What does auto fuel STC mean?

FAA 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 you use aviation fuel in a car?

Again, the answer is no. While kerosene can certainly be a hazardous material, there is no danger that your vehicle will catch fire if its gas tank is filled with jet fuel. However, it will stall out, and it can do severe and costly damage to your engine.

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 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.

Can a Cessna run on unleaded gas?

All three Cessna models utilize engines manufactured by Lycoming Engines, a Textron Inc. business. Lycoming recently approved the use of unleaded and lower-leaded fuels after completion of a series of tests. The fuel is compatible for both new production and legacy Cessna piston aircraft.

What octane is Avgas?

100 octane
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.

What octane is Jet-A?

The octane ratings of AVGAS, a gasoline-based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.

Can I put 110 octane in my car?

Owner. EZ- Your engine is not set up to take advantage of 110 octane fuel, but it will definitely not cause your car to overheat. The higher the octane you use, up to a certain limit, the more resistant the fuel is to preignition/detonation/knocking, allowing an engine to run more ignition advance.

What 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.

Is Mogas and gasoline same?

MOGAS is commercial gasoline identical to that supplied to gas stations for automobile use.

How much does fuel cost for a Cessna 172?

The Cessna 172 burns about 7-9 gallons per hour with Avgas typically costing about $6 per gallon, hourly fuel costs for the Cessna Skylane run between $42 and $54 per hour.

What octane is race gas?

100 to 120 octane
The gasoline at a gas station ranges from 87 to 93 octane. Racing fuel ranges from 100 to 120 octane. Since racing engines operate with higher compression ratios, they need higher octane racing fuel to operate.

What octane is airplane fuel?

Why use auto fuel in STCs?

The use of auto fuel is the best thing that has happened to general aviation in the last three decades. 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.

How long does it take to add an STC to an engine?

An IA mechanic must “install” the STC by adding the new fuel placards and an engine placard. He then fills out a log book entry and form 337. The whole process takes approximately 30 minutes. No additional modification is required on this type of engine.

Can I use Avgas with the 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.

Can I use ethanol with the STCs?

Ethanol cannot be legally or safely used with the STCs. Fuel containing MTBE or ETBE is acceptable and approved. Fuel blended to D-439 or D-4814 without alcohol is acceptable and legal for use with the STCs. If your state does not require compliance to these specs, it does not necessarily mean that your fuel does not comply.
