What’s the best card for fuel management?

I'm willing to switch from my dispatch company and run under my own authority. It's now 6+ months old (unless I find another reliable dispatch). And doing the same research. The company I'm with now has around 25 o/o and they use RTS Pro and their savings are really good (especially at some Pilot/FJ locations). Probably because they use RTS financial services. So I was thinking how and where can I get similar discounts. Preferably at Pilot/FJ (have my own espresso maker, so quality of the coffee doesn't bother me at all, unlike having a shower all over the States). Loves is just too expensive for the times we're in now.

P.s Also, I used to use TCS cards. They are easy to apply for and free, offer good discounts (40-70 c depending on the location) but work on a cash basis. Which should be ok if you're an o/o

 

Here is an example of TCS cash card saving, just fyi
