How Does 100ll Aviation Fuel Compare With Racing Gas?

What is the difference between avgas and race fuel?

AvGas has a lower specific gravity than most racing gasolines. This means that if a racer tries AvGas and has not re-jetted, he can burn a piston because the air- fuel ratio is too lean and/or the engine detonated. To make a good comparison between two gasolines, the air- fuel mixtures must be the same.

How much octane is 100LL?

100LL has a minimum MON of 99.6. AKI is the octane rating used to grade all U.S. automotive gasoline (typical values at the pump can include 87, 89, 91, and 93), and also the 93UL fuel from Airworthy AutoGas. The minimum AKI of UL94, as sold by Swift Fuels, is 98.0.

What is the octane rating of Avgas?

They Have Different Octane Ratings The most common avgas is 100 octane, which is a measure of the fuel’s ability to resist premature detonation or “knock.” Avgas is also available at other octanes such as 87 and 130, but they are rare today. At the pump, you’ll find gas ranging from 87 to 93 octane for automotive use.

What is the difference between 100LL and Jet A fuel?

Jet -A is suited for turbine engines, but can also be burned in other compression-ignition piston engines like diesel can. 100LL is the most widely available aviation fuel because it works in the widest range of engines. The grade or octane rating of aviation gasoline is identified by colored dyes added to the blend.

Can I put jet fuel in my car?

Jet fuel can actually be used in cars, but only in diesel engines. Kerosene jet fuel and diesel are actually similar enough to allow for cross-functionality and would provide a similar performance. Both are derived from crude oil, and both run their respective engines on combustion.

Does AVgas burn hotter?

The first is that a two stroke motor will run hotter with AVgas. The higher octane of AVgas makes the fuel burn slower and more efficiently. Also the lead in AVgas helps to dissipate heat and acts as a lubricant.

Can you mix 100 and 100LL?

If you mix 100 /130 and 100LL you get greenish-blue. I guess they didn’t find it necessary to make the dyes cancel each other out since airplanes originally designed for 100 /130 would also run on 100LL.

Why is Avgas so expensive?

This fuel is expensive for a number of reasons: 100LL fuel has many more “aromatic” hydrocarbons than mogas (auto fuel) in order to increase the octane levels and prevent fuel from vaporizing in your lines at high altitude. It’s much higher grade, so it costs more.

How many 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.

Will 110 octane hurt my car?

High octane race fuel is sort of the same way. 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.

Can I use 100 octane in my car?

Yep running on pure octane will not hurt the car. It will have slightly less power and fewer MPG but will run just fine. High compression engines need high octane fuel. Putting high octane fuel into a low compression engine will not make it a high compression engine.

Does higher octane gas burn hotter or cooler?

Higher – octane fuel does not burn hotter. It will not clean out deposits from an engine combustion chamber. And it will not provide any higher fuel economy. But an engine’s octane rating can change over time.

How much is jet fuel per gallon today?

170.8 Cents (US dollars) per Gallon.

Is jet fuel a kerosene?

Jet fuel ( Jet A-1 type aviation fuel, also called JP-1A) is used globally in the turbine engines ( jet engines, turboprops) in civil aviation. This is a carefully refined, light petroleum. The fuel type is kerosene.

What Colour is jet fuel?

Jet fuel is a clear to straw-colored fuel, based on either an unleaded kerosene ( Jet A-1), or a naphtha-kerosene blend ( Jet B). Similar to diesel fuel, it can be used in either compression ignition engines or turbine engines.
