Your gas gauge might be giving a false reading. You should actually measure the fuel you are using at the gas pump. Also, the recent cold spell will make mpg drop quickly. Are you using remote start a lot more now? Have the fuel pressure tested. Too high will increase consumption. In some areas they are dumping a lot of alcohol in our gasoline, which has much less energy than "real" gasoline. Just a few ideas.

Toyota 1UZFE engine. Confirm the timing is not off (retarded) by one tooth! It will run sluggish and burn more fuel! Check the engine vacuum 19-21
