2020 Jeep Wrangler fuel economy (EPA)

The EPA rates the 2020 Jeep Wrangler at 19–25 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).

Source: U.S. EPA and Department of Energy, fueleconomy.gov. MPG is miles per gallon (MPGe for electric operation). Plug-in hybrids list gasoline-only MPG with the electric rating underneath. Annual fuel cost assumes 15,000 miles a year at the EPA's fuel-price assumptions, so yours will differ. Range is total driving range on a full tank or charge.

Cold tire pressure
Not a single number: the owner's manual refers to the tire and loading placard (driver's side door opening), which lists the pressures for your exact tire size and load.
Spare
The sheet lists no spare; the manual describes a matching full-size spare with a pressure sensor, a compact spare, or a tire service kit instead of a spare, depending on equipment.
Lug nut torque
130 ft-lb (176 N·m) (Road wheels), 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 Jeep Wrangler Specifications). Pressure and spare notes from the owner's manual.

2020 Jeep Wrangler 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 the CV/Universal joints
  • Inspect front suspension, tie rod ends, rear suspension, and replace if necessary
  • Inspect the front and rear axle fluid
  • Inspect the brake linings, replace as necessary
  • Adjust parking brake on vehicles equipped with four wheel disc brakes

Additional Maintenance

  • Replace air conditioning/cabin air filter

Replace air conditioning/cabin air filter
Replace Spark Plugs – 2.0L EngineThe spark plug change interval is mileage based only, yearly intervals do not apply
Replace spark plugs – 3.6L EngineThe spark plug change interval is mileage based only, yearly intervals do not apply
Flush and replace the engine, intercooler (if equipped), battery (if equipped), and Motor Generator Unit (MGU) (if equipped) coolant at 10 years or 150,000 miles (240,000 km) whichever comes first
Change the manual transmission fluid if using your vehicle for any of the following: trailer towing, snow plowing, heavy loading, taxi, police, delivery service (commercial service), off-road, desert operation or more than 50% of your driving is at sustained high speeds during hot weather, above 90°F (32°C)
Change transfer case fluid if using your vehicle for any of the following: police, taxi, fleet, or frequent trailer towing
Inspect and replace PCV valve if necessary
Change front and rear axle fluid if using your vehicle for police, taxi, fleet, off-road or frequent trailer towing

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 park brake
  • Inspect engine cooling system protection and hoses
  • Inspect exhaust system
  • Inspect engine air cleaner if using in dusty or off-road conditions
  • Inspect all door latches for presence of grease, reapply if necessary

2020 Jeep Wrangler 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

The 2020 Jeep Wrangler against salt, snow and steep grades

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 2020 Wrangler figures above and flag the ones that carry the most weight in Tennessee.

Pothole season and the factory tire sizes

Smallest factory tire: P245/75R17. 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 Wrangler 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 2020 Jeep Wrangler fluids table lists SAE 5W-30 (2.0L) and SAE 0W-20 (3.6L), with 5 qt (2.0L) and 5 qt (3.6L) 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.

Cranking power for a lake-effect morning

Rated battery output: 650 cold-cranking amps, measured at 0°F. A single-digit night in Traverse City or Fort Wayne cuts what the battery can deliver just as the stiff engine asks more of the starter. Past three winters, an October load test tells you more than the date sticker. Charging comes from a 180-amp alternator.

Which wheels do the pulling

Every 2020 version in the factory data drives with four-wheel drive. That is a real asset on a lake-effect morning in South Bend or Muskegon and on gravel switchbacks in West Virginia, but it does not shorten stopping distances: winter tires and extra following room still decide how a squall ends. On a used Wrangler, check that the system engages and the tires match in size and wear.

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.

Coolant through freeze and climb

Fluids table: OAT coolant (10-year/150,000-mile formula), 10.3 qt (2.0L) and 11.2 qt (3.6L). Scheduled replacement comes at 10 years or 150,000 miles. Stick to that chemistry, since mixing coolant types can shorten their protective life. On a used Wrangler from Tennessee, ask whether the coolant was changed on time, and check the level in the overflow tank with the engine cold before you drive it.

Fuel reserve for storm closures

Fuel capacity: 17.5 to 21.5 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.
