When I mixed my own fuel, I got gallon jugs from the hardware stores. Now they are about $10.95 CDN. That way I knew it was fresh. I only ran .15s so I didn't really need much. It is used as a paint thinner for shellac I think, for the most part. Gas line antifreeze for the DIY guys. Maybe I should check around for a cheaper source now that glow fuel is more rare and costly. It is possible to use no nitro. The oil is a pretty penny too. It would be nice if a cheap hardware store synthetic would mix with the methanol and be usable at maybe 10% or so.
