Welcome to the Forums!!!! Have you started doing anything different?

 

Welcome to the forums. Before you atribute your change of mileage to the engine/transmission, etc. check the usual stuff like: tire air pressure, use of a/c, have you increased your stop and go driving mode, are your idling your car too much, stuck in traffic, etc.
