	Oil Type	Oil Capacity	Oil Filter
5.7 L V8 HEMI	5W-20	7 q (6.6 L)	Mopar 04892339AB
3.6 L Pentastar V6	5W-20	6 q (5.6 L)	Mopar 68191349AC

RAM 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 2021 RAM 1500 Classic owners manual, but found the oil filter type recommendations from the Mopar Store.

The 2021 5.7 L V8 HEMI engine in the RAM 1500 classic takes 7 quarts of 5W-20 full synthetic oil and uses the Mopar 04892339AB oil engine filter.

How often should you change your oil?

According to the 2021 RAM 1500 Classic 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
