Oil Specifications of a Dodge Ram Cummins

by Qyou Stoval

Those who want more power than the standard 5.7L V-8 Dodge 2500 can choose to purchase the Dodge Ram Cummins instead. This turbo diesel pickup truck has 350hp with 600 lb-ft of torque. The Dodge is considered a heavy duty pickup truck, and as such must operate using the suitable oil to extend fuel economy and engine life. The ambient temperature in your location will also determine which type of oil you should purchase.

Oil Type

Purchase15W- 40 oil, which is suitable for most driving conditions. Ensure the oil has a dual rating of CF4/SH. 15W-40 oil can be found at your local auto parts store. If you choose to have a professional change your oil, they may have that brand in stock. If you reside in an environment that has a consistent temperature below 10°F, then use 10 W- 30 oil instead. Make sure it has an SF5/SG rating or better. For colder climates you can choose to purchase synthetic or synthetic blends, but know that once you switch to a synthetic oil you cannot go back to a conventional natural oil for your Dodge.

Oil Capacity

Depending on the year of your Dodge Cummins, it might be a slight difference in oil capacity. You can purchase more oil if you are short on the amount necessary for your Dodge. The 98-2000 Dodge Cummings requires an oil pan capacity of 2.5 gallons, which is 10 quarts or 9.46 L. Older model Dodge Cummins have 11-quart oil pan capacities. The 10-quart and 11-quart oil capacities also include an extra liter for your oil filter.

Oil Change Intervals

Dodge Cummins trucks that were manufactured between 1989 and 1998 with 12-valve engines should have the oil changed every 6,000 miles if driving under normal conditions, and changed every 3,000 miles if driving under heavy conditions. For vehicles 1998 and newer with 24-valve engines, the oil should be changed every 7,500 miles under normal driving conditions and every 3,750 miles under heavy, rigorous conditions.
