So Many Fuel Types. Which is Right for Your Car?
You've probably heard that most cars run with regular gas. But when you pull up to the pump at your local gas station around Minneapolis, MN, you see several different grades of gas and even different types of fuel. You might wonder why these different types and grades exist.
Using the right fuel type and grade is important because using the wrong fuel could potentially harm your car's engine.
Do You Know What Type of Gas To Use in Your Vehicle?
Like most things, keeping your vehicle running as it should start from the inside out. The type of gasoline you use to power your vehicle is one of several critical factors you should understand.
So exactly what types of gas does your car need? It's not as complicated as you may think, but there are some important components you need to understand about what fuel do cars use. Let's go over the different gasoline fuel types available, the purpose of each, and what type of petroleum is used in cars.
Different Fuel Types
Most cars run on gasoline, a refined petroleum distillate. Gasoline makes up the majority of options at your local gas station. However, there are other types of fuel as well.
Diesel is a different type of fuel obtained from crude oil. Some gas stations offer biodiesel, which comes from vegetable oil. Diesel is more expensive than gasoline, but it allows you to drive longer distances. It only works on vehicles designed to run on diesel fuel. If you use gasoline in a diesel engine, damage will likely occur as gasoline does not ignite properly and burns too quickly, resulting in a very low power output of the diesel engine.
When Can I Use Diesel Fuel
Many heavy-duty vehicles, including trucks that are equipped with a diesel engine, require the use of diesel fuel. Unlike regular fuel, diesel fuel is much denser, and when not used with the right vehicle, it can clog up your engine, causing substantial damage. The denser fuel can clog up your fuel system and interfere with the moving parts in your engine block. This happens because vehicles that have gas engines are not built to withstand the flow of diesel fuel.
If you ever accidentally put diesel fuel in your gas engine, it's important not to turn on your vehicle and to have it towed to your mechanic shop instead. turning over the engine can draw the diesel fuel into your engine block, making it harder to remove. The gas is removed, and diesel fuel is reintroduced to your diesel engine so that it can run as it should.
Today, many vehicles are built to run on alternative fuels. E85 is the most popular, a blend of 15% gasoline and 85% ethanol. It is less expensive than gasoline but leads to lower miles per gallon. Your car should have a decal or label identifying that it is E85 compatible (also known as flex fuel).
Other alternative fuels include liquefied petroleum gas, compressed natural gas, and liquid nitrogen. However, most vehicles are not built to accept these fuels.
Electric cars are gaining popularity. They run on electricity rather than gas. Before these cars can drive, the operator needs to be sure the battery is sufficiently charged. Some hybrid models use both a gasoline engine and an electric engine to power the vehicle. The combination is set up to allow the car to run as efficiently as possible.
How Gas Grades Work
Now that you understand the different fuel sources, let's explore the different fuel grades. But first, you need to understand why these different grades exist.
As you look at the different gas grades at the gas station, you'll notice that each grade has a number. This number is the octane rating, which measures how resistant the gasoline is to pre-ignition. When your gas ignites prematurely, you'll hear a rattling or knocking sound. This usually means you have used a lower octane-rated gasoline than is recommended for your car. The higher the octane rating, the more resistant the gas is to pre-ignition. Most cars are designed to combat the effects of pre-ignition.
Differences Between Gas Grades
Most cars' engines are built to withstand pre-ignition. Thus, regular gas is a perfectly acceptable choice. Some luxury and high-performance cars are equipped with higher compression engines, which are more likely to experience pre-ignition. These cars likely require a premium grade of gas. It is important that you read your owner's manual to confirm the octane rating required for your car. You should follow the factory recommendation, especially during the warranty period.
Typically, the higher the octane rating is in a fuel type, the better the fuel will perform in your vehicle. Higher octane gas will help alleviate that rattling or knocking sound, and you'll often find luxury or higher-end models requiring gas with a higher octane rating.
Choosing the wrong fuel type or grade can be a waste of money and could damage your car's engine. Manufacturers have spent significant testing time to determine the best fuel rating for your vehicle. The best bet for any car is to follow the manufacturer's recommendation when choosing the correct fuel for your car.
Different Types of Gas for Cars
When you stop at your local gas station, you'll likely see different fuel types for cars. As we mentioned, the octane ratings correlate to the quality of the gas.
Regular Gas
In many states, regular gas has an octane rating of 87. Most gas-powered vehicles on today's roadways require regular gas.
Premium Gas
Premium gas is reserved for vehicles with high-performing engines, such as sports cars or heavy-duty SUVs and pickup trucks. Some luxury automakers also require the use of premium gas, which is defined by an octane rating of 91 to 94.
Mid-Grade Gas
Mid-grade gas is a fuel with an octane rating between 89 and 90. It is more stable and, like regular gas, can be used in a variety of vehicles.
