Corrected entry: When Neal and Del are waiting for Owen, they discuss which credit cards they have. Neal says he has a Visa, gasoline card, and a Neiman Marcus card, whereas Del only has a card for a Big n' Tall shop. Neither of them mentions their respective Diner's Club cards, which they each just used the night before to pay for the motel.

Correction: Diners club was expanded to be used for other things besides restaurants in the 80's. It could be used for all travel purchases which is why Del was able to use it for a car rental. Neil using it as just a gas card was plausible. Since we never saw any other cards in his wallet when they arrived at the motel after the car fire, it could be assumed that's what he meant by "Gas card."
Correction: Typically, the Diners Club card could only be used at restaurants and hotels. Not for gasoline, retail goods or services. So, the DC card could not be used to 'charge our way home'.
Correction: Del's card was not a Diner's Club card. It was an Overnighter's Discount card.
The question still stands. Why didn't Del or Neil mention that they had those cards?
