E-15 Gas
The EPA is NOW requiring that all customers of gas stations that pump both E-10 and E-15 through the same hose purchase a minimum of 4 gallons of E10 to dilute any residual gas in the hose and minimize the possibility of engine damage for motors that aren't able to use E-15.
Right now, unless some detail is provided regarding warranties and compatability, etc..the only thing I can suggest is that anyone who sees this sticker on a pump find another gas station.

As for the EPA..
What Vehicles and Engines May Not Use E15?
•All motorcycles
•All vehicles with heavy-duty engines, such as school buses, transit buses, and delivery trucks
•All off-road vehicles, such as boats and snowmobiles
•All engines in off-road equipment, such as lawnmowers and chain saws
•All MY2000 and older cars, light-duty trucks, and medium-duty passenger vehicles (SUVs)
Note the "prohibited by federal law" line on the warning sticker..
