Costco versus Chevron/Shell or any Top Tier gas?
I used to put Mobil 1/Chevron since it was close to my previous jobs But with Costco less than 3miles away from my house, its where i've been going. Just avoid 7/11, East Coast, Liberty unless you want to take the risk. When gas prices were higher earlier this year, it was $.40/gallon more than Costco. $7.20 more at 18gallons
