@icare4america I asked several others. I did think either my car is just old and inefficient, or maybe just from filling less than before, or because it's a bigger financial hit I notice it more, but it's actually pretty ridiculous, and every single person I've asked tells me the same. Old cars, new cars, bigger cars, tiny cars. Even being conservative with the miles driven, The gauge just drains.

They're definitely doing something. But I'm not sure which of the "they" in the chain it would be.
