What You'll Learn
How to check your car's fuel type
It is essential to check and verify your car's fuel type to ensure legal compliance, understand its environmental impact, and maintain its performance and longevity. Here are some ways to determine the correct fuel type for your car:
Check the Owner's Manual
The vehicle's owner's manual typically specifies the recommended fuel type. It will indicate whether your car requires regular, midgrade, or premium fuel and the octane level specified (e.g., 91 or 93 octane). If your car says "premium fuel required" and the owner's manual specifies a higher octane level, it is best to use the recommended premium fuel to avoid potential engine damage and performance issues.
Look for Labels Near the Fuel Cap or Fuel Gauge
The fuel type information may also be listed near the gas cap or the fuel gauge. Diesel vehicles, for example, often have a label that says "diesel fuel only." Additionally, some flex-fuel vehicles that can run on E85 (a blend of 85% ethanol and 15% gasoline) may have a bright yellow fuel cap as an indicator.
Online Fuel Type Check Services
You can use online services, such as CarCheckup in the UK, that provide accurate fuel type information for your vehicle. By entering your vehicle's registration number, you can receive a detailed report on the fuel type, ensuring that you have the correct documentation and helping you make informed decisions regarding insurance and environmental impact.
Consider the Engine Design and Octane Fuel Requirements
Understanding your engine's design and its octane fuel requirements can also help determine the correct fuel type. Higher-octane fuel is often used in high-compression engines to prevent premature ignition of the fuel-air mixture. If you are driving at higher altitudes, consider that lower-octane fuel is typically sold at these elevations and is suitable for older vehicles. However, if your car uses high-octane fuel, you may need to fuel up at a lower altitude.
Remember, choosing the right fuel for your car is crucial. Using the wrong type of fuel can lead to severe engine damage and costly repairs. By following these steps, you can ensure that you are using the appropriate fuel for your vehicle.

The environmental impact of different fuels
Fossil fuels emit harmful air pollutants, including benzene, formaldehyde, and particulate matter, which have been linked to serious health issues such as asthma, cancer, heart disease, and even premature death. In 2018, fossil fuel-related pollution was attributed to approximately 350,000 premature deaths in the United States alone, with communities of color and low-income communities being disproportionately affected. Additionally, the extraction, transportation, and refining of fossil fuels contribute to environmental damage and climate change.
The burning of fossil fuels releases greenhouse gases, particularly carbon dioxide, which trap heat in the Earth's atmosphere, contributing to global warming and climate change. Ocean acidification is another consequence, as the oceans absorb a significant portion of the emitted carbon dioxide, altering their chemistry. Fossil fuel extraction methods, such as underground and surface mining, fracking, and drilling, also pose risks to both the environment and human health. Underground mining, for example, is dangerous for miners due to the risk of mine collapses and exposure to toxic gases and coal dust. Surface mining, or strip mining, while safer for miners, causes extensive damage to wildlife habitats and increases carbon emissions.
Fracking, another extraction method, involves injecting water mixed with chemicals and sand into wells, creating environmental and health issues such as air and water pollution. It also produces large amounts of contaminated wastewater, which can contaminate groundwater supplies if not properly disposed of. Drilling for fossil fuels can also be dangerous, as it involves digging deep into the Earth's surface and can result in gas leaks, with natural gas being primarily composed of methane, a potent greenhouse gas.
Transitioning to clean energy sources and implementing policies to phase out fossil fuel subsidies are crucial steps towards mitigating the environmental and health impacts of fossil fuels. Embracing alternatives such as electricity for vehicles can help reduce carbon emissions and improve air quality, contributing to a more sustainable future.

How fuel type affects insurance and resale value
The type of fuel your car uses can significantly impact its resale value and insurance premiums. With growing awareness of environmental impacts and the necessity to reduce emissions, fuel-efficient cars are in demand. Electric vehicles (EVs) and hybrids are gaining popularity due to their lower carbon dioxide emissions and reduced greenhouse gases. As a result, petrol and diesel vehicles, which have higher emissions, may experience faster depreciation and lower resale values. However, diesel cars tend to have higher resale values compared to petrol cars due to their lower depreciation rates and better fuel efficiency for long journeys.
Local regulations, such as low-emission zones, and changing market preferences for environmentally friendly transportation, further contribute to the resale value of different fuel types. For example, concerns over carbon emissions and potential future restrictions have negatively impacted the resale value of diesel cars, despite their traditionally higher fuel efficiency. On the other hand, eco-friendly electric and hybrid vehicles may retain their value better, especially if they have advanced technology and are within their warranty period.
When it comes to insurance premiums, fuel type can be a factor in calculating these costs. Insurance providers consider various aspects, including the vehicle's value, age, location, driver's profile, and average distance travelled. Diesel-powered cars are generally priced higher and may result in slightly higher insurance premiums due to their impact on the vehicle's value. Additionally, diesel vehicles may be subject to higher repair costs, as they are considered more powerful and may require specialised parts.
On the other hand, electric vehicles with advanced technology may be less desirable to thieves and may have lower insurance premiums due to their reduced theft risk. Hybrid and electric cars often have enhanced safety features, which can further reduce insurance costs. Ultimately, while fuel type can impact insurance premiums and resale value, it is just one of many factors that influence these costs, and other considerations, such as the vehicle's make, model, age, and maintenance, also play a significant role.

How to identify if your car uses diesel or gas
If you're unsure about what type of fuel your car takes, there are several ways to identify whether it uses diesel or gas. Firstly, check the inside of the fuel door for a label. This will usually indicate whether the car takes 'Diesel Fuel Only' or 'Gasoline Only'. If there's no label, you can check the fuel filler neck, the car key, or the instrument bundle near the fuel gauge. Some cars also have stickers on the fuel filler neck or instrument bundle, which indicate the type of fuel used. Car rental companies, in particular, are known to place stickers on their cars to show which fuel is required.
Another way to identify the type of fuel your car uses is by checking the model name. Many diesel cars have a 'D', 'TDI', 'HDi', 'GTD', 'dCi', or 'JTD' in their model name. For example, a BMW 745d or a Lexus IS 220d has a 'D' in the model name, indicating a diesel engine. However, this isn't always the case, and some cars with a 'D' in the model name may not be diesel, so it's best to look for other clues as well.
You can also identify the type of fuel your car uses by looking at the rev meter. In most cases, the red area begins at around 6000 on petrol cars, and 4500-5000 on diesel cars. Additionally, diesel cars often have a glowplug (a heating device) indicator that lights up when you turn the key to the 'on' position without igniting the engine.
If you're still unsure, you can try checking the size of the fuel pump nozzle. Diesel nozzles are usually thicker than those for gasoline. If you're struggling to insert a diesel nozzle, it's likely your car requires gasoline. However, be careful, as it's much easier to insert a gasoline nozzle into a diesel car, which can cause damage to components such as the fuel pump.
Finally, you can rely on your senses. Modern diesel engines are quieter, but many still produce a distinctive sound and stronger vibrations than gasoline engines. Diesel cars also tend to emit darker and thicker smoke, especially during acceleration.
