On that note, if it sat for a long time, then the gas probably went skunky too. When I store my truck over the winter, the last few weeks before I store it, I drive it a LOT and fill it to the top with Shell 91 octane, which in my area has NO ethanol in it. Ethanol is great for burning a little cleaner, or stretching out our planet's fuel supply, but it will go skunky if you let it sit. (try it - get a couple of Jerry cans and fill one with 15% ethanol 85 octane, and another with 91 octane 0% ethanol - let them sit for 6 months, and then take a sniff... the 85 octane smells bad.)
Learned this trick from guys with outboard boat motors who only use a little bit of gas on their sailboats... some of their gas is YEARS old and as long as it has no ethanol, then it stays good. No idea what the chemistry is behind this, but hey - it seems to work.
