What is an auto fuel STC?

What is an auto fuel STC?

The EAA type certificate program resulted in an FAA Supplemental Type Certificate (STC) being issued for the use of automobile gasoline, rather than aviation gasoline, in the Cessna 150 aircraft, powered by a Continental O-200 engine.

What grade’s of aviation fuel is are available for use?

Types of avgas. There are two main avgas grades (100 and 100LL low lead) used in the general aviation community. In each of these types, the numbers represent the octane rating. There are also other types of avgas that are either rarely used or no longer in production.

What is the difference between Avgas and Mogas?

In a nutshell, Mogas which is otherwise known as motor gasoline, is used by ground vehicles, while Avgas is specifically developed for aircraft use. Part of the process of supplying a dedicated aviation fuel involves strict specification and quality control measures.

What is aviation fuel octane rating?

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 type of fuel do Cessnas use?

91-octane unleaded
Owners of Cessna 172s and 182s can use 91-octane unleaded (91UL), 94UL, or 100VLL (very low lead) fuel in their aircraft wherever it is available, according to officials with Cessna’s parent company, Textron Aviation.

Can a Cessna 150 use auto gas?

On the basis of these tests, FAA approval has been given for the use of unleaded regular automobile gasoline for all Cessna 150 airplanes powered with Teledyne Continental Motors 100 hp. engines. No changes were required to the airframe, engine or operation of the aircraft.

Can you run a car on aviation fuel?

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. Although, I wouldn’t recommend running a jet on diesel.

What are the two categories of aviation fuel?

Shell Aviation fuels fall into two basic groups:

• Aviation gasoline – Used in reciprocating or piston engines.
• Aviation turbine fuels (jet fuels) – Used in turbo-fan, turbo-jet, and turbo-prop engines.

Can you mix Mogas and avgas?

If the plane is approved for Mogas by STC you can mix Avgas and Mogas.

What octane is 100LL?

100 octane
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.

What is the difference between car fuel and airplane fuel?

Gasoline consists of hydrocarbons that contain anywhere from 7 to 11 carbon atoms with hydrogen molecules attached. Jet fuel, on the other hand, contains hydrocarbons more in the range of 12 to 15 carbon atoms. In more colloquial terminology, jet fuel is made up mostly of kerosene.

Do Cessnas use regular gas?

Owners of Cessna 172s and 182s can use 91-octane unleaded (91UL), 94UL, or 100VLL (very low lead) fuel in their aircraft wherever it is available, according to officials with Cessna’s parent company, Textron Aviation.

What happens if you mix 100LL and 100?

If you mix two gasolines that are both rated 100, even if they got there by the addition of different amounts of lead, the result is still 100. Also, the amount of lead in the standards for both 100/130 and 100LL is a maximum, not a fixed value.

When May automotive fuel be used in an aircraft engine?

Engines that are approved for operation on 80/87 grade aviation fuel, or normally aspirated engines that have a compression ratio of approximately 7.2:1 or less, may operate satisfactorily on automobile gasoline.

Can you use car gas in an airplane?

Problems Can Occur Vapor lock is a real issue when using autogas in aircraft engines, particularly at high altitudes on hot days — after all, it’s made for use at sea level, or at most lower altitudes. Cars don’t get up into the flight levels!

Will a diesel engine run on aviation fuel?

Yes, and diesel cars can run on aviation jet fuel.

What is the best fuel for aircraft?

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. Jet A-1 has a flash point higher than 38°C and a freezing point of -47°C.

What is green aviation fuel?

Sustainable aviation fuel (SAF) is made from sustainable resources that can be mixed with any fossil jet fuel to reduce emissions. It is a ‘drop-in’ fuel meaning it can be added with no changes needed to the aircraft or infrastructure.

Does AVgas burn hotter?

The first is that a two stroke motor will run hotter with AVgas. If anything, the opposite is the case. 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.
