2018 Ford E-350 Super Duty

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 E-350 Super Duty.

Transmission Manual 6-spd

The 2018 Ford E-350 Super Duty continues the E-Series legacy as a robust full-size van and cutaway chassis, pairing a 6.6-quart 5W-30 oil fill with a manual 6-speed transmission and EPA ratings of 14 mpg city, 21 highway, and 16 combined. This model year saw just three owner complaints, focused on the powertrain and service brakes, alongside four recalls, marking it as a relatively quiet entry in the nameplate’s reliability history and a solid, no-surprises workhorse.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 97,500 mi; coolant every 45,000 mi. The big-interval services (every 45,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Every 7,500 mi	Engine Oil (drain & refill) · Engine Oil Filter (replace) · Tire & Wheel Assembly (rotate)
Every 15,000 mi	Accessory Drive Belt (inspect) · Brake Line (inspect) · Brake Linings (inspect) · Brake Rotor (inspect) · Driveshaft (inspect) · Driveshaft U-Joint (inspect)

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2018 Ford E-350 Super Duty dominate in one area — the power train,service brakes, 1 of 3 reports (33%), well ahead of the next concern. None of this vehicle's 4 recall campaigns target the power train,service brakes, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 1 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the power train,service brakes pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
