I always run non-ethanol 93 octane gas in my 2017 TriGlide. If the guy that used the pump before me pumped ethanol 87 octane and then I pull up and select non ethanol 93 octane am I pumping ethanol 87 octane that is in the hose until the 93 octane replaces it? I have been told there is no such thing as a dumb question but this may be one.
