How much does a gallon of 100LL fuel weigh?

Average cost of 100LL in the U.S., April 2017: $4.75/gal. Density of avgas (all grades) at 15° C: 6.01 lbs./U.S. gal. Density of avgas (all grades) at -40° C: 6.41 lbs./U.S. gal.

What is the octane rating of 100LL?

Grade 100LL has two milliliters of lead per gallon and is rated at 100 octane when the engine is leaned for cruise, and at 130 octane when the mixture is set at rich. The fuel is designated as “low lead” because the previous fuel with a 100/130 octane rating contained twice as much lead, four milliliters per gallon.

How much octane is avgas?

The Lean Mixture rating is 100 octane (15 octane higher than the comparable 85 MON for unleaded Mogas) but Avgas also has a Rich Mixture rating of 130 which allows higher supercharger boost pressures to be used without detonation occurring.

What is the weight of 1 gallon of avgas?

The standard weight for avgas is 6 lb per gallon.

How much does avgas weight per Litre?

We use approximately 0.7185kg for a litre of Avgas in our calculations.

Does 100LL avgas go bad?

The short answer is that, under most conditions, the shelf life of avgas is about one year. The second point is that the one year shelf life applies to avgas and not auto gas. If a pilot is using auto gas, he should make a serious effort to use all of the fuel supply within six months of purchase.

Can I mix AVgas with regular gas?

Yes, you can mix any of our race fuels. But remember – if your engine needs an unleaded fuel, you don’t want to mix leaded with unleaded. The percentage of the 100 octane fuel in the mix is 2/5 = 0.40 ( 40%).

Is 100LL avgas oxygenated?

AV Gas is oxygenated (BTW: this means it has some alcohol content – likely to be methanol) and it has a number of other additives (primarily de-icers and the like) that you probably don’t need in a race engine.

Is 91/96ul the same as 91 Mon aviation fuel?

Hjelmco still uses the lean/rich MON numbers to denote their fuel, thus Helmco’s 91/96UL would be the same as a 91 MON aviation fuel. To add to the confusion, most countries denote octane ratings for highway vehicles according to their RON (RON = Research Octane Number), except the US, which uses the Anti-Knock Index, AKI (AKI = (RON+MON)/2 ).

What is the difference between UL94 and 100LL gas?

UL94 has a minimum Motor octane number (MON, which is the octane rating employed for grading aviation gasoline) of 94.0. 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.

What is UL91 fuel?

UL91 is an unleaded aviation fuel approved by EASA (the European equivalent of the FAA) and now in production by France’s TOTAL. It is available at a handful of airfields in France, Germany, and the U.K.

What is the difference between aviation gasoline 100 and 100LL?

Aviation Gasoline 100LL (dyed blue) is a lower lead version of Aviation Gasoline 100 (0.56g lead/litre Max). It is also excellent for use in piston engine-powered private, commercial and military training aircraft.
