When you’re driving a truck, it’s important to know what kind of fuel it requires. Most trucks either run on gasoline or diesel fuel, and putting the wrong type of fuel in your truck can lead to serious problems. In this article, we’ll go over some simple ways to tell if your truck runs on gas or diesel.
Check the Fuel Cap
One of the easiest ways to tell if your truck runs on gas or diesel is to check the fuel cap. Gasoline and diesel fuel caps are usually labeled with the type of fuel that the truck requires. If the cap says “Gasoline Only,” then your truck runs on gas. If it says “Diesel Fuel Only,” then your truck runs on diesel.
Look at the Fuel Gauge
Another way to tell if your truck runs on gas or diesel is to look at the fuel gauge. Gasoline and diesel fuel have different densities, so the fuel gauges for these two types of fuel are calibrated differently. If the gauge is labeled with “E” (for empty) at the top and “F” (for full) at the bottom, then your truck runs on gas. If the gauge is labeled with “D” (for diesel) at the top and “F” (for full) at the bottom, then your truck runs on diesel.
Listen to the Engine
If you’re still not sure what type of fuel your truck runs on, you can try listening to the engine. Gasoline and diesel engines sound different, so if you know what to listen for, you can tell which type of fuel your truck requires. Gasoline engines tend to be smoother and quieter, while diesel engines are louder and produce more vibrations.
Check the Manual
If you have access to the owner’s manual for your truck, you can check there to see what type of fuel it requires. The manual should have a section that explains what kind of fuel your truck needs, as well as any other important information about fueling your vehicle.
Ask a Mechanic
If you’re still not sure what type of fuel your truck requires, you can always ask a mechanic. A professional mechanic will be able to tell you what kind of fuel your truck needs and can answer any other questions you may have about fueling your vehicle.

A: Putting diesel fuel in a gas truck can cause serious damage to the engine and other components of the vehicle. It can also be dangerous and should be avoided at all costs.
Q: Can you put gas in a diesel truck?
A: No, you should never put gasoline in a diesel truck. Doing so can cause serious damage to the engine and other components of the vehicle.
Q: How do I know if my truck is flex fuel?
A: Flex fuel vehicles are designed to run on a blend of gasoline and ethanol, which is usually labeled as E85. If your truck is flex fuel, it should have a yellow gas cap and a sticker on the fuel door that says “E85/Gasoline.”
