Best gas station rewards programs?

I recently got a new job where I'm given a corporate gas card. I drive a thirsty boi so I'm filling it up a lot. I'd accumulate a ton of free fuel points but unfortunately most of them only give discounts for gas, so I'd be saving the company pennies and it would go unnoticed (they have a fleet of 100+ vehicles). Anybody have experience with rewards programs that let you spend points on things other than gas?

Edit: located in Atlanta, GA area. Only fuel up regionally.
