The more ethanol you add, the more likely separation will occur,especially if the "gas" is not used within 80-100 days.Best case scenario ethanol gas has a shelf life of 100 days.This is why it is recommended that the fuel be used in 80-100 days or drained out and fresh fuel added.The longer it sits,the more moisture it draws, which causes the sludgy residue,hard starting,and poor performance. The ethanol drops to the bottom of the tank and absorbs moisture which effectively lowers the octane rating 2-4+ points....so your 87 octane fuel now becomes 83-85 octane, which in an engine without knock sensors and variably adjustable timing will cause severe engine damage ie. holed pistons,excessive pinging,sticking valves or worse.
