What changed for the 2027 Ram ProMaster

Nothing we compare (trims, equipment, engines, ratings) changed from 2026 to 2027.

Compared automatically from the manufacturer's trim feature charts, specification sheets, towing guides and the EPA's fuel-economy data for 2026 and 2027. No trim equipment chart is on file for one of the two years, so equipment changes aren't listed. Equipment varies by trim and market; confirm details on a specific vehicle.

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.

2027 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
Manual describes a regular-size spare (which the TPMS does not monitor) and a tire service kit in place of a spare, so it depends on equipment; it also mentions compact temporary spares.
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. Pressure and spare notes from the owner's manual.

2027 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.

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, boot seals, and replace if necessary
  • Inspect the brake pads, replace as necessary

Additional Maintenance

  • Replace the Brake Fluid every two yearsThe brake fluid change interval is time based only, mileage intervals do not apply.

At every oil change

  • Change oil and filter
  • Rotate the tires 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 filter if using in dusty or off-road conditions
  • Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme dusty conditions

Read for lake-effect country

What counts on a 2027 Ram ProMaster from Michigan to Tennessee

Lake-effect squalls, roads soaked in brine, potholes that open with every thaw and long Appalachian grades: driving in the Great Lakes states asks a lot of tires, batteries and undersides. These notes take the 2027 ProMaster figures above and flag the ones that carry the most weight in West Virginia.

Cranking power for a lake-effect morning

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.

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 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.

Electric range in lake-effect cold

Cold weather cuts battery-electric range: the pack is less efficient and cabin heat draws from it as well. Precondition the cabin and battery while still plugged in, lean on the seat heaters, and plan winter trips on I-75 or I-94 with charging stops closer together than the rated range suggests.

Each spec in these notes is pulled from the tables above. The commentary on salt, snow, potholes and grades is general guidance for the Great Lakes states; the owner's manual remains the authority.

2027 Ram ProMaster questions

How much oil does the 2027 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 2027 Ram ProMaster use?

Engine oil: SAE 0W-20 full synthetic or SAE 5W-20, API Starburst certified (MS-6395).

When is the first scheduled maintenance on the 2027 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; 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 2027 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 2027 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.

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.
