I put fuel in my pit bike and it's been sitting for a few months, now the fuel is orange. Is this considered good? It was clear yellow before I put it in.
It was freshly pumped from the servo the day I put it in & a few months later, it is dark orange.
Orange fuel? what made it orange? water phase separation, rust or maybe it was aircraft fuel with lead in it? 2 stroke premix? Stihl dealer have a yellow/orange colored Stabil meant for ethanol mixes that darken with couple months age- still good for up to 6-8 months. Sour smell is better indicator, low flash point another. Lots of old chainsaw gas just put into light trucks after winter setting, outboard motor gas the same use.
But why is it orange?
Because color change is one thing that happens when fuel gets old and breaks down. It'll smell a bit different, too.
It may clog up your carburetor. Best to drain it and refill with fresh fuel.
its old you wouldn't use it if you were racing it doubt it'll hurt the pit bike but since you ask old fuel is considered shiit
J E T H R O has it right. The interior of your fuel tank is corroding.
IT'S ORANGE BECAUSE IT'S BAD! I won't go into the science….
The orange is rust.
And that is what ethanol does, I would not put it in my bike.
