I've been using 93 octane with stihl oil for years in all my 2 stroke and 4 mix equipment and the only problem I had was the problem with the New Stihl gas caps recall and when I replaced the caps they were all still in working order and I infact carry the ones I replaced for spares. You say the Etanol crap reeks havoc on small engine if so it's news to me because I've never had a problem running gas with 10% ethanol in my hand held stuff or mowers. All the manufacturers say it's fine to run. Thing is you say you buy 5 gallons at a time and use STA-BIL fuel stabilizer 2 ounces to 5 gallon of fuel and its good for 12 months. I buy 25 gallons of 93 a week for as little as $2.79 a gallon, if you had to do that at $6.00 a gallon your tune would change in a hurry.
I can see why you don't have trouble your in Florida. I'am in Michigan you don't have the Winters that we do up here. Your equipment is being used most likely every day right or wrong ??. Do you store your equipment 4-5 months out of the year ??. I think not. People that don't know about ethanol and it's effects don't drain the fuel systems on their small engines before storage and the result is costly repairs. Ethanol is crap here in Michigan. I've been a Mechanic for 40+ years and I have seen first hand what the stuff does to carb's, plastic, rubber fuel lines, seals and metal fuel tanks. White rust corrosion in carb's, break down of plastic, once pliable rubber fuel lines now brittle just break in half and fuel tanks full of rust from phase separation. not to mention fiberglass fuel tanks on boats breaking down due to the effects. So what do you think. Would you like to live in Michigan and run a Lawn Service. :wink:
The Video is a example. Don't know what State he's in.
