How do I know if my Ford is gas or diesel?
The quickest way to know is to check the badge and the fuel door: diesel models carry Power Stroke (and sometimes EcoBlue in Europe) branding, while gasoline engines bear EcoBoost, V8, or other gasoline-related badges. For certainty, consult the window sticker or decode the VIN.
If you’re unsure after a first glance, use these steps to verify the fuel type in your specific Ford model. The guidance covers common exterior cues, official records, and model-family specifics to help you determine whether your vehicle runs on gas or diesel.
Visual cues and official labels
These quick checks rely on what you’ll typically see on the outside or inside the vehicle. They are usually the fastest way to identify fuel type without digging into manuals or records.
- Badge or nameplate on the tailgate, doors, or engine cover. Diesel models typically show Power Stroke (and in some markets EcoBlue), while gasoline models show EcoBoost, V8, or other gasoline-related designations.
- Fuel filler door label. Many Ford vehicles mark the fuel type near the filler cap (Diesel or Gasoline); the nozzle color can also be a clue (diesel nozzle is often red).
- Window sticker or Monroney label (for new cars). This documents the engine type and the corresponding fuel requirement.
- Owner’s manual or in-vehicle information system (IVIS/MyFord app). These sources list the exact engine and fuel specification for your VIN.
- Engine bay markings. Some diesel engines display a Power Stroke badge or specific engine codes on the valve covers or engine cover.
These cues are usually reliable, but for absolute certainty you should confirm via an official record or a VIN lookup.
Official records and VIN verification
When badges aren’t conclusive (for example, on older models or certain markets), turn to official documentation and VIN-based checks to confirm the fuel type.
- VIN (Vehicle Identification Number) lookup. The engine code can often be retrieved from the VIN and matched to a Ford spec sheet to reveal whether the engine is diesel or gasoline.
- Ford dealer or official service portal. A quick VIN input will yield the exact engine and fuel type, along with available options for your year and trim.
- Original window sticker or purchase documents. These show the exact engine and the required fuel, useful for used vehicles still in possession of those records.
Using a VIN decode or a dealer lookup provides a definitive answer, especially for used vehicles where badges may have faded or been replaced.
Model-family notes: what to expect by Ford line
Trucks and commercial models
Ford’s heavy-duty and popular pickup line often features diesel options alongside gasoline engines. The presence of a Power Stroke badge typically indicates a diesel engine, while EcoBoost or conventional V8 badges indicate gasoline. In recent years, some F-150 trims have offered a diesel option (notably the 3.0L Power Stroke in certain model years), while most earlier or standard editions run on gasoline.
- F-Series Super Duty (e.g., F-250/F-350) trucks commonly offer diesel Power Stroke options, with gasoline engines available in other trims. Diesel models will typically bear the Power Stroke branding.
- F-150, the lighter-duty pickup, is primarily offered with gasoline engines; a diesel option exists in some model years with a Power Stroke badge, or may be absent entirely depending on year and market.
For commercial or specialty trucks, badge language and engine options vary by year and region. If you rely on a specific model, checking the badge, filler label, or VIN remains the most reliable method.
Vans and SUVs
Ford’s van and SUV options span gasoline and diesel, with diesel branding appearing on models that use Power Stroke in regions that offer it. European-market vans sometimes use EcoBlue diesel, while U.S. market versions typically follow the Power Stroke/garage-badge approach for diesel options and EcoBoost or other gasoline badges for gas engines.
- Transit (and related commercial vans) may show EcoBlue diesel in markets outside the U.S.; in the U.S., current configurations more often use gasoline EcoBoost or other gasoline engines, with diesel variants identified by Power Stroke branding where available.
- Passenger SUVs and crossovers from Ford generally rely on gasoline engines, with diesel options less common in recent U.S. models.
Because regional offerings vary, always confirm with the badge, the filler label, or an official VIN/Windows sticker, especially if you’ve moved between markets or are looking at a used vehicle.
Bottom line and quick tips
To determine whether your Ford is gas or diesel, start with visible clues (badges and filler label), then verify with official records (window sticker, VIN, or dealer). For used vehicles, the VIN decode is often the most reliable method to confirm the exact engine and fuel type.
Summary: Check the exterior branding and the fuel door label first, then consult the VIN or window sticker for a definitive answer. When in doubt, contact a Ford dealer with your VIN for a precise confirmation.
Does Ford use gas or diesel?
The lineup of Ford engine options includes something for everyone: an affordable gas engine, a fun and efficient EcoBoost engine, silent electric driving, hybrids that blend traditional benefits and future-looking efficiency, and a diesel that can tow just about anything.
How to tell if a vehicle is gas or diesel?
You can tell if a vehicle is gas or diesel by checking the fuel cap or the fuel door for a label, which will clearly state "Diesel" or "Gasoline". Other indicators include the shape of the fuel filler neck, an engine inspection for spark plugs, or looking for specific stickers on the car's exterior or instrument panel.
How to check

- Check the fuel cap or door: Open the fuel door and look for a label on the inside of the door or on the fuel cap itself. It will state "Diesel Only" or "Unleaded Gasoline Only".
- Look for stickers: Rental vehicles or newer cars may have stickers near the fuel filler neck or on the car's dashboard or key fob indicating the required fuel type.
- Inspect the engine: If you have access to the engine, a gasoline engine will have spark plug wires connected to spark plugs, while a diesel engine will not.
- Note the fuel filler neck size: The opening for a diesel car is typically larger than for a gasoline car, so a diesel pump nozzle will not fit into a gasoline car's filler neck, and a gasoline nozzle will be too small for a diesel car.
- Consult the owner's manual: The most reliable method is to check the vehicle's owner's manual, which will specify the correct fuel type.
How to identify car fuel type?
Check the sticker on the inside of the fuel door or the owner's manual for the correct fuel type and octane rating for your car. You can also find this information on the dashboard near the fuel gauge or by looking at the fuel cap.
Where to find your fuel information
- Inside the fuel door: Look for a sticker that specifies "Unleaded Fuel Only" or "Diesel Fuel Only" and the required octane rating, like 87 for regular or 91-94 for premium.
- Owner's manual: The manual contains detailed information about the recommended fuel type, octane rating, and even what to do if you use the wrong fuel.
- Near the fuel gauge: Some cars display the recommended fuel type on a sticker on the dashboard, near the fuel gauge.
- Gas cap: The gas cap itself may have a sticker or a symbol indicating the correct fuel type.
Why using the correct fuel is important
- Avoid engine damage: Using a fuel with a lower octane rating than your car requires can cause knocking, poor performance, and potential long-term engine damage.
- Warranty protection: Using the wrong fuel can also void your warranty.
