Regarding Oregon. Google ''why can't I pump my own gas in Oregon''
Interesting reading. Since 1951 or so.
There have been a couple times where lawmakers have created a bill to do away with it. But it never gains enough traction.
Regarding Diesel in Oregon. Most places I've been to don't mind you pumping your own diesel and will actually ask if you've ''got it?'' if you start the process yourself.
Actually when it's raining 7 months a year it is nice to just sit in the truck:)
