Source: 2020 Ram Heavy Duty Specifications (Stellantis media site).

No EPA fuel-economy rating. Heavy-duty pickups, chassis cabs and full-size vans above 8,500 lb gross vehicle weight are exempt from EPA labeling, so there is no official MPG figure for the 2500.

2020 Ram 2500 wheels & tires

The spec sheet doesn't list tire sizes for this model year; here is what the owner's manual says.

Cold tire pressure
Not a single number: the owner's manual refers to the tire and loading placard, which lists the pressures for your exact tire size and load.
Spare
The manual covers a compact spare or a non-matching full-size spare, depending on equipment; neither has a pressure sensor.
Lug nut torque
130 ft-lb (176 N·m) (Cone type), M14 x 1.50 thread, 22 mm socket
Pressure monitor
A tire pressure monitoring system warns when a tire is low.

Sizes and pressures vary by trim, wheel package and load: check the placard on your vehicle and the tire sidewall. Sizes from the manufacturer's specification sheet (2020 Ram Heavy Duty Specifications). Pressure and spare notes from the owner's manual.

2020 Ram 2500 maintenance schedule

The factory schedule for normal driving. Oil changes follow the oil-change indicator on most models; severe use (towing, dusty roads, lots of idling) shortens some intervals.

Schedule

A dot means the service is due at that mileage or after that many years, whichever comes first.

Additional Inspections

  • Inspect the CV/Universal joints
  • Inspect front suspension, tie rod ends, and replace if necessary
  • Inspect the front and rear axle surfacesIf gear oil leakage is suspected, check the fluid level. If using your vehicle for police, taxi, fleet, off-road or frequent trailer towing, change axle fluid.
  • Inspect the brake linings, replace as necessary
  • Adjust parking brake as necessary

Additional Maintenance

  • Replace cabin air filter

Additional Maintenance
Replace cabin air filter
Replace engine air cleaner filter
Replace spark plugsThe spark plug change interval is mileage based only, yearly intervals do not apply.
Flush and replace the engine coolant at 10 years or 150,000 miles (240,000 km) whichever comes first
Inspect the transfer case fluid, change for any of the following: police, taxi, fleet, or frequent trailer towing
Change the transfer case fluid
Inspect and replace PCV valve if necessary

At every oil change

  • Change oil and filter
  • Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on
  • Inspect battery and clean and tighten terminals as required
  • Inspect the CV/Universal joints
  • Inspect brake pads, shoes, rotors, drums, hoses and parking brake
  • Inspect engine cooling system protection and hoses
  • Inspect exhaust system
  • Inspect engine air cleaner if using in dusty or off-road conditions. If required, replace air cleaner filter
  • Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme dusty conditions

2020 Ram 2500 owner's manuals & publications

The manufacturer's owner's manual, quick guides, radio manuals, supplements and warranty booklets for the 2020 model year.

Salt, snow and hills: the data

Reading the 2020 2500 data for Great Lakes roads

We read the 2020 2500 owner data, service schedule and spec sheets with Michigan driving in mind: frozen starts, salted highways, cratered streets and hills. These are the figures worth acting on.

Oil for a frozen-driveway start

The fluids table calls for SAE 0W-40 (6.4L gas) and SAE 10W-30 or 5W-40 by temperature (6.7L diesel) at 7 qt (6.4L) and 12 qt (6.7L Cummins Turbo Diesel), with synthetic oil in the specification. Synthetic stock copes with both ends of this region's weather, from a subzero start in the Upper Peninsula to a loaded summer climb in the Smokies. Match the exact specification on the filler cap, not just the viscosity.

Battery checks before the cold

The spec sheet lists 730 cold-cranking amps. A 2500 left at a lake cottage or in a pole barn for weeks slowly drains its battery, and a cold snap then finds it with nothing to spare. A plug-in maintainer for stored vehicles is cheap insurance in the Great Lakes states.

Which wheels do the pulling

Factory drive configurations for 2020: rear-wheel drive and four-wheel drive. The same trim name can come with more than one drive system, so on a used 2500 confirm it from the window sticker or a VIN decode rather than the badge. In west Michigan, where lake-effect bands can pile up several inches of snow in an hour, driving both axles is what gets a loaded vehicle up an icy driveway.

Towing to the lake

Peak trailer rating this year: 19,680 lb, for one configuration in the towing chart. On Appalachian grades the descent is the harder half of the trip: drop to a lower gear so the engine holds speed, and save the brakes for stopping. The I-24 grade at Monteagle in Tennessee and the long climbs on the West Virginia Turnpike both punish a heavy trailer. Frequent towing also calls for axle fluid, transfer case fluid and automatic transmission fluid service.

Diesel through a Great Lakes winter

Cold-fuel guidance in the owner data: below 20°F (-7°C) use climatized No. 2 or blend with No. 1 ULSD. Paraffin in summer-grade diesel clouds as it chills and can plug the fuel filter, and a Great Lakes January gets cold enough for that. High-volume truck stops turn over fuel quickly, so buying there in winter improves the odds of a properly winterized blend. The DEF tank holds 5.7 gal.

Gravel hollow roads and the air filter

The schedule asks for more frequent air-filter attention in dusty conditions, beyond the normal replacement every 30,000 miles. Gravel roads up Appalachian hollows and coal-haul routes in West Virginia and eastern Kentucky qualify, so inspect the filter at each oil change if they are part of your week.

Data behind these notes: owner's manual capacities, the Mopar service schedule and factory spec sheets. Regional advice is general, written for drivers from Michigan to Ohio.

2020 Ram 2500 questions

How much oil does the 2020 Ram 2500 take?

With a filter change: 6.4L engine, 7 qt / 6.6 L and 6.7L Cummins Turbo Diesel engine, 12 qt / 11.4 L. Capacities are from the owner's manual; check the dipstick or oil-life display after filling.

What kind of oil does the 2020 Ram 2500 use?

6.4L gas engine: SAE 0W-40 full synthetic, API SN (Pennzoil Ultra 0W-40 or equivalent), all operating temperatures (MS-12633); 6.4L gas engine: Mopar brand oil filter; 6.7L diesel engine, ambient above 0°F (-18°C): SAE 10W-30, API CK-4 required (Mopar, Shell Rotella, Shell Rimula or equivalent); Cummins CES 20081 products also acceptable (MS-10902); 6.7L diesel engine, ambient below 0°F (-18°C): SAE 5W-40 synthetic, API CK-4 required (Mopar, Shell Rotella, Shell Rimula or equivalent) (MS-10902); and 6.7L diesel engine: Mopar oil filter.

When is the first scheduled maintenance on the 2020 Ram 2500?

At 20,000 miles or 2 years: inspect the cv/universal joints; inspect front suspension, tie rod ends, and replace if necessary; inspect the front and rear axle surfaces. if gear oil leakage is suspected, check the fluid level. if using your vehicle for police, taxi, fleet, off-road or frequent trailer towing, change axle fluid; inspect the brake linings, replace as necessary; adjust parking brake as necessary; replace cabin air filter. Oil changes in between follow the oil-change indicator.

Where can I find the 2020 Ram 2500 owner's manual?

The manufacturer publishes it free on Mopar.com as a PDF (linked in the manuals section above), along with quick guides, radio manuals and the warranty booklet.

What MPG does the 2020 Ram 2500 get?

The EPA doesn't publish a fuel-economy rating for the 2500: heavy-duty pickups, chassis cabs and full-size vans above 8,500 pounds gross vehicle weight are exempt from fuel-economy labeling, so there is no official MPG figure to quote.

What changed on the 2020 Ram 2500?

New option packages: Tradesman Level 1 Equipment Group, Tradesman Level 2 Equipment Group, Big Horn Level 1 Equipment Group, Power Wagon Level 1 Equipment Group and 3 more; Package no longer offered: Night Appearance Package; Newly available: Uconnect 12-in. radio (Big Horn/Lone Star) and Uconnect 8.4 AM/FM/Bluetooth/SiriusXM Radio (Tradesman); No longer standard or offered on some trims: Uconnect 8.4 AM/FM/Bluetooth/SiriusXM Radio/NAV/HD/CELL (Limited).

Does the 2020 Ram 2500 have recalls?

NHTSA lists 10 safety recall campaigns for the 2020 Ram 2500. The most recent: Air bags: side/window (January 2025), Structure: body (December 2022), and Power train: automatic transmission (November 2022). NHTSA's data was last fetched November 8, 2026. Recalls are listed by model year, so a given vehicle may or may not be covered: enter its VIN at nhtsa.gov/recalls or ask a dealer to see which are open.

What are the most common safety complaints about the 2020 Ram 2500?

Owners have filed 162 complaints about the 2020 Ram 2500 with NHTSA. The components named most often are fuel/propulsion system (40), engine (33), and diesel (30). 5 complaints involved a crash and 4 complaints a fire. Complaints are reports from owners that NHTSA does not verify, so treat them as a signal to look into, not a finding.

What is the 2020 Ram 2500's NHTSA crash-test rating?

NHTSA's overall 5-Star Safety Rating for the 2020 Ram 2500 is 4 out of 5 stars (Ram 2500 Crew PU/CC 4WD: 4 and Ram 2500 Crew PU/CC 2WD: 4). The rating combines frontal, side and rollover tests.

Specifications come from the manufacturer's spec comparison and its media-site specification sheets; maintenance schedules, fluids and publications come from Mopar's owner site and owner's manuals. Equipment and ratings vary by configuration; check the owner's manual or a dealer for a specific vehicle.
