter lives inside the fuel tank and is lifetime — verify before paying for a 'service'.
Important maintenance
Keeps your vehicle running smoothly and efficiently
Engine Air Filter
Every 40,000 miReplace engine air filter every 40,000 miles. Trucks driven on construction sites or unpaved roads should inspect at every oil change.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Automatic Transmission Fluid (ZF 8HP70 / 8HP75)
Every 60,000 miSevere service (towing, plowing): replace ATF every 60,000 miles. Normal: 120,000 miles. Use Mopar ATF+4 — substitutes cause harsh 3-4 and 5-6 shifts.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Transfer Case Fluid (4WD)
Every 60,000 miRam 1500 4WD: replace transfer case fluid every 60,000 miles. Use Mopar ATF+4 for the BorgWarner 44-44 transfer case.
Estimated cost — typical U.S. ranges
Dealer
~$105–$140
Shop
~$75–$100
DIY
~$15–$40
AWD/4WD vehicles only. Easy drain-and-fill on most platforms.
Differential Fluid (front + rear)
Every 60,000 miFront and rear axle fluid: replace every 60,000 miles, or 30,000 miles if towing 6,000+ lbs regularly. Limited-slip rears require Mopar friction-modifier additive.
Estimated cost — typical U.S. ranges
Dealer
~$150–$195
Shop
~$105–$135
DIY
~$20–$50
Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.
Spark Plugs (HEMI — 16 plugs)
Every 100,000 miHEMI 5.7L runs two spark plugs per cylinder (16 total) — replace at 100,000 miles. Pentastar 3.6L: standard 6 plugs at 100,000 miles. EcoDiesel: glow plug inspection at 100,000.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275
DIY
~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
MS-12106 Coolant (Mopar HOAT)
Every 50,000 miMopar HOAT (purple): first change at 100,000 miles or 5 years, then every 50,000 miles. EcoDiesel uses a different OAT formulation — do not mix.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
