Choosing the right fuel for your car is essential for its smooth operation and can help prevent potential engine problems. The vehicle's owner's manual is the best resource to determine the right fuel for your car. The manual will specify the recommended octane rating and fuel type. If you don't have the owner's manual, you can check the car key, dashboard, fuel gauge, fuel cap, or inside the fuel door for stickers indicating the recommended fuel type and octane rating. Additionally, some car model names can provide hints about the fuel type, with many diesel cars having labels like 'D', 'TDI', or 'HDi'. Using a higher octane fuel than recommended does not enhance your car's performance and is unnecessary unless your car's engine specifically requires it.
How to know what fuel a car uses:
| Characteristics | Values |
|---|---|
| Car model name | Some car model names can hint at the type of fuel a car uses. For example, labels like 'D', 'TDI', 'HDi', etc. indicate diesel. |
| Stickers | Check for stickers on the car key, dashboard, fuel gauge, or inside the fuel cap cover. These usually have straightforward messages indicating the fuel type, e.g., 'Unleaded Gas Only' or 'Diesel Only'. |
| Owner's manual | The vehicle's owner's manual typically specifies the recommended fuel type and octane rating for the car. |
| Online search | If you don't have access to the owner's manual, you can search online for the fuel type recommended for a specific car model, make, and year. |
| Fuel type | Gasoline is available in various octane ratings: 87 (regular), 89 (mid-grade), and 91 or 93 (premium). |
| Fuel efficiency | Using the recommended octane rating can help achieve optimal fuel efficiency. Higher-octane fuel may provide slightly better fuel economy. |
| Engine performance | Using a higher octane fuel than recommended does not improve engine performance unless the engine is specifically designed for it. |
| Engine damage | Using regular gas instead of premium fuel will not damage the engine. |
| Fuel blend | E85 is a blend of 85% ethanol and 15% gasoline, suitable for some flex-fuel vehicles. RON 95/RON 98 are specifications for some European cars. |
| Altitude | Lower-octane fuel is often sold at higher altitudes and is suitable for older vehicles. Modern fuel-injected engines can adjust to lower oxygen content, so continue to use the manufacturer's recommended octane. |

What You'll Learn
Check the car's model name
Checking the car's model name can be a good indicator of the type of fuel the car uses. Many diesel cars have labels like 'D', 'TDI', 'HDi', 'GTD', 'dCi', or 'JTD'. For example, if your car is a Volkswagen Golf TDI, the 'TDI' in the model name indicates that the car has a Turbocharged Direct Injection diesel engine. You can usually find these labels on the back of the car near the trunk. However, it is important to note that the 'D' in the model name may be indicative of another feature, so it is recommended to consider other clues as well.
The car's documentation, such as the owner's manual, can provide valuable information. By checking the section on fluids, you can find details about the type and grade of fuel required for the vehicle. This information is typically clearly indicated in the documentation. Additionally, you can refer to the instrument cluster (digital dash) of the car to look for any written indication of the type of fuel it uses.
While the model name can provide a hint, it is advised not to rely solely on this method to determine the fuel type. It is always a good idea to contact the rental company or refer to the car's documentation for confirmation. They will have all the necessary fuel specifications and can guide you accurately. This information can also be found in the glovebox or driver's side door pocket.
In addition to checking the model name, you can look for stickers placed on the car by rental companies. These stickers are often found on the car key, dashboard, fuel gauge, or inside the fuel cap cover. The messages on these stickers are usually clear and will specify the required fuel type, such as 'Unleaded Gas Only' or 'Diesel Only'.

Look for stickers
One of the easiest ways to determine the type of fuel your car uses is to check for stickers. These are often found on the car key, dashboard, fuel gauge, or inside the fuel cap cover. The messages on these stickers are usually straightforward and may read something like 'Unleaded Gas Only' or 'Diesel Only'. If you cannot find a sticker, the car's documentation in the glovebox or driver's side door pocket may provide information on the fuel type.
Stickers on the car key, dashboard, or fuel gauge can be very helpful in determining the type of fuel your car requires. These stickers usually provide clear instructions on the recommended fuel type. For example, if you see a sticker that says 'Unleaded Gas Only', it indicates that your car requires unleaded gasoline. Similarly, a sticker that reads 'Diesel Only' means that your car runs on diesel fuel. These stickers are often placed in visible locations to make it convenient for drivers to identify the correct fuel type.
The fuel cap cover is another common place to find stickers indicating the recommended fuel type. When you open the fuel cap, look inside the cap or around the fuel door, as there may be a sticker with information about the fuel your car needs. This sticker might specify the fuel type, such as unleaded or diesel, and may also include the octane rating, such as 87 for regular unleaded gasoline. Checking the fuel cap is a quick and easy way to get valuable information about your car's fuel requirements.
In addition to stickers, you can also look for labels near the trunk of the car. Many diesel cars have labels like 'D', 'TDI', 'HDi', or similar variations. For example, a Volkswagen Golf TDI indicates that the car has a Turbocharged Direct Injection diesel engine. While the model name can provide a hint about the fuel type, it is recommended not to rely solely on this information. Combining information from stickers, labels, and the owner's manual will help you confidently determine the correct fuel type for your car.
Overall, checking for stickers is a simple and effective way to identify the fuel requirements of your car. By looking in key locations such as the car key, dashboard, fuel gauge, and fuel cap, you can find valuable information about the recommended fuel type and octane rating. This knowledge will help ensure that you select the appropriate fuel for your vehicle, preventing potential engine problems and maximizing fuel efficiency.
