yes stations with a separate hose for each grade (Kwik Trip) are nice. Then again a bit of ethanol in a regularly used fuel system can actually sop up any lurking water in the tank. When filling chainsaw cans I tend to run a gallon into the car then fill the 2stroke can.
It's a bummer getting some regular price gas when you're paying a buck a gallon extra for premium non ethanol.
Prolly a leap of faith that you actually get what you pay for by depending on some unseen pump blending mechanism/solenoid valves.
Quote from an ADV rider posting:
I contacted Shell Canada about this being concerned about the fuel for my 2-stroke equipment which states to use NON-ethanol fuel only.
The reply I got was:
Hello
On the use of a single hose to dispense multiple grades of fuel - Shell standards for these multiple grade single hose pumps are for a smaller diameter hose to reduce the amount of fuel left over from a previous dispense. The fuel grade change point is directly above the hose connection resulting in a residual volume of 0.56 liters for small diameter hose, or 0.78 liters if the pump happens to be equipped with a non-standard large diameter hose. While this amount will have only a very small effect on a typical car fill up, the effect is larger on 2 cycle equipment or a motorcycle tank with limited capacity.

I had contacted Shell because they had recently renovated the local station which lost the dedicated Premium pump in that reno. All the other gas stations here had already been converted to blender pumps. I flush the pump hose into the vehicle, then I make my 2-stroke mix.
