Hi all, new member first post. Does anyone run 100 octane/ aviation fuel in an echo 770? After having carb issues with one of my echo 770 (after one year of use) the service tech stressed the importance of ethanol free fuel. I have owned boats for 25 years and know all too well the problems with ethanol. The only place around here that sells it is a nearby airport, but its 100ish octane. Will this harm my equipment? The airline fuel is $5.00/ gallon, vs $20/gallon for the metal can mix at home depot. My plan is to use the aviation fuel during the spring-summer. I use my blowers only for 10ish minutes per week during the mowing season. I could probably get thru the season on 5 gallons of fuel. During the late fall leaf blowing season I use them almost every day, probably burning 20 gallons+ per week (200 gallons per season). Here my plan would be use standard gas station fuel for the 6-8 weeks of heavy/ frequent usage, treating said fuel with a bit of seafoam and stabilizer if necessary. Thoughts? Thanks!
