^{Drive up to almost any gas pump in the United States and you will see three fuel options. What do these mean?}

^{Most drivers choose the cheapest option or lowest grade fuel; however, others purchase the most expensive or highest grade because they assume it is best for their vehicle’s engine. If you are confused by the three buttons, don’t mistakenly pull up to the diesel pump because that’s a confusing territory, too. Basic knowledge of fuel types and grades is useful for any driver and will help you make decisions that will improve the function of your car. Below are the types of fuels available today, their characteristics, and their common uses.}

^{Types of Fuel for Cars}

^{1) Gasoline}

^{Gasoline is the most common automobile fuel and is used all over the world to power cars, motorcycles, scooters, boats, lawnmowers, and other machinery. It is a specialized fossil fuel made from petroleum. It is also important to note that hydrocarbons in gasoline and carbon dioxide from producing it contributes to pollution and smog. Despite this, you can find gas stations all over the place. Gas is commonly available in three octane ratings or “grades.” Grades are denoted by the research octane number (RON) and AKI of a specific formula. Stickers or labels will inform drivers which pump releases each grade. 87 AKI is generally the lowest octane rating and cheapest option. Next is mid-grade with 88-90 AKI. Lastly, premium or high-grade gasoline has an octane rating of 90-94 AKI. The different grades of fuel don’t burn the same way. The less octane, or the lower the grade, the faster and stronger it burns when pressurized. SUVs and sports cars run better on plus or premium (higher octane) since their motors produce more fuel compression for better drivability. But most vehicles function just fine on the lowest and cheapest gasoline option. You won’t realize a better fuel economy if you opt for plus or premium gas for a car that recommends regular gas.}

^{2) Diesel Fuel}

^{Diesel fuel is also made from petroleum but is refined using a different method than that used to create gasoline. Many large and industrial trucks use diesel fuel, as do transfer trucks and agricultural equipment. There are two types of diesel fuel, one specifically for automobiles and one for off-road vehicles. A resurgence of diesel-powered vehicles has taken place in the past few years because of the rising price of all fuels, including gasoline and diesel. Diesel-powered cars typically get better gas mileage or fuel efficiency than gasoline-powered vehicles. Also, some drivers feel that they get a better value for their money even if diesel is more expensive. Volkswagen is a well-known manufacturer of diesel cars.}

^{3) Bio-diesel}

^{Diesel fuel that is created using vegetable oils or animal fats is called bio-diesel. It can be made using soybean oil, lard, algae, and vegetable oils. Some inventive drivers have found ways to recycle used cooking oils into biodiesel that powers altered car engines.}

^{4) Ethanol
Although ethanol is not widely used as general automobile fuel, it is added to our common gasoline as an additive. Many car manufacturers are designing vehicles that can be powered by ethanol because it is a cost-effective fuel made from renewable resources like corn and sugarcane. If you are in the market for an ethanol-powered vehicle, there are a few car models that can run on 100 percent ethanol. Most cars these days run on gasoline, but others are increasing in popularity, especially battery powered vehicles. Make sure that you are purchasing the correct type of fuel for your vehicle for peak performance.}
