Costco or Sam's Club Gas?

[1olddude]

Here in Utah Costco and SAMs are always .15 to .20 cheaper than anywhere else. It's the same gas, they just have tremendous buying power and sell such large quantities that they don't need much of a margin. I have used it in all my cars for years with no problems whatsoever. I take the savings and drive a few more miles in the Box. Now if I can just get that transmission mount installed I will go filler-up and put the pedal to the metal.
