$5.49 for regular in Santa Clarita, CA. Had to fill the DD (Prius). My Tundra stays in the garage except when I'm hunting/fishing/camping. Typically, for hunting, on my way home, I'll fill my truck back up at Costco. But for the prius, which takes so little fuel to fill up, I just hit the Mobil near me. Lot more than Costco, but for 6-7 gallons of gas, not worth driving 20 mins away to save a five bucks. Plus, since I work from home 90 percent of the time, I hardly use either vehicle nowadays. That's probably the main reason gas prices haven't significantly impacted me.
