Coleman fuel for a gasser

It can be used but the octane rating is very low I believe. It is supposed to be unleaded gas without any of the additives needed for cars. Same thing as white gas sold for lanterns, etc.

Naptha is a very volatile petroleum product used for lanterns and pressurized coleman type stoves. If you like your looks, I'd suggest you stay away from using it other than its suggested use. Someone once said that ignorance is bliss...however in this case ignorance can be deadly. Be careful with Naptha.

From what I have heard, those additives are to slow down combustion. Might not be good for ANY engine.

Maynard Hill used Coleman fuel for the transatlantic flight.

I'm sure he added other things to it and took good care not to burn his face off with it.

Going from memory here, (dangerous territory ;-) ) Naptha (spelled naphtha) Is basically a solvent

or according to the dictionary , Any of several highly volatile, flammable liquid mixtures of hydrocarbons distilled from petroleum, coal tar, and natural gas and used as fuel, as solvents, and in making various chemicals

In other words, it could be almost any combination of "stuff" It would burn, It might be ok, but,,,,

used this from time to time in old two-cycle lawnmowers as a kid when we ran out of white gas. made them run like thunder till they sucked a piston.

That's the fuel used by Maynard Hill in his record breaking flights including the one that crossed the Atlantic last year.

According to the API petroleum naptha is a range of hydrocarbons between that of light gas and kerosene. Includes paint solvents and avgas.

The current unleaded automotive gas in Europe is safe for use in Coleman appliances. There also is a non-smelling gas available from garden appliance sellers, which I believe is the Coleman gas you guys refer to. Is is a special higher octane brew for field and woods workers with chain saws and weed whackers, that keeps the environment a bit more user friendly for the quadrupla-podes that share this globe with us.

Lead additives to raise the octane value do slow down combustion as well. In doing so, knock (explosive self-ignition) is prevented in remote combustion chamber pockets in front of the flame pressure wave. Slowing down combustion speed is not necessarily bad, as long as it is still fast enough to finish the combustion process in time. Ever noticed the long flames from Dragster Nitro engine exhaust pipes? That mixture was still burning when the valves opened, yet provides ample power.

Guess I worded it incorrectly. What I meant is that using fuel without those additives might ruin an engine due to the pre-ignition.

Didn't see the start of this thread, but the originator might query Maynard Hill on the subject of Coleman fuel in a model 2C engine.

Fred, I strongly suspect that the fuel used by Hill was not straight Coleman but something blended with the Coleman gas as its base. I have a pretty good idea the oil used since local tests showed consumption figures of over 20 minutes per ounce of fuel over 10 years ago, but what else was used (if anything) will probably remain his 'trade secret' for a while longer.

That's what he reports, too.

I imagine. He's paid his dues--thousands and thousands of hours of mind-numbing test flights. He didn't get the record without first making sure his brew was true.

Obliviously there was oil added, since Coleman lanterns/stoves don't need lubrication.
