Read for lake-effect country
What counts on a 2020 Jeep Gladiator from Michigan to Tennessee
None of the factory data on this page changes from one region to the next, but what deserves a second look does. Below are the 2020 Jeep Gladiator lines that matter for a Bowling Green winter, a spring of broken pavement, a boat on the hitch or a long descent in the hills.
Tire choices for squall and thaw
Big wheels look good, but after a March commute on Detroit or Cleveland streets they are the ones that come home bent. This year's sizes run from 245/75R17 on 17-inch wheels to 255/70R18 on 18-inch wheels; the smaller fitment carries a taller sidewall that absorbs pothole strikes and usually costs less to replace.
The oil grade on a January morning
The 2020 Jeep Gladiator fluids table lists SAE 0W-20, with 5 qt 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.
Traction for snowbelt hills and hollows
This model year offers four-wheel drive. In Kentucky, the payoff comes in the first hour of a storm, before plows reach side streets, and on boat ramps slick with algae where a two-wheel-drive tow vehicle can spin. Keep the system's limits in mind on ice: driven wheels add grip for going, not for stopping or turning.
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.
Pressure, potholes and the thermometer
Whatever size the Gladiator wears, from the factory 245/75R17 on up, correct inflation is the cheapest pothole defense there is: a soft tire lets the wheel slam into the far edge of the hole. Check pressures when the tires are cold, since a reading taken after a highway run will look high.
Antifreeze for both ends of the year
The system holds 11.2 qt of OAT coolant (10-year/150,000-mile formula). Stellantis manuals call for a 50/50 mix, good to about -34°F (-37°C), which is colder than a typical Great Lakes winter night; the real risk is dilution from top-ups with plain water. The same mix raises the boiling point for a loaded summer climb through the Tennessee mountains. A cheap tester checks the strength each fall.
Tank size for hill country
The 2020 Jeep Gladiator holds 22 gallons of fuel. Once you leave the interstate in West Virginia or eastern Kentucky, mountain routes can run a long way between stations, and the climbs burn more fuel than flat miles do. Fill up before heading into the hills.
Capacities, ratings and service intervals: Stellantis data for the 2020 Gladiator. The Great Lakes reading of them is independent and is not factory or dealer advice.
2020 Jeep Gladiator questions
How much oil does the 2020 Jeep Gladiator take?
With a filter change: 3.6L engine, 5 qt / 4.73 L. Capacities are from the owner's manual; check the dipstick or oil-life display after filling.
What kind of oil does the 2020 Jeep Gladiator use?
3.6L engine: API Certified SAE 0W-20 (MS-6395) and Engine oil filter: Mopar filter or equivalent.
When is the first scheduled maintenance on the 2020 Jeep Gladiator?
At 20,000 miles or 2 years: inspect the cv/universal joints; inspect front suspension, rear suspension, tie rod ends, 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; replace air conditioning/cabin air filter. Oil changes in between follow the oil-change indicator.
Where can I find the 2020 Jeep Gladiator 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 2020 Jeep Gladiator get?
The EPA rates the 2020 Jeep Gladiator at 19 MPG combined, depending on the version. 3.6L 6-cylinder, 6-speed manual, 4WD: 16 city / 23 highway / 19 combined; 3.6L 6-cylinder, 8-speed automatic, 4WD: 17 city / 22 highway / 19 combined. Ratings are the EPA's laboratory figures from fueleconomy.gov; real-world mileage varies with driving, load and weather.
What size tires does the 2020 Jeep Gladiator use?
Factory tire sizes: 245/75R17 (Sport, Sport S); 255/70R18 (Overland); LT285/70R17C (Mojave, Rubicon). The recommended cold inflation pressure for your exact tires is on the tire placard on the vehicle, not in a single table.
Does the 2020 Jeep Gladiator have recalls?
NHTSA lists 7 safety recall campaigns for the 2020 Jeep Gladiator. The most recent: Electrical system: instrument cluster/panel (September 2024), Power train: clutch assembly (February 2023), and Power train: clutch assembly (January 2021). 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.
