Fuel remaining in the gas pump hose

I've always wondered when getting gas, if the last guy getting gas got 87 octane, how much (if any) of the 87 octane is still in the hose when I start pumping the 91? I searched the forum but could not find the answer - anyone know??:confused:

not enough to matter. IMO, but to be safe just carry a 1/2 gallon jug with you to purge the hose j/k :roll:

I don't have the answer.. but I figure a 1/2 gal. Its only flushing that hose and the little bit of plumbing in the pump unit down by your feet. I don't work in the industry at this point. My involvement ends at the truck rack where the semi fills up.

Don't worry about it! One of my buddies who was driving a gas tanker said so many stations mix fuel anyway. Its a violation of the rules but the almighty $$$$ rules and wins. He was telling me last year about the winter mix (this is for northern states) and how it was on sale at the refinery or where ever they load up at. This was at the end of the winter months and the tankers were backed up for hours and the station owners didn't care about what was going where they just wanted it. I know he delivered to a lot of privately owned stations so I don't know about the big mega-stations of today that are gas stations/restaurants/donut shops and a multitude of other things, lol, but I will ask him!
