2018 RAM 1500 Oil Type and Capacities

The 2018 RAM 1500 has three engine options available in the family.

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 V8 HEMI	5W-20	7 q (6.6 L)	Mopar 04892339AB
3.6 L V6 Pentastar	5W-20	6 q (5.6 L)	Mopar 68191349AC
3.0 L Ecodiesel	5W-40	10.6 q	Mopar 6229402AA

RAM 1500 recommends that you use Mopar approved products for both the oil and filters listed below.

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 2018 RAM 1500 owners manual, but found the oil filter type recommendations from the Mopar Store.

*Amazon didn’t list the Mopar 68492616AA filter, but this is the previous model which the new filter replaces. Click the mopar link if you want to buy the newest model.

How often should you change your oil?

According to the 2018 RAM 1500 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. It recommends that you get your oil changed and serviced within 500 miles of the warning.

RAM does mention that oil changes should never exceed 10,000 miles or 12 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
