Has anyone ever used Coleman fuel in the gasoline engine? It has a low octene rating (50-60) range. I like to try it but don't want ending up damaging the engine.

Thanks

I know a Heli guy who uses it in a Zenoah G26,swears by it.
That is all I know

Coleman fuel is about 57 octane. Many emergency crews use it in jaws of life type emergency equipment pump engines, because it's basically truely pure gasoline (naptha, actually), and so doesn't go bad in storage like modern gasolines. They just need their engines to start RIGHT NOW, even though they've not been needed for 2 months. It works well in low performing, low compression utility engines. In higher compression engines, just like any low octane fuel, knocking and detonation can result. You can try it if you like, and it may work well for you. Be aware of how the engine's running, excessive head temps and knocking are signs that the octane is too low.

As far as I can tell, in our applications, the only real advantage is low odour.

The other thing that you would have to worry/wonder about is the ability to mix with two stoke oil - a very important consideration.

Especially of the engine seizes and you go looking for a warranty claim. [:@]

The trouble with comparing ourselves to 'Other' groups is that they have different applications and someone else is paying the bills. ie a racing team has no problem winding a new engine up to 20,000 RPM on 20% nitro - they replace the engine after each race. []

Good Luck!

2 stroke oil does mix with coleman fuel. Coleman fuel is the same stuff as the petroleum base gasoline is made with, but they add octane boosters and oxygenates along with other things to gasoline to make it burn "cleanly" in engines. Cleanly meaning with minimum unburnt hydrocarbon in the exhaust.

The only real problem with coleman for engines is it's low octane. Many places in scandanavia (so I've read) used to sell what amounts to naptha (benzin, white gasoline, enviro gasoline) at regular pumps for use in cars and especially outboard engines to reduce the nastier chemicals in regular gasoline from entering the environment due to spills, etc. Again, it was a low odour, low additive, low octane gasoline.

Your point on warranty is germaine, it likely fails to meet the minimum recommended octane number... And thus would void the warranty.

It does work great in sidevalve 4 strokes, tho! 5:1 compression, LOL

Lower power, more heat, much less smell.
With proper cooling no worries.

Run it at your own risk, then take your chances. It all depends on the engines compression ratio.

I've used it for several years in all of my Zenoah's (26's-62's) mixed 40:1 and it works fine. Before I did run them on it, I contacted Ralph Cunningham for his suggestions/comments and he said they would be fine for my kind of sport flying.............[8D]

I have used about 50 gallons of it in boat engines, modified, and I havent had any problems related to fuel ever! The biggest problem with it here of late is the cost!! But then again it does cost more to go first class ha!!

So I guess I don't quite see the point if it's lower on power. Is the only advantage that it doesn't smell? How can you not like the smell of 40:1..LOL.

Seems like to me if you had some coleman fuel or white gas on hand...it my work to use a small amout of octane booster if needed!!! What you think? Capt,n[)]

Just bought a new DA85 and in the manual it states using coleman will void warranty.
FWIW.

Our "Dawn Patrol Leader" (he likes to be at the field early enough to see the sunrise!) has used Coleman fuel for years in all his gas engines without any problems whatsoever. It has its own peculiar smell, however, which can bring on memories of camping, eating hot dogs, and roasting marshmallows.....so beware!

Be sure the mantels are properly attached before usingthe fuel-
