Oil Change Interval

The 2020 Ram 1500 is equipped with an automatic oil change indicator system. The system will display a message in the instrument cluster when it's time for a service. However, the interval should never exceed one year or 10,000 miles.

• Normal Duty: Follow the oil life monitor, which typically recommends an oil change every 7,500 to 10,000 miles. This assumes primarily highway driving in moderate conditions.
• Severe Duty: Change the oil and filter every 3,500 to 4,000 miles. Severe duty operation includes frequent short trips, driving in dusty or very hot/cold conditions, and towing or hauling heavy loads.

Drain Plug Torque

Properly tightening the oil drain plug is critical to prevent leaks.

• Drain Plug Torque Spec (both engines): 25 ft-lbs (34 Nm).
• Crush Washer / Gasket: The drain plug has a rubber gasket that should be inspected at every oil change and replaced if it shows any signs of cracking, hardening, or damage. A leaking drain plug is most often caused by a faulty gasket.

How to Change the Oil (Simplified)

1. Warm Up: Run the engine for 2-3 minutes to warm the oil.
2. Position & Drain: Safely raise the truck and place a drain pan under the oil pan. Remove the 13mm (for 5.7L) or 1/2-inch (for 3.6L) drain plug and let the oil drain completely.
3. Replace Filter:
   • For the 5.7L Hemi: The filter is a standard spin-on canister located on the side of the engine block. Unscrew it, apply a light coat of new oil to the gasket of the new filter, and screw it on until it's hand-tight, plus an additional quarter-turn.
   • For the 3.6L V6: The filter is a cartridge element located in a housing on top of the engine, near the firewall. Use a 24mm socket to unscrew the plastic cap. Remove the old cartridge and the old O-ring from the cap. Lube the new O-ring (included with the new filter) with fresh oil and install it on the cap. Insert the new cartridge into the housing and torque the cap to 18 ft-lbs (25 Nm).
4. Reinstall & Fill: Clean the drain plug and surrounding area. Reinstall the drain plug and tighten it to spec. Lower the vehicle and fill with the correct amount and type of new oil.
5. Check & Reset: Start the engine, let it run for 30 seconds, then shut it off. Wait a minute for the oil to settle, then check the dipstick and top off if necessary. Finally, reset the oil life monitor through the vehicle's infotainment screen.

Common Issues & Tips for This Generation

• 3.6L V6 Filter Housing: The most common mistake on the Pentastar V6 is forgetting to replace the large O-ring on the filter housing cap or improperly seating it. This will cause a significant oil leak. Always use the new O-ring that comes with your new filter cartridge.
• 5.7L Hemi "Hemi Tick": While often related to valvetrain components, using the correct specification oil (MS-6395) and weight (5W-20) is critical for the proper function of the hydraulic lifters and Variable Valve Timing (VVT) system. Using a heavier oil can impede performance and may not provide adequate lubrication on startup.
• Oil Life Monitor: Always reset the oil life monitor after a service. Failure to do so will result in inaccurate service reminders.
