i live in the u.s. i'm not a motorhead by any means but ethanol laced fuel is poison to boat motors and other small engines such as lawn mowers, chain saws, generators and the like. my car ('93 corolla) went from 38 mpg to 31 mpg with the stuff- about 20% drop in fuel economy. it's terrible.
we can still get non-ethanol gas at select gas stations, but it's $ .25 more a gallon. worth it for the boat, etc.
and, the price of corn is so high people can't afford to raise their own pigs and cows anymore.
good luck!
