Each if these is discussed in separate steps below.
Conventional gasoline. This is the most popular and widely available type of gasoline in the United States. This type of gas is sold only in areas where the air quality is acceptable or satisfactory. Conventional gasoline is formulated to vaporize more slowly during the hot, summer season, helping to reduce the presence of smog in the environment.

California Phase 2 reformulated gasoline is mandated for use in the state of California since 1996. This type of reformulated gas has a different constitution than regular reformulated gas and is considered much cleaner than the latter.

Chemical which are rich in oxygen, such as ether, tertiary butyl and methyl are added to gasoline to make this fuel. Gasohol is another type of oxygenated gasoline. This is a mix of ethanol and gasoline in a 10:90 proportion. Gasohol is also referred to by various other names such as Unleaded Plus, E-10 or Super Unleaded Plus Ethanol.
