What is the difference in grades of gasoline?

The main differences in grades of gasoline are the octane level and type of additives included in the gasoline.  A gasoline's octane rating measures its ability to prevent engine knocking.  Powerful engines exert more pressure on the major components of your car, including head gaskets, spark plugs and pistons.  Also, higher-grade gasoline can include more additives which work to boost the octane level.  General recommendations for which type of gasoline to use can usually be found in the owner's manual of your vehicle.
 
Additionally, the West Virginia Division of Labor's Weights & Measures Section is responsible for overseeing and verifying the fuels being offered by state gas stations.  The organization's duties include: calibration of pumps, tanks and meters; assuring fuel quality; and, verification of scales, registers, scanners and weighing devices for accuracy.

The major oil companies that supply West Virginia's fuel outlets include:  British Petroleum (BP), CITGO Petroleum, ExxonMobil and Marathon Petroleum Company.
