Does F-250 take regular gas?

The F-250’s fueling needs depend on the engine installed. In short, gasoline-powered F-250s can use regular gasoline (87 octane), while the diesel variant runs on diesel fuel only. This article breaks down the options and what to use for peak performance and reliability.


Fuel options by engine


The F-250 is offered with both gasoline and diesel powertrains. Knowing which engine your truck has will determine whether regular gasoline or diesel is required.



  • Gasoline engines: The F-250 offers gasoline V8 options, including a 6.2-liter and a 7.3-liter V8. These engines are designed to run on regular unleaded gasoline with an octane rating of 87 (AKI). Premium gasoline is not required for normal operation.

  • Diesel engine: The F-250 also offers a 6.7-liter Power Stroke diesel. This engine uses diesel fuel only and is not compatible with gasoline.


In brief, if your F-250 is equipped with gasoline engines, you can and should use regular 87-octane gasoline. If you have the diesel variant, use diesel fuel exclusively. Always check your specific model year’s owner’s manual for any year-to-year nuances.


Octane recommendations for gasoline-fueled F-250s


Understanding octane can help prevent engine knock and ensure smooth towing performance. The following guidelines apply to most current gasoline F-250 configurations.



  • Regular grade (87 octane) is sufficient for daily driving and common towing scenarios.

  • Higher-octane fuels (89–93 octane) are optional and not required for normal operation, though some drivers may choose them for marginal performance or peace of mind under heavy loads or extreme heat. Always follow the octane guidance in your owner’s manual for your exact model/year.


Bottom line: for typical use, regular 87-octane gasoline is acceptable and recommended for gasoline-powered F-250s. If you notice knocking or pinging under heavy load, consult your manual or a Ford service professional before switching fuels.


Diesel fuel considerations (Power Stroke)


Fuel type and guidelines


The diesel variant (6.7-liter Power Stroke) requires diesel fuel only. Do not use gasoline in this engine. Some model years and regional specifications may note compatibility with higher biodiesel blends; always verify the biodiesel allowance and the recommended fuel type in your manual or with a Ford service advisor.


For everyday diesel fueling, use standard diesel (No. 2D) as prescribed, and consult the manual if you’re considering biodiesel blends (such as B20) or any regional fueling considerations. Fueling practices can impact long-term reliability and warranty coverage, so adhere to Ford’s guidance for your exact truck year and configuration.


Summary


In summary, the Ford F-250’s fuel choice hinges on the engine installed. Gasoline F-250s run on regular unleaded gasoline (87 octane) with premium not required; the diesel-equipped F-250 uses diesel fuel only. Always confirm fuel requirements in the owner’s manual for your specific model year and engine to ensure optimal performance and warranty adherence.


Summary of key points


- Gasoline engines (6.2L and 7.3L) answer to regular 87-octane gasoline

- Diesel engine (6.7L Power Stroke) runs on diesel only

- Premium gasoline is optional for gasoline engines and not required for normal use
