Most modern pumps in the US have one hose and buttons to select the grade. You’ll get a bit of the previous customer’s selection from what was left over in the line, but it’s not a huge difference if you’re getting 10 gallons. It can be a bigger deal for something with a small tank, like a motorcycle.
Diesel still gets its own hose, as putting diesel into a gas car or vice versa can be very bad.
I have selected premium several times and then the tank stopped filling 30¢ early and my receipt said regular despite selecting premium when filling up my moped. I think the machines try to account for the gas type difference sometimes or maybe the pumps I was using were a bit dodgy.
