2015 RAM 2500 Oil Type and Capacities

The 2015 RAM 2500 has three engine options available in the family. The 5.7 L and 6.4 L engine takes 7q of 5W-20 and 0W-40 respectively. The 6.7 L diesel engine takes 12 q of 15W-40.

Below are the oil types and capacities for each engine. You will also find the recommended oil filters for each engine.

	Oil Type	Oil Capacity	Oil Filter
5.7 L Hemi	5W-20	7 q (6.6 L)	Mopar – 4892339AB
6.4 L Hemi	0W-40	7 q (6.6 L)	Mopar – 4892339AB
6.7 L Diesel	15W-40	12 q (11.4 L)	Mopar – 5083285AA

For the Mopar filters, if they are not available, a filter should only be used that meets or exceeds SAE/USCAR-36 Filter Performance Requirements.

All the products listed below, however, come from the Mopar Amazon shop.

I found the recommendations for the oil type and capacities from the 2015 RAM 2500 owners manual, and 2015 6.7 L Ram 2500 Diesel Supplement but found the oil filter type recommendations from the Mopar Store.

5.7 L HEMI V8 Engine

The 2015 5.7 L HEMI V8 engine in the RAM 2500 takes 7 quarts of 5W-20 Penzzoil or Shell Helix oil and uses the Mopar 04892339AB oil engine filter.

When operating with a total combined weight over 14,000 lbs, 5W-30 oil is recommended instead.

6.7 L Diesel Engine

The 2015 6.7 L diesel engine in the RAM 2500 takes 12 quarts of 15W-40 oil and uses the Mopar 5083285AA oil engine filter. Preferred brands are Mopar, Shell Rotella, and Shell Rimula engine oils.

For operating under 0 degrees F, full synthetic 5W-40 (Mopar, Shell Rotella, and Shell Rimula) should be used instead.

How often should you change your oil?

According to the 2015 RAM 2500 owner’s manual, there is no specific time or mileage that should schedule a routine oil change.

There is a built-in oil change indicator system that will alert you when it is time for a scheduled maintenance.

The 6.4 L gas engine should never exceed an oil change passed 8,000 miles or 12 months between them. After the “oil change required” message, servicing should be completed within 500 miles.

RAM does mention that oil changes should never exceed 15,000 miles or 6 months between them.

Every time you perform an oil change you should also:

• replace the filter
• rotate your tires
• inspect battery
• inspect CV/Universal joints
• check transmission fluid
• check brake parts
• inspect exhaust system
• inspect engine cooling system and hoses
• check air filter
• inspect axle and steering components
