Gas
Sinclair, recognizable by its green Dinoco-style dinosaur logo, is a longtime western US fuel brand with stations across many states. Pay at the pump and the charge codes as a gas or fuel purchase, which is exactly what a card with a gas bonus rewards. Inside convenience-store buys may code separately as retail, so use a fuel-focused card at the pump and a flat-rate card for snacks.
