FUEL INFORMATION
There is a plethora of fuel types consumers need depending on their vehicle. Their costs are based on their percentage of octane, an element that helps engines burn fuel evenly.
Unleaded 87 Octane
Commonly called "regular", this is the cheapest and most commonly used fuel available. Contains up to 10% ethanol (a grain alcohol that is mixed with gasoline to reduce costs and emissions).
Unleaded 93 Octane
Commonly called "premium" or "super", this is the most expensive fuel used in everyday vehicles. Car models with high-power compression engines and superchargers require this fuel in order to function properly and boost fuel economy.
Unleaded 89 Octane
Commonly called "plus" or "mid-grade", this blend is made up of 65% 87 octane and 35% 93 octane and is priced as such. Retailers typically do not purchase this fuel as modern pumps are designed to blend the fuels automatically. Commonly used as a cheaper alternative to 93 in higher-power vehicles.
Ultra-Low Sulfur Diesel
This fuel is used worldwide for heavy-duty commercial and personal vehicles as well as off-road equipment. It is specially formulated with low sulfur content to reduce harmful effects to the environment.
Winterized ULSD
This is a variant of diesel that is used only from November to March. It contains a special additive with de-icer to keep diesel from gelling up and keep diesel vehicles running smoothly in cold temperatures. It is typically priced about 2.5¢ higher than standard ULSD.
