Anyone with reliable information on the quality of Sams Club gas? I'm north of Chicago and they really jack up the price on premium at the normal top tier stations (BP, Mobil, etc) Some stations are $1 more than regular.
Ridiculous. The Sams Club prices are really tempting at about 50 cents cheaper per gallon but I'd like to know what I'm putting in my car. I know Costco is listed as top tier but I don't have one of those near me. My internet search on the topic came up inconclusive.
Should I avoid or not worry about it...
