2021 Ram Promaster Cargo Van Oil Change: Specs & Service

The service is designed for the 3.6-liter V6 engine used across the 2021 Ram Promaster Cargo Van lineup. The old oil is drained before the specified replacement oil is added, and the visit is logged against the vehicle’s history at Larry H. Miller Dodge Ram Peoria in Peoria.

• Drain and refill with the specified oil grade and capacity
• Install a new oil filter
• Reset the oil-life monitor and check underhood fluids

Fresh oil helps the 3.6-liter V6 manage heat and suspended contaminants during commercial driving. A driver may first notice an oil-change reminder, mileage beyond the last service, dark or low oil on the dipstick, or a ticking and louder engine note at startup.

• Oil degrades through heat and use
• Dark or low dipstick oil can signal attention is needed
• Service history helps document completed maintenance

The reminder is one of several signs that service may be due. Drivers should also pay attention to mileage since the last visit, the dipstick level and appearance, and changes in engine sound at startup. Larry H. Miller Dodge Ram Peoria can reset the monitor after completing the oil service.

• Schedule service when the reminder appears
• Check the dipstick for level and condition
• Have the oil-life monitor reset after service
