What does auto fuel STC mean?

Supplemental Type Certificate
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.

Can auto fuel be used in an airplane?

Automotive gasoline – known as mogas or autogas among aviators – that does not contain ethanol may be used in certified aircraft that have a Supplemental Type Certificate for automotive gasoline, as well as in experimental aircraft and ultralight aircraft.

What is AvGas used for?

Avgas is a specialized fuel used to power piston engine aircraft.

What is mogas fuel?

Mogas (also called autogas) is lead-free, ethanol-free gasoline that meets ASTM D4814 specifications, which includes most automotive fuel. Mogas has been an FAA-approved aviation fuel since 1982, when the first mogas STCs were approved. Some 110 public airports currently offer mogas, as shown at www.FlyUnleaded.com.

Is Mogas ethanol free?

A publication for antique car buffs is reporting the Environmental Protection Agency is intent on ending the production of ethanol-free gasoline, known in aviation as Mogas. But there are blends that have 15 percent or more ethanol and can be used in so-called flex fuel vehicles.

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. These have been developed by the Aviation Industry for Avgas to ensure that it is fit for flight operations and reaches the aircraft in good condition.

Is aviation fuel good for small engines?

The good news is you can purchase gasoline for your small engines that doesn’t contain ethanol. The best aviation gas to get for your small engine would be a low-lead one with an octane rating of 100 or slightly less. This works great with small engines with carburetors.

Is jet fuel the same as kerosene?

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 is a similar kerosene fuel type that is normally available only in the U.S.

What gas do old cars use?

In short, buy ethanol-free gas if you can, and buy gas with sufficient octane that your car doesn’t knock. If you’re forced to choose, take the higher octane to prevent knocking. But if the car doesn’t knock, go with the ethanol-free gas.

How long is Mogas good for?

about six months
For Mogas, a normal life is about six months. But both of these can be shortened or lengthened by many factors. For the storage life of fuel with ethanol, there is no good answer. Under ideal conditions, it should last six months.

What Colour is Mogas?

Avgas 100. The standard high-octane fuel for aviation piston engines. It has a high lead content and is dyed green. There are two major specifications for Avgas 100: the ASTM D910 and UK DEF STAN 91-090.

Does aviation fuel have ethanol?

Neither mogas nor avgas contain ethanol because it can be nasty for plane engines. Ethanol absorbs water from the air, and an ethanol-water mixture corrodes fuel lines, gaskets, and other parts.

What are the benefits of an auto fuel STC?

In an era when the cost of flying has inflated to ridiculously high levels, Auto Fuel STCs have done more than anything else to reduce costs. Enjoy the following benefits when you install an Auto Fuel STC on your aircraft: The price difference between auto fuel (mogas) and aviation fuel (avgas) is significant.

Can you use Avgas with auto fuel STC?

Installing the Auto Fuel STC does not restrict you to using only auto fuel. Avgas can still be used, and it can be mixed with auto fuel if you wish. Without the STC, you are limited to only avgas.

What kind of fuel does a low compression STC use?

The low compression Auto Fuel STCs approve the use of 87 and 88 Anti-Knock Index (AKI) automotive fuel, regular or unleaded. These are minimum numbers, so you can also use premium fuel. High compression STCs require the use of 91 AKI (minimum) premium unleaded or leaded automotive fuel.

Do you need STC for gravity feed fuel?

Generally speaking when these engines are mounted in an airframe equipped with a gravity feed fuel system (no fuel pumps), installation of the STCs consists only of paperwork and placards, with no modifications made. Some people then reason why buy an STC if it’s only paperwork and placards.
