We know you care about what you put in your car or truck. That’s why we want to share some helpful information with you about the fuels we serve at Bucky’s.

Octane Levels
Gasoline is rated based on its octane level. Octane is the name of a key component in fuel known as hydrocarbon. 

An octane rating indicates the fuel's resistance to igniting or exploding. Fuel that’s quicker to ignite is not always the best for your vehicle's engine. Fuel that ignites too quickly might burn before your engine's pistons are in the right position to benefit from the fuel's explosion, which makes your engine work harder. Higher octane fuel ignites at the ideal time to improve both engine and fuel efficiency.   

Regular gas is rated 87 octane, mid-grade is rated 89 and premium is rated 91 - 93. Sometimes lower octane levels can cause pinging or knocking in certain cars. High-performance engines typically require higher octane fuel. Look below for the octane levels available at your local Bucky’s. 

Ethanol
Ethanol is a non-fossil fuel produced from crops like sugarcane and corn. It burns cleaner than regular gasoline and can be used in cars made after 1986. Unless labeled differently, the "ethanol blend" you see at the pump is composed of 10 percent ethanol and 90 percent gasoline.

E85 is an alternative fuel which contains 85 percent ethanol and only 15 percent gasoline. Besides its superior performance, ethanol burns cleaner than
gasoline. It is a completely renewable fuel that is environmentally friendly and enhances the nation's economy and energy independence. E85 is used in flexible fuel vehicles. Check with your vehicle manufacturer to see if your vehicle will run on E85.

Biodiesel
Ultra low sulfur diesel reduces pollution caused by diesel fumes. Biodiesel is a cleaner-burning diesel fuel made from a mixture of vegetable oil and diesel. B11 and B15 are ultra low sulfur diesel fuels blended with either 11 percent and 15 percent biodiesel.
