Not if it runs on 100ll

edit:"You might try kerosene. Avgas is mainly highly refined kerosene, "
Terracinese, you are soooooo wrong!!
Aviation turbine fuels are used for powering jet and turbo-prop engined aircraft and are not to be confused with Avgas. Outside former communist areas, there are currently two main grades of turbine fuel in use in civil commercial aviation : Jet A-1 and Jet A, both are kerosene type fuels. There is another grade of jet fuel, Jet B which is a wide cut kerosene (a blend of gasoline and kerosene) but it is rarely used except in very cold climates.


Avgas is gasoline fuel for reciprocating piston engine aircraft and is not to be confused with jet fuel. As with all gasolines, avgas is very volatile and is extremely flammable at normal operating temperatures.
Avgas grades are defined primarily by their octane rating. Two ratings are applied to aviation gasolines (the lean mixture rating and the rich mixture rating) which results in a multiple numbering system e.g. Avgas 100/130 (in this case the lean mixture performance rating is 100 and the rich mixture rating is 130).

In the past, there were many different grades of aviation gasoline in general use e.g. 80/87, 91/96, 100/130,108/135 and 115/145. However, with decreasing demand these have been rationalised down to one principle grade, Avgas 100/130. (To avoid confusion and to attempt to eliminate errors in handling aviation gasoline, it is common practice to designate the grade by just the lean mixture performance, i.e. Avgas 100/130 becomes Avgas 100). More recently, an additional grade was introduced to allow one fuel to be used in engines originally designed for grades with lower lead contents: this grade is called Avgas 100LL, the LL standing for 'low lead'.

With an additive, diesel engines (automotive) can run on Jet A. All Jet A is, is highly refined diesel fuel. You can take a match and drop it in a pan of Jet A and the match would go out. While at work, we had to do fire extinguisher training and the instructor learned this. He went through 5 or 6 matches before getting a propane torch to light the pan of Jet A. It has a very high flash point and burns much slower compared to Avgas.

Avgas is also known as 100 low lead (100LL). It is just like leaded car gas with 100 octane level. Very often, we will get guys coming in with gas cans to fill up for their dirt bikes and snowmobiles because of the high octane level. You wouldn't want to try the match trick with Avgas, it has a low flash point and would more than likely explode.

To answer your question, if you have the standard horizontally opposed piston engine, diesel fuel would not work. The spark plugs would have trouble igniting the fuel and it would be very costly to get it out of your engine. If for some reason you have a turbine powered 172, you might be able to use auto diesel but I wouldn't recommed it. I cant see it being very good for your engine. It would smoke an old school bus and would probably cause so much build-up in your turbine, that you would have an engine failure. Your best bet is to check your Flight Manual for substitute fuel recommendations.

You have a 172 and the answer is NO. You need 100LL. Jet fuel has different combustion properties. You can put jet fuel in a diesel engine, but not diesel fuel in a normaly aspirated engine. Your airplane depends on the compression of the avgas, and then the spark to ignite it. Diesel fuel doesnt need a spark to combust, your engine however couldnt sqeeze it tight enough to combust. So no dont do it.

No. A piston powered airplane is designed to run on 100LL or 100 octane low-lead fuel. In an emergency, you COULD use automotive gas, but I wouldn't.

A piston aircraft engine WILL NOT RUN on diesel. It would be like trying to burn jet fuel. It won't work.

(There are diesel piston engines slowly making their way to market now, but they are fairly far off for many of us)

If the airplane is equipped with the engine it came with from the factory: NO.
Cutlass RG came with O-360 Lycoming that will only burn 100LL.
You might get by with 93 octane unleaded, if you could find some of the bottled lead additive to jack up the octane, but I don't think you can find it anymore.
At any rate, there is no substitute for 100LL.

You didn't state whether you wanted to burn it as fuel or carry it on board.
No you cannot put diesel fuel in instead of av gas. Diamond aircraft has one twin that can run on either fuel but it is set up for it. Diesel would destroy the engine as it burns differently than av gas.
If you want to carry fuel on board there are regulations.as to the transport of dangerous fuels.

Either way each is not recommended.

hi here in europe we have some piston engines in research that should be diesel only :) only jet operable with diesel as fuel is sukhoi 25, in emergency, but that's merely a flying armor anyway. do not feed piston engined aircraft with diesel,you won't try this with your car as well

you know about Murphy's law? what will go wrong will go wrong at the worst time possible. anyways, don't think you want to stick that diesel in the wrong fuel tank, your gonna hear some hardcore detonation from the carbon residues building up in those piston aircraft and next think you know... emergency landing...that is if your still alive of course

It could not put diesel engine just rpm and HP too low. The air plane need big Horse Power especialy on propeler plane

not unless its a jet which lists diesel fuel as an approved alternative fuel
