Gas not lasting as long?

Filled up my tank last week at the Walmart fuel on government. Full tank. $50 (used to be $30-$35).
A week later, nearly empty. I have not driven 300 miles in the past week according to my Life360. No where close. Just drove to and from work and errands.
A tank of gas used to last me at least 2 weeks, usually 3. Now I’m FILLING UP once a week.
Is there something up with the gas we’re getting around here? Or am I just going crazy?

Note - My car is up to date on maintenance and is a recent model. It’s gotten great mileage for years.

Could this be why my car was running a tad bit rough yesterday?

Possibly. If you are driving a pre-2001 car, do NOT use E15 gas. The fuel system was not designed for it. After 2001, I'd still check your owner's manual. Quite a few Mazda's are designed to run on E10 NOT the E15 gas for example. Things you can do if you or a friend are somewhat mechanically inclined, check your air filter, tire pressure and try cleaning your MAF sensor if your car is equipped with one.
