I agree, Headsmess, about people making this hobby waaaaay more expensive than it needs to be. The chinese run 30 wt motor oil mixed with low octane gas, and it works fine. Personally, I run the Wal-Mart generic mixed 32:1 with the cheapest gas I can find, and haven't had a single fuel issue. But, like Al says, if you don't ride much and let your fuel get old, a stabilizer is a must. All this fuss over high octane and miracle additives is just a way to blow your hard-earned money out the tailpipe.
