About this vehicle
The 2015 Ram 2500 is a heavy-duty pickup truck manufactured by the Ram Trucks division of Stellantis (formerly part of Chrysler Group LLC/FCA US LLC). As part of the Ram Heavy Duty lineup, the 2500 series is designed to sit above the light-duty Ram 1500, offering increased towing and payload capacities suitable for commercial use or heavy-duty consumer tasks.
This specific model is equipped with a 6.7L diesel engine, which is part of the Cummins engine family. The relationship between Ram and Cummins is central to the identity of this truck, as the Cummins diesel powertrain is a hallmark of the Ram Heavy Duty series. Owners typically utilize these vehicles for high-torque applications, such as heavy towing, hauling large payloads, or long-distance work cycles.
Because these engines are designed for durability under load, they are subject to specific maintenance requirements regarding fuel filtration, air handling, and emission control systems. Regular inspections of cooling systems and drivetrain components are standard practice for maintaining these high-mileage vehicles. Specific engine code details like ‘L’ should be verified against the owner’s manual or VIN decoder.
Common questions about this vehicle’s diesel oil and maintenance
How much oil does my 6.7L Cummins take?
The 2015 Ram 2500 6.7L engine requires 12 quarts of oil when performing a service that includes a filter change.
