G38 On Coleman Fuel

       Remove this ad - become a site supporter!
Here is a G38 running on Coleman Camp Fuel with a 32 to 1 oil mix using Amsoil Saber Professional. Engine is throwing an 18X8 prop. Moving the throttle around a bit to see if it hesitates or wants to stall, seems nice with very good response. Think I will pat it on the bum and call it done. I am tuning this for a friend who cannot stand the smell of gasoline. He's willing to spend the camp fuel prices who am I to question it.

Re: G38 On Coleman Fuel

Coleman fuel is what use to be called "white gas", it is gasoline with no additives in it. Back in the late 1940's it was the preferred fuel for model gas engines.

Re: G38 On Coleman Fuel

I too, hate the smell of gasoline. I use nothing but 100LL AVGAS in my gas models, riding mower, lawn mower, weed trimmer, etc.
At $1.50/L it's not too expensive, given the amount used. A 20L Jerry can costs $30 to fill. For model engines and weed trimmer, I use Shell 2cycle oil(NOT synthetic), mixed 30:1. I've been running this mix for over 20 years with no issues, no smell, no starting problems, no bad/old gas in the spring, and no spark plug issues. I've yet to hear anyone complain about the sweet smell of AVGAS, either. I've also never had a problem getting it from airports, most fuel suppliers are quite happy to sell it to you as long as it's not going in a car or truck(for tax/liability reasons). Try it, I'm sure you'll like it.
P.S. I've been using 20X8 props on my Zenoah G-38's after break-in. Lots of pull, still great throttle response.

Re: G38 On Coleman Fuel

I don't know either but all things considered. An 8 oz tank ran for quite a while where a nitro motor swinging an 18X8 would have emptied the tank pretty quick. Also no smell. Since the Coleman fuel is about the same as a gallon of nitro one could look at it this way. Not as cheap as car gas but still quite a bit cheaper than glo fuel. If the smell of gas bothers you then its an alternative to going back to large thirsty glo motors. Thank goodness I don't have to resort to that with all my gas motors surly goodness and mercy it would put a pinch on my wallet.

Re: G38 On Coleman Fuel

I never have an issue with gas smell, I drain the tank, plug the lines and stick earplugs into the exhaust outlets. Seems to do the trick as the lady never complains.

Re: G38 On Coleman Fuel

It's really cool Dennis but white gas definately has a smell to it. Not quite as strong as gasoline but still a fairly strong odor.
I mix it 3/1 with 70wt oil for my old ignition engines. I love the smell but then again I like the smell of gas, glow fuel and diesel.
