I try to use my corresponding branded card at gas locations, though lately I've been going with my Verizon VISA which pays 4% back on gas.
What's frustrating is the wildly inconsistent implementation of gas credit card procedures by brands that all use Synchrony.
My Chevron card is the best. I instantly get a text when a purchase is denied for questionable usage, and it instantly gets opened back up when I respond.
The Phillips 66 card can be infuriating. It gets denied at the pump a lot (so I use the Verizon card, also Synchrony, has never been denied for anything) but I can use the card for the store purchase.
Have synthesizers, will travel...
