24 MPG combined is a respectable figure for the 2018 Ford F150 2WD with the base payload package, light truck tires, and the 3.0L 6-cylinder diesel engine. This isn’t your contractor’s F150, nor is it the EcoBoost-powered daily driver for suburban families. This truck is specifically for buyers who need light-duty hauling or towing capability with an emphasis on fuel efficiency. Think small business owners making local deliveries, or weekend warriors hauling smaller boats or campers. For them, the diesel’s efficiency sweet spot offsets its higher initial cost.

City and highway performance

The EPA estimates the 2018 F150 equipped this way at 22 MPG in the city and 28 MPG on the highway. These figures reflect this engine’s design. The 3.0L diesel thrives at lower RPMs, making it relatively efficient in stop-and-go city driving compared to larger gasoline engines. The 28 MPG highway figure shows the engine’s potential on longer trips where consistent speeds prevail. The 10-speed automatic transmission (S10 designation) plays an important role here, keeping the engine in its optimal power band for efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for this specific 2018 Ford F150 configuration at $2,300. This calculation is based on driving 15,000 miles per year, using the EPA’s combined MPG figure, and assuming the national average fuel price for diesel. Keep in mind that your actual fuel costs will vary depending on your driving habits, the type of driving you do, and current diesel fuel prices in your area. If you primarily drive on the highway or consistently achieve better than the EPA estimate, your annual fuel costs could be lower. However, aggressive driving or frequent towing will certainly increase them. If you’re considering other F150 MPG configurations, be sure to investigate all Ford fuel economy data.

Real-world expectations

While the EPA figures provide a useful benchmark, real-world fuel economy often differs. Owners of this particular F150 configuration frequently report figures close to the EPA estimates, but payload and driving style have a dramatic impact. Hauling heavy loads, even within the vehicle’s payload capacity, can significantly reduce MPG. Aggressive acceleration and high speeds will also negatively affect fuel economy. Keeping your speed below 70mph on the highway is a proven way to see results closer to the EPA rating.

How it compares

The 2018 F150 2WD 3.0L diesel’s fuel economy is a key selling point compared to many competitors. A similarly equipped 2018 Chevrolet Silverado 1500 with the 5.3L V8 generally achieves around 19 MPG combined. A Ram 1500 with the EcoDiesel V6 hovers around 22 MPG combined for the same model year. This two to five MPG difference can be an important factor for buyers who prioritize fuel efficiency and drive long distances. This F150 has better fuel economy for the model year. It’s worth noting that the newer F150 PowerBoost hybrid delivers a slightly higher rating in some configurations, depending on the model year. Review the F150 MPG across all years to make the most informed decision. For buyers focused on maximizing MPG without sacrificing truck capability, this diesel F150 remains a great choice, trading raw power for measured efficiency.

Tips to maximize efficiency

Regular maintenance is critical for optimal fuel economy. Ensure your tires are properly inflated to the pressure listed on the door jamb. Low tire pressure increases rolling resistance and reduces MPG. Keep up with scheduled oil changes and air filter replacements. A clean air filter allows the engine to breathe easier, improving combustion efficiency.

Driving habits play a major role in fuel consumption. Avoid aggressive acceleration and hard braking. Anticipate traffic flow and maintain a steady speed whenever possible. Using cruise control on the highway can help minimize fluctuations in speed and improve fuel efficiency.

Reduce unnecessary weight in the truck bed. Extra weight increases the engine’s workload and reduces fuel economy. Remove any items you don’t need, such as tools or equipment. Even small amounts of weight can add up and negatively affect MPG over time.

Consider using the Tow/Haul mode only when towing or hauling heavy loads. In normal driving conditions, this mode can reduce fuel economy by altering shift points. The standard driving mode is optimized for efficiency and provides the best MPG for everyday use. When operating a diesel engine, it is important to allow it to warm up at idle for a few minutes, especially in cold weather. This helps ensure that the engine is lubricated properly and operating at its optimal temperature for peak efficiency.
