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 ProMaster.

2021 Ram ProMaster 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: Depending on equipment the van has a regular-size spare, a compact spare or a tire service kit; the manual says the spare may not have a pressure sensor.
Lug nut torque: 145 ft-lb (197 N·m), M16 x 1.50 thread, 21 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 (2021 Ram ProMaster Specifications). Pressure and spare notes from the owner's manual.

2021 Ram ProMaster 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.

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

Great Lakes owner notes

What counts on a 2021 Ram ProMaster from Michigan to Tennessee

From the Snowbelt east of Cleveland to the ridges of West Virginia and east Tennessee, this part of the country throws salt, snow and grade at every vehicle. Here is how the 2021 Ram ProMaster specifications line up against all three.

What the manual says about oil

Oil capacity is 6 qt, and the manual lists SAE 5W-20. Where more than one engine appears in the lineup, the engine code on the window sticker settles which grade applies. The wrong one in a Tennessee winter gives up a little protection on every cold start, and over years of driveway starts that adds up.

Battery checks before the cold

The spec sheet lists 800 cold-cranking amps. A ProMaster 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.

Drive systems for lake-effect snow

This model year was built with front-wheel drive only. On an icy grade, smooth throttle beats wheelspin, and winter tires do more for a front-wheel drive vehicle than any other change. When lake-effect snow turns an interstate white in minutes, leave several car lengths more than usual and let the vehicles with driven wheels at both ends sort themselves out ahead of you.

Brake fluid, long descents and salted lines

The schedule lists brake fluid replacement starting at 20,000 miles. Brake fluid absorbs moisture over time, which lowers its boiling point, and a long descent off a Tennessee or West Virginia ridge is exactly where brakes get hot enough for that to matter. In Michigan and Ohio, have the steel brake lines checked for salt corrosion whenever the wheels are off.

Filters for dust and pollen

The cabin air filter first comes up at 20,000 miles. Spring pollen in the Ohio and Tennessee valleys is heavy, and a clogged cabin filter also slows the defroster in winter because it chokes the blower's airflow. It is a five-minute job on most vehicles.

Fuel grade and winter reserve

Fuel requirement: 87 octane. In winter, keeping the tank above half is a sensible habit across the Great Lakes states, because lake-effect pileups and mountain snow on I-64 or I-77 can leave traffic stopped for hours, and fuel is your heat.

Specifications are the manufacturer's; the weather and road context is ours. When a note here and the 2021 owner's manual disagree, follow the manual.

2021 Ram ProMaster questions

How much oil does the 2021 Ram ProMaster take?

With a filter change: 3.6L engine, 6 qt / 5.6 L. Capacities are from the owner's manual; check the dipstick or oil-life display after filling.

What kind of oil does the 2021 Ram ProMaster use?

Engine oil: SAE 5W-20, API certified (MS-6395) and Engine oil filter: Meets or exceeds SAE/USCAR-36 filter performance requirements (SAE/USCAR-36).

When is the first scheduled maintenance on the 2021 Ram ProMaster?

At 20,000 miles or 2 years: inspect the cv/universal joints; inspect front suspension, tie rod ends, boot seals, and replace if necessary; inspect the brake pads, replace as necessary; inspect the cabin air filter, replace as necessary; replace the brake fluid every two years. the brake fluid change interval is time based only, mileage intervals do not apply. Oil changes in between follow the oil-change indicator.

Where can I find the 2021 Ram ProMaster 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 2021 Ram ProMaster get?

The EPA doesn't publish a fuel-economy rating for the ProMaster: 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.

Does the 2021 Ram ProMaster have recalls?

NHTSA lists 8 safety recall campaigns for the 2021 Ram ProMaster. The most recent: Equipment adaptive/mobility: wheelchair restraints/securement (December 2025), Engine and engine cooling: cooling system (October 2025), and Back over prevention: sensing system (August 2025). 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 2021 Ram ProMaster?

Owners have filed 111 complaints about the 2021 Ram ProMaster with NHTSA. The components named most often are back over prevention (24), unknown or other (21), and electrical system (19). 1 complaint involved a crash and 3 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.
