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.
