credit card travel reward credit cards vs comdata card

RTS Pro application to look where to fuel and fuel price. Different truckstops have different discount. Application use to be not bad, slow but working. Then RTS decide to add all this crap factoring, BOL sending in PDF. App says need update and doesn't work and wont update. Read review.
Anyway RTS network is narrow, in some states only one or two participating fuel stations.

 

Plus RTS discount is so small sometime out of network fuel will cover discount and out of network purchase fee.
RTS recently increased in network fuel purchase fee, if you running 80000 load with 1/4 fuel in tank you have to fuel every 200 - 300 miles and every fuel stop they charge you.

 

My Comdata discount at sapp brothers in Omaha is .80 less than the pump price. Should I use my credit card or Comdata card?

 

Rewards or cash back?

What does the rewards offer?

 

Comdata for me is always .45cpg off or more

 

I used TCS for a few months, I think they're ripping you off. Their statements are confusing as #$%, which lead me to think they're fudging the numbers. After all, dumb truckers aren't good at math, right? I heard someone else mention that when you look on the app, it shows you'll get .50 cents off per gallon at some TA, so they fuel up. Later when they get the statement they saw it's only .10-.15 cents off. I'm sure NASTC is legit, and Comdata as well, but a lot of these fuel card companies are sketchy as heck
