Hate to say it, but the "gas" mistake actually happened to me a few years back. I'm use to the diesel pumps in San Diego having green nozzles. I was driving through LA, and my mind must've been on auto as I was fueling up. I just picked up a green nozzle, and started filling up. It wasn't until I finished that I realized that the diesel nozzles up there are yellow! Luckily I found a garage nearby that allowed me to dump all the fuel - out the drain plug. I'm paranoid now, and always look for the pump that "says" DIESEL.
BTW, my 110 use to belong to Chris. Can't Thank You enough for selling it to me.
