I'd rather run out of gas than support Citgo. Can't remember the last time I got gas there. :Bye:
I had two different experiences at Citgo - both times, my little '81 Accord backfired. That thing ran on whatever I put in the tank, but not Citgo. So I've never gotten gas there again. That was back in '91, I think.
Sam's Club I've never had a problem with. I prefer Shell, but sometimes Sam's is more convenient. My uncle absolutely swore by Amoco (now BP) Ultimate, but the Jeep doesn't need the octane.
