Go to State Line, just past Post Falls, Idaho. Near the Stateline speedway and strip club. There's a gas pump you can buy "Renegade" brand 110/114 octane for 6.25 a gallon. Just pay with credit/debit card. It's good fuel I used in Super Late Model stock car. You can get it by the barrel too, if you talkj to the gas station 1/2 block away, I think it's a Shell station.
