How-to Select the Appropriate Gasoline for your Car
Regular
Regular gas is the most basic and inexpensive type of unleaded gas. Most cars can use regular gas. This is the gas labeled 87 at the pumps. With advances in technology and ingredients, regular gas is the best and most affordable option for most drivers. Before selecting this gasoline for your vehicle, make sure to check to see if regular gasoline is recommended for your vehicle.
Mid-Grade
Mid-grade is the middle of the road gasoline. It is rare for an automaker to list this as the recommended gasoline for your vehicle. It does have more additives than regular gas, so you may notice a small increase in your fuel economy. One thing to note, if your engine makes a knocking noise when using regular gas, see if mid-grade gas solves the problem.
Premium
Premium gasoline is the highest quality of unleaded fuel. It is also the most expensive out of all of the types of unleaded gas. This will be anything above 91 at the gas station. Some luxury car brands recommend premium gas for their vehicles. If your car calls for premium gasoline for your vehicle, you should put premium in your it. If your car recommends premium but you do not use it, it could cause your engine to start knocking.
Diesel
Diesel is very different than regular gasoline. Do not put diesel into a vehicle that does not take diesel. This can cause issues with the car. Gas engines cannot combust diesel fuel, so the car would stop running. If this happens, the car will have to be towed to a shop, and all of the diesel fuel will have to be siphoned out of the vehicle.
Similarly, you should only put diesel into a car with a Diesel engine. Diesel is a lubricant in addition to being a fuel. If a diesel engine is using gasoline, the fuel-injector pump will not get enough lubrication. Make sure to keep this in mind when selecting gasoline for your vehicle.
As you can see, there are many types of gasoline for your vehicle. Be sure to pay attention and select the appropriate one for your vehicle, so that your engine will continue to run smoothly and without any issues.
