What Is the Mileage of a 7.3 Diesel?

When purchasing a vehicle, fuel economy is an important factor to consider. This is especially important for heavy-duty trucks, which may be on the road for a long period of time. While getting an exact mileage per gallon for the 7.3 IDI engine is difficult, we can help narrow the range.

On the highway, an unloaded pickup with this engine should be able to get up to 21 miles per gallon. In the city, expect this to drop to 14 to 15 cents per gallon of fuel.

When hauling or towing heavy loads, your fuel economy will suffer slightly. The more fuel your engine has to burn, the harder it has to work.

Depending on how heavy the load is, this can significantly reduce your fuel economy. According to experts, adding 100 pounds of weight to your truck can reduce your overall fuel economy by up to 2%.

How Long Can A 7.3 IDI Engine Run?

It’s no secret that diesel engines outlast their gasoline counterparts. Because the majority of Ford trucks on the used market are at least 20 years old or older, knowing how long these engines will last may help you make a more informed purchasing decision.

A well-maintained 7.3 IDI can travel up to 500,000 miles. Of course, this will necessitate some effort on your part. The main key to reaching any high mileage milestone for an engine is to adhere to the factory-recommended maintenance schedule.

This process includes regular oil and filter changes. Your owner’s manual will detail a series of checks that should be performed as well as the mileage/time intervals at which they should be performed.

If seemingly minor items are overlooked, they can have a significant impact on the life of your engine, so make sure you understand and follow the maintenance requirements.
