What is the octane for 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.

What happens if I accidentally put supreme gas in my car?

Engine computers can usually adjust their timing to account for the increased octane levels, so if you put premium gas in a regular car, you probably won't notice anything. However, some engines are not designed to burn higher-octane fuel, and you may see a reduction in performance and fuel economy.

What octane is kerosene?

Generally, the octane number (ON) of gasoline is in the range of 70–97, whereas the octane number of kerosene is much lower as only 20–50.

Why is jet fuel so cheap?

Jet-A is used in a much higher volume than 100LL. All the jet engine commercial aircraft each day burn through orders of magnitude more Jet-A than piston aircraft burn through 100LL. That means that there is a much higher production volume, and therefore a cost savings as a result.

What are the disadvantages of jet fuel?

However, compared to a kerosine-type fuel, wide-cut jet fuel was found to have operational disadvantages due to its higher volatility: Greater losses due to evaporation at high altitudes. Greater risk of fire during handling on the ground. Crashes of planes fueled with wide-cut fuel were less survivable.

Why is jet fuel so expensive?

Prices for the kerosene-based product have been climbing since December, propelled by diminished supplies after winter storms shut down refineries.
