    Severe-duty schedule

    If your 2018 Ram ProMaster operates under severe conditions, specific maintenance intervals need to be adjusted. Severe duty is generally defined as:

    • Towing or heavy hauling: Places increased strain on the engine, transmission, and brakes.
    • Driving in dusty or sandy conditions: Accelerates the wear on air filters and can contaminate engine oil more quickly.
    • Frequent short trips (under 10 miles) or extensive idling: Prevents the engine from reaching optimal operating temperature, leading to moisture buildup in the oil.
    • Driving in extremely cold climates: Can put extra stress on the battery, engine, and cooling system.
    • Stop-and-go city driving: Increases wear and tear on brakes and transmission.

    For vehicles operating under severe conditions, consider the following adjustments:

    • Oil and filter changes: Every 3,000-4,000 miles or every 3 months, whichever comes first.
    • Engine and cabin air filters: Inspect more frequently and replace as needed, potentially every 10,000-15,000 miles.
    • Transmission fluid and filter service: Every 30,000-40,000 miles.
    • Brake fluid flush: Every 2 years or 30,000 miles.
    • Differential fluid service: Every 30,000 miles.
    • Spark plugs: Depending on engine type and usage, consider replacing at 45,000-60,000 miles.
    • Fuel filter: While a
