What are the types of race fuel?

The specialized NASCAR fuel is Sunoco Green E15, a 98 octane, unleaded fuel blend specifically engineered for high-performance engines and race cars. It’s called Green E15 because the racing fuel is actually green in color.

What race has the best gas?

Sunoco Standard is the most common choice as an entry level race fuel. Like all our race fuels, Standard is extremely stable and consistent. 100% gasoline, this leaded fuel offers 110 octane and can be used in carbureted applications from dirt bike to drag car.

What octane is race gas?

RACE GAS ULTRA is specifically designed for the requirements of very high compression, boosted or nitrous engines. ULTRA, when mixed with pump gasoline, will create racing fuel with octane between 108 and 112 r+m/2.

What fuel do race cars use?

Formula 1 racing still uses gasoline, but NASCAR and Indycar use a mixture of ethanol and gasoline. The fuel used in NASCAR vehicles is mostly gasoline with a small amount of ethanol (E15), and the fuel used in Indycar racing is mostly ethanol with a small amount of gasoline (E85).

What are the characteristics of different racing fuels?

Some fuel components add energy value to the fuel, some components are good burn accelerators and some components help vaporization. In general, energy values of different racing fuels are usually within three-to-five percent of each other. The burn rate and vaporization characteristics of different fuels are more likely to vary from fuel to fuel.

What can be used as an alternative race gas?

Methanol has been used as an alternative racing fuel to race gas for a number of years. One advantage of methanol is that it can be run very rich without a significant drop in power. This can allow the tuner to use the fuel as a cooling tool in the tuneup. The down side is that methanol can only pack about half of the energy found in gasoline.

Can you mix distilled race fuel with regular gas?

That means you can take 93 octane pump gas and mix it up to 105, replacing the need for distilled race fuel. There’s a mixing table on the back that lets you tailor your octane what you want and need. And the nice thing is you can mix it anywhere there’s a gas pump and it’s catalytic converter sage.

What does the octane rating on race gas mean?

Both produce undesirable pressure waves that affect performance and can result in engine damage. The sticker at the pump (or the octane rating provided by the race fuel manufacturer) expresses the “antiknock index” or (R+M/2) octane rating of the specific fuel.
