To get an accurate mileage estimate, you need to specify the exact year and trim level of the F-250. Then, you can:
* Check the Ford website: Ford's official website usually has fuel economy data for each model year and configuration.
* Consult the EPA's fueleconomy.gov website: This government website provides fuel economy information for most vehicles sold in the US.
* Look at owner reviews: Websites like Edmunds, Kelley Blue Book, and others often have owner reviews that mention real-world fuel economy. Keep in mind that these are subjective and vary based on driving habits and conditions.
Without more specifics, I can only say that the mileage for a Ford Super Duty F-250 diesel generally ranges from 10-18 mpg, but it could be higher or lower depending on the factors listed above.
