When Fueling an aircraft powered by a piston engine it is acceptable to use a blend of 100 LL and Jet A fuel.?
C. True only if the aircraft is a military aircraft
D. True if it is the only fuel available.

The only correct answer is B. False, piston engine is only designed to run on the proper fuel. If you mix it with Jet A it will cause detonation and cease the engine.Source(s): Reference FAA Powerplant Handbook FAA-H-8083-32A Chapter 2.

B.False,unless a diesel engine.
Jet B is a mix of kero and AvGas for very cold climates, but for Jets Only..

False. Jet A fuel is diesel fuel/karosene/heating oil type fuel. The octane is no where near high enough to run a high power piston engine.

You can fuel a DIAMOND DA-62 with JET-A because it runs diesel engines.

False. Jet fuel is basically Kerosene and will cause a crash in a piston engine aircraft. You can only use jet fuel in turboprop and or jet engines, any turbine engines.

Jet Fuel in a PISTON engine (even mixed) is an FAA / NTSB accident report which will soon occur. NEVER put jet fuel of any amount in a true piston aircraft.

Jet-A fuel is basically kerosene. The only piston engines it can be used in are those which run on the Diesel cycle. Such as the Cessna Turbo Skylane JT-A.
100LL is aviation grade petroleum gasoline.
Diesel engines don’t run on gasoline. They can manage a tiny percentage mixed with the diesel fuel, but that would be really stupid on any aeroplane unless specifically recommended by the manufacturer such as in very low temperatures. When used that way it’s done to stop the diesel fuel from turning to wax. I know of no manufacturers of Diesel piston engines for aeronautical usage who recommend that except for a few old Soviet-era aircraft manufactured during the Cold War era.
Gasoline engines cannot run on diesel fuel. Even a tiny percentage mixed with gasoline will cause excessive smoking and can cause carbon build-up in the cylinder heads.
