On either loyalty/credit or both cards, show me the market price of the fuel/gallon and the final cost/gallon (don't just show the savings total for each purchase). On the credit card statement adding all the gallons and savings, show me that I saved $x by using my card(s). This not only reinforces the savings I get from using my card(s) but it would help if there was no receipt (I would have the total cost and the price per gallon). This would also help with tracking mpg from another suggestion.
