1 Answer. Show activity on this post. The sweet smell of 100LL AvGas is due in large part—if not entirely—to the additive Tetraethyllead (TEL). TEL is included in the formulation of 100LL as an anti-detonation additive, octane booster, and lubricant.
What does aviation fuel smell like?
Avgas 100LL smells like gasoline (a little different than what you pump into your car, but similar). Jet-A smells like kerosene (not quite "like diesel", but definitely not like gasoline).
Why does aviation fuel smell good?
Jet-A1 is refined kerosene, which has a distinctive smell which some find unpleasant and others not. Aviation Gasoline (AVGAS) has many "aromatic" hydrocarbons to boost octane which are called aromatic because of their distinctive odors.
How toxic is avgas?
All forms of lead are toxic if inhaled or ingested. Lead can affect human health in several ways, including effects on the nervous system, red blood cells and cardiovascular and immune systems.
Is avgas same as Jet A-1?
Avgas is used for piston-engine aircraft, and Jet A1 (as you may see on tankers at airports) for jet engines.
31 related questions foundWhat octane is 100LL avgas?
Key points: -100LL is not 100 octane as we rate it for pump gas (R+M/2). It is actually ~96 octane by that measure.
Is avgas leaded or unleaded?
The most common and reliable type of avgas is 100 octane Low Lead, also known as 100LL. This leaded fuel contains tetra-ethyl-lead (TEL), which is an additive used to prevent engine damage at higher power settings.
Can you use avgas in your car?
Using leaded avgas in a modern car would ruin components such as the catalytic converter. Conversely, Jet-A wouldn't work in a gas engine.
Can you get lead poisoning from avgas?
Because of the risk of lead poisoning from avgas, environmental groups have pressured the U.S. EPA to take action to reduce lead emissions from aviation fuel.
What does jet fuel exhaust smell like?
“Instead, they are typically described as smelling like dirty socks/smelly feet, foul, or musty.” American's 737 operations manual uses similar terms for engine oil at high temperatures: “Sweat, locker room, dirty sock, rancid cheese, wet dog, burning rubber, musty, sour milk, (fresh oil) sweet, mild irritation to eyes ...
What does kerosene smell like?
Kerosene smells much more like diesel or home heating oil it is not nearly as crisp a smell as gas.
What is kerosene used for?
It is obtained from petroleum and is used for burning in kerosene lamps and domestic heaters or furnaces, as a fuel or fuel component for jet engines, and as a solvent for greases and insecticides.
Is bleed air toxic?
Known as bleed air, it is safe, unless there is a mechanical issue — a faulty seal, for instance. When that happens, heated jet engine oil can leak into the air supply, potentially releasing toxic gases into the plane.
Why do I smell kerosene in my house?
The most common cause of a kerosene smell in the house is the presence of oil or paint. Natural gas can be found in the air from your stove, water boiler, etc. It has an odor like that of kerosene. You should thoroughly air out your house.

Can I run avgas in my snowmobile?
Yep I have run a lot of avgas through my sleds. I usually mix it about 50% with pump gas 91. It works great in the yard equipment as well.
Can you mix avgas with regular gas?
100LL mixes just fine with pump gas. It really is no different than race gas, has similar smell. My best understanding is a difference in vapor pressure so it does not vapor lock when used in an airplane. Not an issue for an automtive engine.
Can you run avgas in a dirt bike?
AvGas is suitable for certain engines, namely ones that do not contain oxygen sensors or catalytic converters. It also is alright to use in dirt bikes that are rebuilt frequently, because the build-up of lead is not a problem.
Why do we still use lead on avgas?
General aviation's need for a high-octane fuel to power high-compression piston engines required avgas makers to add tetraethyl lead before delivery to prevent damaging engine knock, or detonation, that could result in engine damage.
What is avgas made from?
Today, commercial aircraft use jet fuel or Aviation Turbine Fuel (ATF), a specific power source. The two most common fuels are Jet A and Jet A-1. While the former is used almost exclusively in the US, the latter is used globally. Both are made up of kerosene, a product of extremely refined oil.
Does 100LL avgas go bad?
A straight hydrocarbon fuel like 100LL and autogas do not lose octane with time. For example, iso-octane has a research and motor octane number of 100 and, if stored properly and not contaminated, it will have an octane of 100 for many years.
Does avgas go off?
The short answer is that, under most conditions, the shelf life of avgas is about one year.
Is 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.
Why is avgas so expensive?
It's much higher grade, so it costs more. It's a specialist fuel made in much less quantities than other fuels, so a premium is added to ensure a profit.
