All good points to take into consideration. Don't waste your money on high octane fuel; it will loose it's octane as it sits (race gas looses a good portion of it's octane in just two weeks after the barrel is opened).

I prefer Sea Foam to Stabil, for what it's worth; but definately add to the fuel so it doesn't varnish. Your tires probably won't be much good, so plan to just replace them upon return.
