Ok, as noted above, I called for a CLI after 3 months instead of 4 and got shot down. So I waited until my 4th statement posted then spoke to an underwriter. Got denied! A letter arrived a week later. It said that I didn't have enough time with my current credit limit. Could that be because they gave me an auto- CLI after 2 months so I have to wait until 4 months after that? I've been using and paying the card down/off monthly. 

Happy to hear that a SAMs club will be going up near me and they will be selling gas.  Good use for the card!
