E10 in the original tank has to be used up or if months old, drained. I'm senior and lazy. I may forget how old the E10 gas is, or forget to drain it or don't want the hassle to catch and recycle the old gasoline. Non-ethanol is nearby in my area and is used regularly. Farmers and anyone who has older equipment swear by it.
