2018 Ram 1500 fuel economy (EPA)

The EPA rates the 2018 Ram 1500 at 14–23 MPG combined; the 3.0L 6-cylinder turbo (RWD) is the most efficient and the 5.7L 8-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.

2018 Ram 1500 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 compact spare, non-matching full-size spare or tire service kit, depending on equipment. The compact and non-matching full-size spares have no pressure sensor.
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 (2018 Ram 1500 Specifications). Pressure and spare notes from the owner's manual.

2018 Ram 1500 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.

Great Lakes owner notes

What counts on a 2018 Ram 1500 from Michigan to Tennessee

We read the 2018 1500 owner data, service schedule and spec sheets with Kentucky driving in mind: frozen starts, salted highways, cratered streets and hills. These are the figures worth acting on.

The oil grade on a January morning

The 2018 Ram 1500 fluids table lists SAE 5W-20 or 5W-30 (3.6L) and SAE 5W-20 (5.7L), with 6 qt (3.6L) and 7 qt (5.7L) 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 730 to 800 cold-cranking amps. A 1500 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 2018 lineup includes rear-wheel drive and 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.

Trailer duty in the schedule

Regular towing puts the 2018 Ram 1500 on the schedule's trailer rows: axle fluid, automatic transmission fluid and transfer case fluid service, first at 20,000 miles. A summer of hauling a boat to Lake Cumberland, Norris Lake or a Lake Michigan launch counts. The Great Lakes are fresh water, so a trailer's real corrosion threat here is winter road salt, not the ramp.

Gravel hollow roads and the air filter

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.

Octane from the owner data

The owner data specifies 87 octane, with 89 recommended. A higher grade than the manual asks for adds cost without benefit, while a lower one than required makes the engine pull back ignition timing, which shows most under load on a long Appalachian climb.

Data behind these notes: owner's manual capacities, the Mopar service schedule and factory spec sheets. Regional advice is general, written for drivers from Kentucky to Ohio.

2018 Ram 1500 questions

How much oil does the 2018 Ram 1500 take?

With a filter change: 3.6L engine, 6 qt / 5.6 L and 5.7L engine, 7 qt / 6.6 L. Capacities are from the owner's manual; check the dipstick or oil-life display after filling.

What kind of oil does the 2018 Ram 1500 use?

3.6L engine: SAE 5W-20, API certified (SAE 5W-30 acceptable if 5W-20 is unavailable) (MS-6395); 5.7L engine: SAE 5W-20, API certified (MS-6395); and Engine oil filter: Mopar engine oil filter.

When is the first scheduled maintenance on the 2018 Ram 1500?
