What kind of gas do race cars use?

NASCAR engines burn 110-octane leaded gasoline. Indy cars burn pure methanol (a.k.a. wood alcohol, CH3OH). Top Fuel dragsters and funny cars burn nitromethane (CH3NO2).

What kind of gas do Nascar cars use?

The specialized NASCAR fuel is Sunoco Green E15, a 98 octane, unleaded fuel blend specifically engineered for high-performance engines and race cars.

What type of fuel does a race car 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 is the best fuel for racing?

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.

Do race cars use ethanol?

Most race car drivers prefer fuel that is methanol- or ethanol-based, and the reason is simple, really. Overall, alcohol-based fuel has a high octane rating which increases fuel efficiency. … Race car engines are different than those in a regular car. They are built to get more power out of fuels with less energy.

How many miles per gallon does a Nascar get?

At race speeds, Cup Series cars get 2 to 5 miles per gallon. Consumption under caution can be estimated at 14-18 mpg, based on comparable engines generally available to the public.

How many miles can a Nascar go on a tank of gas?

“In a single typical NASCAR race weekend, with more than 40 cars at high speeds for 500 miles (804 kilometers) — plus practice laps — at 5 mpg of gas, you’re looking at, conservatively, about 6,000 gallons (22,712 liters) of fuel [source: Finney].

Can you put race fuel in a normal car?

You can put some racing fuels in normal cars, but there is no real reason for you to do this. These fuels have higher octane ratings, so are designed to perform at higher temperatures and pressures. There is generally no noticeable performance gain when they are used to fuel consumer vehicles.

Is 100 octane fuel safe?

So, the moral of the story is; unless you have at least 12:1 compression (of more), do not run any 110 octane or higher race gas in it or you’ll go slower. If you have 10:1 – 11:1, you can run up to about 100 octane and be fine, but if you have in the 9:1 area, don’t even bother.

What octane is jet fuel?

The octane ratings of AVGAS, a gasoline-based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.

Whats better E85 or 93 octane?

E85 has an octane rating higher than that of regular gasoline’s typical rating of 87, or premium gasoline’s 91-93. This allows it to be used in higher-compression engines, which tend to produce more power per unit of displacement than their gasoline counterparts.

What is better E85 or race gas?

For gasoline, the stoichiometric value is 14.7:1, while E85 is 9.8:1. … As we mentioned earlier, and the reason for this test, is that E85 has a much higher octane rating than pump gas. In fact, the Rockett Brand E85 we tested rivaled the 114-octane race gas we compared it to.

Does race fuel make car faster?

ND] What advantages does racing fuel offer a car and engine? Race fuels can combust quickly and completely which prevents deposits and carbon from building up in the engine. Specially tailored properties like higher octane can allow an engine to use higher cylinder pressures and increase performance.

How much does race car fuel cost?

IMSA100 E10 fuel (90 percent gasoline, 10 percent ethanol) for TCR cars costs a whopping $12.90 per gallon or $696.60 for a drum.

Why do race cars use E85?

The motor racing industry has always preferred ethanol- or methanol-based fuels because these fuels tend to give performance vehicles more thermal efficiency and increased torque. In an advanced engine, E85 can improve the engine’s fuel consumption.

Can alcohol be used as fuel for cars?

3.3 Usage of alcohol fuels as gasohol

The 10% ethanol was blended with 90% gasoline is considered as Low-level ethanol blends like E10, it can be used in conventional vehicles. … In spark ignition engines, alcohol fuel can run at a much higher exhaust gas recirculation rates and with higher compression ratios [16].
