What is the gas mileage on a 1994 Ford f350?
Gasoline-powered 1994 Ford F-350s typically averaged about 9–14 miles per gallon (mpg) in mixed driving, with the smaller 5.8-liter V8 usually nearer the upper end and the larger 7.5-liter V8 nearer the lower end. Four-wheel-drive versions generally logged a few mpg less than two-wheel-drive models.
In this article, we break down how mpg could vary by engine and setup, and highlight factors that influence real-world fuel economy on a 1994 F-350. The figures reflect typical owner reports and period testing, not a single official rating.
Engine options and mileage
Gasoline engines
Two common gasoline powertrains shaped fuel economy for the 1994 F-350. Each combination of engine, drivetrain, and transmission affects mpg in meaningful ways.
- 5.8L V8 (351W) — roughly 11–14 mpg combined; about 13–15 mpg on the highway; 9–12 mpg in city driving. 2WD configurations tend to be more efficient than 4WD.
- 7.5L V8 (460) — generally 9–12 mpg combined; highway around 11–14 mpg; city roughly 7–10 mpg. Heavier payloads or towing can push these numbers lower.
Real-world mileage for gasoline F-350s varies with payload, towing, terrain, and maintenance. The ranges above reflect typical experiences from the era.
Diesel option (for context)
For comparison, the 1994 F-350 also offered a turbocharged diesel option (7.3L Power Stroke on many Heavy Duty models). Diesel variants usually deliver higher highway efficiency, particularly when not towing, but the exact numbers depend on configuration and usage.
- 7.3L Power Stroke (diesel) — commonly about 14–18 mpg combined; highway often in the 17–21 mpg range, with city mpg lower due to stop-and-go use. Real-world results vary with payload and driving style.
Diesel engines typically offer better highway efficiency than gasoline counterparts of the same era, but payload, towing, and driving conditions have a large impact on actual mileage.
Factors that influence mileage in practice
Beyond engine choice, several practical factors can swing fuel economy on a 1994 F-350:
- Drivetrain: 4WD versions generally consume more fuel than 2WD models.
- Payload and towing: Heavier loads dramatically reduce mpg.
- Maintenance and tune: Worn spark plugs, dirty air filters, and poor fuel-system condition can lower efficiency.
- Terrain and driving style: Urban stop-and-go drains mpg; steady, highway cruising improves it.
- Tire size and inflation: Underinflated or oversized tires raise rolling resistance and reduce fuel economy.
Keeping the engine and drivetrain in good condition, maintaining proper tire pressure, and moderating payload can help maximize mileage within the truck’s inherent limits.
Summary
In short, a 1994 Ford F-350’s gas mileage depends heavily on engine choice and configuration. Gasoline models typically fall in the 9–14 mpg combined range, with the 5.8L V8 leaning toward the higher end and the 7.5L V8 toward the lower end. Diesel variants (where equipped) usually offer better highway efficiency, but real-world numbers vary with payload, towing, and driving conditions.
