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 3500.

2015 Ram 3500 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 (driver's side B-pillar or rear edge of the driver's door), which lists the pressures for your exact tire size and load.
Spare
The manual covers a compact spare, a full-size spare, a limited-use spare or a tire service kit in place of a spare, depending on equipment.
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 (2015 Ram 2500 Heavy Duty Specifications, 2015 Ram 3500 Heavy Duty Specifications). Pressure and spare notes from the owner's manual.

2015 Ram 3500 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.

Additional Inspections

  • Inspect front suspension, tie rod ends, and replace if necessary
  • 2500/3500 Models: 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

Flush and replace the engine coolant at 10 years or 150,000 miles (240,000 km) whichever comes first
Change automatic transmission fluid and filter(s) (six-speed automatic only), if using your vehicle for police, taxi, fleet, or frequent trailer towing
Change automatic transmission fluid and filter(s) (six-speed automatic only)
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

Oil change indicator (2500-3500 models)

  • Oil change intervals must not exceed 8,000 miles (13,000 km), twelve months or 350 hours of engine run time, whichever comes first
  • Severe operating conditions can bring on the change oil message as early as 3,500 miles (5,600 km)
  • ** The spark plug change interval is mileage based only, yearly intervals do not apply

Severe duty (all models)

  • Change engine oil at 4,000 miles (6,500 km) if the vehicle is operated in a dusty and off-road environment or predominantly at idle or very low engine RPM

Once a month or before a long trip

  • Check engine oil level
  • Check windshield washer fluid level
  • Check tire pressure and look for unusual wear or damage. Rotate tires at the first sign of irregular wear, even if it occurs before the oil indicator system turns on
  • Check the fluid levels of the coolant reservoir, brake master cylinder, power steering (2500/3500 Models Only) and automatic transmission (six-speed only) and fill as needed
  • Check function of all interior and exterior lights

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 automatic transmission fluid if equipped with dipstick
  • Inspect brake pads, shoes, rotors, drums, hoses and park brake
  • Inspect engine cooling system protection and hoses
  • Inspect exhaust system
  • Inspect engine air cleaner if using in dusty or off-road conditions
  • Lube the front drive shaft fitting (2500/3500 (4x4) models only)

2015 Ram 3500 owner's manuals & publications

The manufacturer's owner's manual, quick guides, radio manuals, supplements and warranty booklets for the 2015 model year.

Great Lakes owner notes

What counts on a 2015 Ram 3500 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 2015 3500 figures above and flag the ones that carry the most weight in Tennessee.

What the manual says about oil

The 2015 Ram 3500 fluids table lists SAE 5W-20 or 5W-30 by temperature (5.7L), SAE 0W-40 (6.4L) and SAE 15W-40 or 5W-40 by temperature (6.7L Cummins turbo diesel), with 7 qt (5.7L), 7 qt (6.4L) and 12 qt (6.7L Cummins turbo diesel) per change. Lake-effect winters are full of short, cold trips: to work, to school, to the store and home again before the engine reaches temperature. That pattern is tough on oil, so let the oil-change indicator set the interval and never stretch it.

Starting in single digits

Battery care in this schedule: inspect it and clean and tighten the terminals as required at each oil change, and the spec sheet rates it at 730 cold-cranking amps. A battery that bakes through a Nashville or Memphis summer ages faster, then gets found out by the first hard freeze. Have it load-tested in fall rather than waiting for a slow crank.

Drive systems for lake-effect snow

The 2015 lineup includes four-wheel drive. Power at both axles pays off when a band off Lake Erie buries the Snowbelt east of Cleveland, or on a steep, unplowed road out of a hollow in eastern Kentucky. It gets you moving; stopping on ice is still up to the tires.

Cold mornings and the tire-pressure light

Air pressure falls about 1 psi with each 10°F drop, so the swing from a gray, mild lake-effect afternoon to a clear, frigid morning can trip the warning light overnight. Set pressures cold, to the door-jamb placard. An underinflated tire is also easier to damage in a pothole, because the rim sits closer to the edge it hits. The schedule asks you to check pressures and look for unusual wear or damage.

Boats, campers and Appalachian grades

The schedule lists axle fluid, automatic transmission fluid and transfer case fluid service for frequent trailer towing, starting at 20,000 miles. Whether it is a fishing boat headed for the Ohio River or a pop-up camper bound for the Smokies, the extra heat of towing ages these fluids faster, most of all on long July climbs.

Winter fuel and DEF

The diesel's biodiesel limit is up to B5; up to B20 on pickups and Chassis Cabs with the B20 option. Diesel exhaust fluid freezes at about 12°F, and the truck's DEF system is built with heaters to thaw it after a cold start; never add anything to the fluid to stop it freezing. Tank capacity: 5.5 gal. Keep spare jugs somewhere that doesn't swing between hard freezes and summer heat.

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.

2015 Ram 3500 questions

How much oil does the 2015 Ram 3500 take?

With a filter change: 5.7L engines (SAE 5W-20, API certified), 7 qt / 6.6 L; 5.7L engine (SAE 5W-30, API certified), 2500/3500 trucks operating above 14,000 lb (6,350 kg) gross combined weight rating, 7 qt / 6.6 L; 6.4L engines (SAE 0W-40 meeting MS-12633, all operating temperatures), 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 2015 Ram 3500 use?

5.7L engine: SAE 5W-20, API certified (MS-6395); 5.7L engine, 2500/3500 trucks operating above 14,000 lb (6,350 kg) gross combined weight rating: SAE 5W-30, API certified (MS-6395); 6.4L engine: SAE 0W-40 full synthetic, API SN, for all operating temperatures (MS-12633); Engine oil filter: Mopar brand engine oil filter; 6.7L Cummins turbo diesel, ambient above 0°F (-18°C): SAE 15W-40, API CJ-4 required; Cummins CES 20081 products also acceptable (MS-10902); 6.7L Cummins turbo diesel, ambient below 0°F (-18°C): SAE 5W-40 synthetic, API CJ-4 required (MS-10902); and 6.7L Cummins turbo diesel: Mopar brand engine oil filter.

When is the first scheduled maintenance on the 2015 Ram 3500?

At 20,000 miles or 2 years: inspect front suspension, tie rod ends, and replace if necessary; 2500/3500 models: 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. Oil changes in between follow the oil-change indicator.

Where can I find the 2015 Ram 3500 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 2015 Ram 3500 get?

The EPA doesn't publish a fuel-economy rating for the 3500: 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 2015 Ram 3500 have recalls?

NHTSA lists 16 safety recall campaigns for the 2015 Ram 3500. The most recent: Air bags: side/window (August 2021), Wheels: lugs/nuts/bolts/studs (May 2021), and Latches/locks/linkages: tailgate (May 2019). 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 2015 Ram 3500?

Owners have filed 137 complaints about the 2015 Ram 3500 with NHTSA. The components named most often are power train (32), engine (28), and service brakes (24). 3 complaints involved a crash and 5 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.

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.
