I wholeheartedly agree. If you have access to ethanol-free gas, you have all you need. It's expensive, but worth it.
And if it is dispensed from the same pump as ethanol fuel, run the first gallon (or two) into your vehicle. Otherwise you have a blend of ethanol and ethanol free in your gas can.
I've seen old trucks pulled from a barn with 1/4 tank of old gas in them, after setting for years that start and run with a jump. Good luck with ethanol fuel that is 90 days old.
