Understanding Different Types of Gasoline

Which Is Best for Your Vehicle?

When it comes to fueling your vehicle, not all gasoline is created equal. The type of gasoline you choose can impact your car's performance, fuel efficiency, and even the longevity of your engine. Here at Victory Auto Body and Paint in Burbank, California, we understand the importance of using the right fuel, so let’s dive into the different types of gasoline and what they mean for your vehicle.

1. Regular Unleaded Gasoline (87 Octane)
This is the most common type of gasoline, with an octane rating of 87. It’s typically the least expensive and is suitable for most cars on the road today. If your vehicle’s manufacturer recommends regular unleaded, this is likely the best option. Regular unleaded gasoline provides good fuel efficiency and adequate performance for most standard vehicles. However, using regular gasoline in a car designed for higher-octane fuel can lead to engine knocking and decreased efficiency.

2. Mid-Grade Gasoline (89 Octane)
Mid-grade gasoline, also known as “plus” or “special,” has an octane rating of around 89. It’s a step up from regular unleaded and is often recommended for vehicles that benefit from slightly higher performance. Cars that may experience engine knocking with regular gasoline might run more smoothly with mid-grade. While it can improve performance in certain vehicles, for most cars, the benefits are marginal compared to regular gasoline.

3. Premium Gasoline (91-94 Octane)
Premium gasoline, with octane ratings typically between 91 and 94, is designed for high-performance engines. Luxury cars, sports cars, and other high-performance vehicles often recommend or require premium fuel. The higher octane rating prevents knocking and optimizes performance in engines that operate at higher compression ratios. While premium gasoline is more expensive, using it in a car designed for it can improve acceleration and fuel economy.

4. Ethanol-Blended Fuels (E10, E15, E85)
Ethanol-blended fuels combine gasoline with ethanol, a renewable biofuel made from corn or sugarcane. The most common blend is E10 (10% ethanol), which is approved for nearly all gasoline vehicles. E15 (15% ethanol) is less common but is suitable for many modern cars. E85, or flex-fuel, contains up to 85% ethanol and is designed for flex-fuel vehicles. Ethanol can be beneficial for reducing emissions, but it generally provides lower fuel efficiency compared to pure gasoline.

5. Non-Ethanol Gasoline
While ethanol-blended fuels are common, some drivers seek out non-ethanol gasoline, especially for classic cars, small engines, or boats. Non-ethanol gasoline can improve fuel efficiency and reduce the risk of corrosion in engines that are not used frequently. However, non-ethanol gasoline is harder to find and often more expensive.

6. Top-Tier Gasoline
Some gas stations offer “top-tier” gasoline, which is regular, mid-grade, or premium fuel that includes additional detergents and additives. These additives help to clean the engine, reduce carbon deposits, and improve overall performance. Top-tier gasoline can be a good choice if you want to maintain engine cleanliness and efficiency.

Choosing the Right Fuel for Your Vehicle
To choose the right type of gasoline for your car, start by consulting your owner’s manual. This will outline the recommended octane rating for optimal performance. If your car requires premium gasoline, it’s best not to substitute it with a lower-octane fuel, as this can lead to engine knocking and reduced efficiency. Additionally, consider using top-tier gasoline periodically, especially if you want to keep your engine as clean as possible.
