2021 Jeep Gladiator fuel economy (EPA)

The EPA rates the 2021 Jeep Gladiator at 19–24 MPG combined; the 3.0L 6-cylinder turbo (4WD) is the most efficient and the 3.6L 6-cylinder (4WD) the thirstiest. Every EPA test configuration is below, from the government's fuel-economy database.

City, highway and combined figures are in MPG (MPGe on electricity).

Read for lake-effect country

What counts on a 2021 Jeep Gladiator 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 2021 Gladiator figures above and flag the ones that carry the most weight in Tennessee.

Pothole season and the factory tire sizes

Smallest factory tire: 245/75R17. Freeze-thaw cycles break up asphalt across the Great Lakes states, and one jolt can knock the alignment out without leaving a mark on the wheel. If the steering wheel sits off-center or the Gladiator wanders after a pothole, get the alignment checked before the tire edges wear. A winter set on 17-inch wheels also keeps salt off the originals.

What the manual says about oil

The 2021 Jeep Gladiator fluids table lists SAE 0W-20 (3.6L gasoline) and SAE 5W-40 (3.0L diesel), with 5 qt (3.6L gasoline) and 9 qt (3.0L 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.

Battery checks before the cold

The spec sheet lists 650 to 700 cold-cranking amps. A Gladiator 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

The 2021 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.

Snow plowing is a listed condition

Snow plowing is named in this schedule as one of the uses that calls for earlier fluid service. Keeping a long driveway or a cottage lane open through a west Michigan winter is precisely the kind of work that line describes, so log plowing hours alongside towing.

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.

Winter fuel and DEF

The diesel's biodiesel limit is up to B5; B6-B20 only where state-mandated, use within 30 days. 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: 5.1 gal. Keep spare jugs somewhere that doesn't swing between hard freezes and summer heat.

Fuel reserve for storm closures

Fuel capacity: 18.3 to 22 gallons. Lake-effect whiteouts can shut stretches of I-94 in Michigan or I-90 through the Ohio Snowbelt for hours, so keep the tank from running low between November and March. If you do end up stranded, a running engine for heat needs a tailpipe clear of snow.

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.

2021 Jeep Gladiator questions

How much oil does the 2021 Jeep Gladiator take?

With a filter change: 3.6L gasoline engine, 5 qt / 4.73 L and 3.0L diesel engine, 9 qt / 8.5 L. Capacities are from the owner's manual; check the dipstick or oil-life display after filling.

What kind of oil does the 2021 Jeep Gladiator use?
