Had to complain to my fellow V owners. Stopped by the gas station last night to fill up and was literally the only car in the parking lot. So I got out as usual and opened my own tank and took the cap off and hung out properly (I live in OR so cant pump on gas), so I take the precautiion to everything but pumping myself. I told the gas attendant who was in his 50s probably to fill it up with Premium. He said sure thing, swiped my card and said once again fill it up with premium sir? I said yes, thanks. I usually will hang around since it takes like 1 minutes to fill up our little tanks, then I replace the cap and close door my self. I had my 3 year old in the back seat though so I went back around and sat inside the car to keep him company while watching the pump so I could jump back out and take care of closing up myself.The pump had reached 15 gallons and the guy walks around and says he accidentaly put regular in and what should he do. I told him to stop the pump ASAP. he apologized over and over again. I asked to speak with his manager and of course no manager working. I wasnt sure what it was going to do my car so I did some quick googleing on my phone and the best I could find was to add some Octane boost. Half the stuff I read said it would help the other half said dont waster your time. The gas station was at a truck stop so I told them to comp me on the Octane boost and my gas. He said he could do the octane boost but couldnt the gas because it was already paid for by credit card. I added the octane boost myself and will be limping my car around until its empty. The station has lost a good customer now. So from now on will be watching like a hawk with fuel that start with even if you get a verbal confirmation.
