Flying J fuel card

I have always been a J customer. But I have noticed that a lot of the smaller carriers have a 3rd party fuel card. They do not want you to use the J. Loves is ok and some have TA. Apparently the J stopped giving big fuel discounts to the small carriers. Lowes sucks. Small parking areas and not enough facilities. These days a 59 truck is next to useless. Filled to capacity by 2 pm.!
