While most cars being driven today take regular unleaded gasoline, there are some cars that take other types. There are also many cars that can use more than just one type of gasoline and the best way to tell is to read the manual or call the company that made your vehicle. Most people just assume that their vehicle has to have regular(cheap gas) unleaded gas and don’t really know the differences between the different types of gasoline that are available for use today. This article is going to explain the most common gasoline types.

Regular Unleaded

Regular Unleaded gas is also known as just unleaded.This type of gasoline is the most commonly used gasoline. Most cars you come across will use this type. When going to a gas station, you can tell that the gas is unleaded if it has the number 87 as that is the amount of octane in it. A great thing about this type of gas is that it’s about 15 to 20 cents cheaper than other types of gas. Another great thing about this type of gas is that, depending on the car, you can use it in place of premium. Not only will this end up saving a little bit of money but it also won’t hurt your vehicle.

Mid-Grade Plus

This type of gas is above regular but below premium. The octane rating on this type of gasoline is 89 and it actually isn’t used by too many people. Since this type of gas is in between regular and premium, the price is usually a little more expensive than regular gas but a little cheaper than premium. A lot of times, the price of mid-grade fuel is halfway between the prices of regular and premium. Something that a lot of people don’t                                                                    know is the way that mid-grade gas is made. Usually, regular gas and premium gas are pumped at the same time into the same holding tank. With that being said, this means that you could fill your gas tank halfway with regular gas then fill the other half with premium and not only will it be the same price as mid-grade, but it will also have the same type of gas that the actual mid-grade holding tank has.

Premium
This type of gasoline can have different levels of octane but is usually at least 91. This type of gas is more expensive than regular and mid-grade. Most of the time, this type of gasoline is used in more luxury vehicles, such as BMW and Mercedes. The reason for this is because luxury cars have high compression engines and this gas is required to prevent the engine from knocking. With that being said, these types of cars can usually use regular gas unless the manufacturer of the car says that it specifically needs premium gas. Something that most people believe is that premium gas is better for your engine because of the additives and better for gas mileage. While this might be true about the engine being cleaner, it’s not actually from the additives but from the higher octane level. Another thing that people believe is that using premium gas in cars that don’t require it will have bigger benefits and while this might be true, the benefits aren’t too much bigger than using regular gas, so avoid the cheap gas.

Diesel
Vehicles that use diesel fuel is different from others because they don’t have engines that need sparks for ignition. Diesel fuel is a little bit more expensive than regular fuel and is usually used in larger vehicles such as semi trucks and larger pickup trucks. The most common type of diesel fuel is a distilled version of petrol but there are other alternatives, such as biodiesel and gas to liquid diesel. While most diesel fuel is made from petrol, there are other things that it can be made from as well. Some of these things are: animal fat, natural gas, and the liquefying of coal. While smaller vehicles that use diesel have a much larger mile per gallon amount than small vehicles that use gasoline, the larger vehicles actually don’t. They difference in gas mileage for the bigger vehicles is actually 2 miles per gallon either way.

Racing Gasoline

This gasoline type is mainly used for vehicles that are used for racing. Depending on the type of racing, the gasoline type is going to be different. For example, drag racing uses nitrous, while IndyCar racing uses ethanol fuel, and Nascar uses leaded gasoline. Each type of gas is going to cost a different amount and the miles per gallon is going to vary as well. The reason these gas types are used for racing vehicles is because the octane level is much higher, often times being at least 100-110. Another reason why racing fuel is used in these types of vehicles is because they need the higher octane in order to keep their engines under control since they need a high performance and are usually ran hard. Racers want to make sure their engines keep that big push that doesn’t turn into more of a hard slam. It really keeps everything int tip top shape.

Conclusion 
As you can see, each of these gasoline types have very obvious differences. In terms of normal vehicles, you can use pretty much any of the 3 common gasoline types without there being too much of a difference. If you have a diesel vehicle, you want to make sure you use diesel so your diesel injectors and fuel pump don’t get ruined. If you are doing racing, you want to make sure you use the correct racing fuel in order to keep your car in good shape and at the top of its game. If you aren’t sure which type of fuel is best for your vehicle, you can either look in the drivers manual or call the manufacturer.
