got 15 or 20 gallons sitting around in 5gal gas jugs the past 6 months up off the cement on the shelf, who has some knowledge with older alky not in sealed drum, some of the properties of the fuel may suffer I imagine ?

 

That depends on how good your jug is sealed up. It will also depend on how much humidity you have around the jug. If it wasn't sealed up air tight it will attract water like a mother. If it was sealed up air tight you will be fine.

 

he is right,
most likly i wouldnt use it.
it will still run ok but you wont get max hp.

 

Don't have aclue about the Alky, but I know the Gal jugs of white liquor we get doesn't last long at all, lol sorry I had to post that. =]
