97 C230 running rough and using gas

This is a former Starmark car with 102k that has had a lot of work due to me whining about every last thing at the dealer. Past 4 tanks or so, various stations, all 93 octane, motor buzzes and vibrates, and my mileage is notably down.

Winter fuel?

I use techron every 5k, the car has had the entire plug/wire/resistor setup replaced 15-20k ago, oil is clean, motor mounts just passed indie inspection.
