Learning More About AV Gas as a Common Aviation Fuel


There are several types of fuel that can be used by aircraft depending on which kind of aircraft it is. For instance, Jets use diesel fuels while there are other aircrafts that use AV gas or Mogas. This article presents an insight into the AV gas properties and benefits.

Aviation gasoline or AV gas is a type of fuel that most piston-powered aircrafts use. It is a kind of aircraft fuel that is very common and has a history of usage. The main purpose of the AV gas is to reciprocate piston engines. There are several additives that can be used on AV gas including static dissipaters, antiknock, tetraethyl, icing inhibitors, oxidation inhibitors, corrosion inhibitors, and metal deactivators.

At normal temperatures, this type of gas is very volatile and highly flammable. For this reason, it is important to handle the gas properly and safely. The two main types of ratings for AV gas are lean and rich mixture ratings which are the octane ratings that define the various grades of AV gas.

Gasoline fuels are mostly formed from hydrocarbons with the most popular being Iso-octane. Iso-octane has excellent antiknock properties. The fuels that possess similar antiknock properties to those of iso-octane are given a rating of 100. Heptane is another example of hydrocarbons which can also be applied to fuel octane rating once it is mixed with varying amounts of iso-octyne.

Today, additions of lead and other replacements, increase the engine’s power prior to detonation. This means that the addition of lead will improve the performance of the engine. One other crucial element of improved engine power is the fuels air ratio.

Contrary to what is believed by many, converting to the use of fuel with high octane ratings alone without changing anything else is not the only requirement of improving an engine’s power. High octane rated fuels are essential in high compression engines due to fact that they help to delay the probability of knocking or detonation at high power settings.

Another classification of AV gas is the 100LL, which has at least a 0.5 gr lead per liter of fuel and is considered a low lead fuel version. We also have the AV gas 82UL, which is unleaded and is mostly used in the low compression ratio engines.

In previous times, AV gas had a number of grades in use but today they have been reduced to only the AV 100.

While adding lead to aviation fuel might be good in enhancing the performance of an engine during combustion, unleaded fuels are recommended for reasons relating to health. However, lead pollution is mostly caused by the millions of cars that use lead fuel.
