The only ones I know of have a diesel engine, there are none in production and there is no STC yet, but there are some experimentals that have them.
Most small engine aircraft such as Cessna's use a low leaded gas, usually blue in colour. But a lot of Cessna's can be converted to use regular gas that you would use in a car.
A Cessna plane's fuel consumption varies by model, but a typical Cessna 172 consumes about 8 to 10 gallons of fuel per hour. Larger models, like the Cessna 182, may use around 12 to 15 gallons per hour. Fuel efficiency can also be affected by factors such as weight, altitude, and flying conditions. Always refer to the specific aircraft's operating manual for precise consumption rates.
They run on 100LL avgas. It has a different price at every airport. Go to http://www.airnav.com, click on "Airports" then enter the name of the airport you want to use to learn the cost of fuel there.
Aviation fuel. In the past, they could run on 80LL or 100LL. 80LL is no longer available. Unleaded avgas types, such as 93UL, 94UL, 100LL, 102LL, etc. are still undergoing certification.
Avgas 100LL
If you use a f/a-18 about 10 seconds if you use a cessna 172 about 10 months
The Cessna 182 will use 11-12.5 gallons per hour.
A Cessna Citation's fuel consumption varies by model, but on average, it typically uses between 150 to 250 gallons of fuel per hour. For example, the Citation Jet (CJ) series may consume around 150 gallons per hour, while larger models like the Citation X can use up to 250 gallons. Factors such as flight conditions, weight, and cruising altitude can also influence fuel efficiency.
Sym Jet Euro 101cc Fuel
Jet fuel is high grade diesel so a jet fuel car would use high grade diesel fuel.
Avgas, or if it has a jet engine, it would use either Jet-A1 or Jet-B fuel.
Yes, it is safe to use a fan for this. Jet fuel is not easy to ignite.
