What You'll Learn
Check the owner's manual
The owner's manual is the go-to resource for learning about your car's fuel requirements. It will tell you what type of fuel is best for your car and which grade to use. This information is crucial for optimal vehicle performance and longevity.
The manual will also specify the recommended octane rating for your car. Octane ratings represent a fuel's resistance to engine knocking or pinging during combustion. While higher octane fuel is designed for vehicles with high-performance engines, using a higher octane rating than recommended does not enhance your car's performance. It will not make your vehicle faster or more powerful unless your car’s engine is specifically designed to require a higher octane level.
Additionally, the owner's manual can provide guidance on fuel specifications and requirements. This information ensures that you meet regulatory requirements and optimise your vehicle's operation. For example, if you are unsure about what type of gas to put in your car, the owner's manual can help you make the right choice. It is important to familiarise yourself with your car's needs to maintain its performance and efficiency.
If you don't have the owner's manual, you can check the fuel door or the gas cap, as these often have stickers indicating the recommended fuel type and octane rating. This label is typically easy to find and provides valuable information about your car's fuel needs. You can also search online by entering your car's make, model, and year, along with the query "what type of gas to use." This should bring up the relevant information from the owner's manual.

Check the fuel door for a sticker
If you're unsure about your car's fuel type, one of the easiest ways to find out is to check the fuel door for a sticker. This sticker will usually indicate the recommended fuel type and octane rating for your vehicle. It is typically placed inside the fuel door or near the gas cap, making it easily accessible and providing essential information about your car's fuel requirements.
The sticker on your fuel door will guide you in selecting the appropriate fuel type for your car. It will specify whether your car requires gasoline, diesel, or another fuel type. This information is crucial as using the wrong fuel can negatively impact your vehicle's performance and even cause damage to the engine and other components. Therefore, taking a moment to check the fuel door sticker before refueling can save you from potential issues and costly repairs.
Octane ratings, commonly indicated on the fuel door sticker, are particularly important. Gasoline is available in different octane ratings, such as 87 (regular), 89 (mid-grade), and 91 or 93 (premium). While most cars perform well on regular unleaded gasoline with an octane rating of 87, some vehicles with high-performance or turbocharged engines may require higher octane fuel to prevent engine knocking or pinging during combustion.
It's worth noting that using a higher octane fuel than recommended does not necessarily enhance your car's performance or provide any additional benefits. Higher octane fuels are designed for engines with higher compression ratios that require greater knock resistance. Therefore, unless your car's manual or sticker specifies a higher octane rating, it is generally advisable to use the lowest recommended octane fuel.
In addition to the fuel door sticker, it is always a good idea to refer to your car's owner's manual. The manual will provide detailed information about your vehicle's specific fuel requirements, including the recommended octane rating. Consulting both the fuel door sticker and the owner's manual ensures that you have the correct information to make informed decisions when fueling your car.

Understand octane ratings
Understanding octane ratings is essential for maximising your vehicle's performance and fuel efficiency. Octane ratings are a measure of a fuel's ability to resist 'knock' or spontaneous combustion. The higher the octane number, the more stable the fuel and the greater its resistance to knocking or pinging during combustion.
The octane requirement of an engine depends on various factors, including the compression ratio, geometrical and mechanical considerations, and operating conditions. Most cars are designed to run efficiently on regular unleaded gasoline with an octane rating of 87. However, some car manufacturers have started recommending or requiring premium gasoline (a high-octane grade of fuel) for their vehicle models. It's important to note that using a higher octane fuel than recommended does not enhance your car's performance or provide any advantages.
To determine the appropriate octane rating for your car, you should always consult your owner's manual. The manual will typically specify the recommended octane rating for your vehicle. Additionally, you can find valuable information about your car's fuel needs by checking for a sticker inside the fuel door or near the gas cap, which often indicates the recommended fuel type and octane rating.
If you don't have access to your owner's manual, you can also check online by searching for the specific make, model, and year of your car. This will usually lead you to information from the manufacturer, including the recommended octane rating. It's important to use the correct octane rating to ensure optimal performance, prevent potential engine problems, and maximise fuel efficiency.
In summary, understanding octane ratings involves recognising that these numbers indicate a fuel's stability and resistance to knocking during combustion. By consulting your owner's manual or online sources, you can determine the recommended octane rating for your vehicle, which will help you make the right choice at the fuel pump.
