one would think i would pay attention to these sorts of things, but i don't.
i use a 5 gallon jug, and i add 2 gallons to this jug when i think it needs it. so i've not had an empty jug, or a known quantity in a long time..
come to think of it, that probably means there's some old gas in there. but the gasgas is the only bike that i have that i run 50:1.. i'm switching to 40:1 this year, so maybe i'll empty the jug finally.
