Hi, does anyone know how long fuel can be sat for unused before it looses its combustibility?

yeh,after two year definately. something that suprised me which i recently heard is that petrol is general stale after just 6 weeks if sat still. how true that is i do not know but quite a reliable source.

Especially worse with super unleaded leads to melted pistons etc On 5th Sep, 2011 Vegard said:

i have 2 x 5 liter cans in my garage that i filled with optimax about 18 months ago and recently i have been wondering if it would be worth using it before i cant no more.. might not be worth the risk then??

Most old style low compression engines are fine on older fuel, but not 2 years old !!On my competition bikes if the fuel is even 7 days old they can be a bitch to start, so I drain the fuel after every use, put in fresh and they go straight away.I know of older A series that have started on 10 year old fuel, but doesnt it stink ?. |

For a normal (read low spec, type) car I'd be happy to stick it in mixed 50:50 with some new fuel, even if it was 2 years old.

I heard oldish fuel wasnt as much of an issue in 2-strokes, think thats why our petrol mower fires up after months of not being used, dunno how true that is though. |

Having said what I said above, the hilclimber started first press of the button on fuel that's sat in the tank since October 2008.

I would say that the way the fuel is stored is also a factor. Because it absorbs water, well atleast the racing juice that we get here does and has caused trouble for me in the past. "So wat we gonna do tonight Brain?"

Looks like it was the old juice.. drained out 17litres and put a fresh 5litres on BP ultimate, and after a bit of fiddling it fired up :) :) :)
