Panel wipe as fuel?

[Aicchalmers]

Do they have an octane rating? Is it basically 'white gas' or Coleman fuel? Remember, camp stoves do not need high octane - it just needs to burn. It will also lack lead substitutes, as well as any protective additives. It also burns hotter than pump petrol. The Coleman version stateside has this for it's wiki page:

 

Though Coleman fuel has an octane rating of 50 to 55 and a flammability similar to gasoline, it has none of the additives found in modern gasoline and cannot be used as a substitute for gasoline, kerosene or diesel fuel in modern engines. Its high combustion temperature and lack of octane boosting additives like tetraethyllead will destroy engine valves, and its low octane rating would produce knocking.

From what I've read that's an issue for 4t engines but not 2t, since they don't have valves and also have the 2t oil mixed in for protective function.. I still think it's worth a shot in a junk saw!

Protecting valves is unimportant. Octane, however, is just as important to a 2t motor. Combustion temperatures are also very important(and the both will go hand in hand at causing detonation in your chainsaw). Adding 2t mix oil also lowers the octane of the fuel as well. So, you will be using even less than 50-55 octane, and burning a fuel that runs at higher temperatures. You can try it in a junk saw, if you like. That's your prerogative.

"Prerogative " good word Wes, glad to see the English language isn't completely lost in the US:lol:

Okay panel wipe, cooking petrol, Coleman and optimus fuel which yes will Flash fry a cow in 20 seconds on your brew up stove most definitely isn't designed for engine use.

I.e there's no upper cylinder lubricant in it (like you get in easy start). This probably in hindsight isn't too much of a problem in most saws because they're pre mix, but it'll burn out anything 4 stroke that's for sure! It runs hotter ( therefore it will shorten the life of air cooled engines ) and may be more prone to detonation than conventional 4 stroke pump fuel.

 

Best to leave it to the campers.

 

If you're after exotic petrol get your saw on some avgas with a 25:1 mix of Castrol R.

leaded is lovely. .......... mm mm mm. !
