burning more fuel than usual?

I just noticed my cars been burning alot of fuel these past two weeks. The dashboard says im doing about 14mpg.

Here's some recent info:
-In december, I had codes for all four O2 sensors. Mechanic had a hard time figuring out the cause but turns out to be PCV short which I replaced.
-Replaced oil filter gasket
-Oil change
-Vehicle inspection
-Added power steering fluid
-Added window washer fluid
-Added engine coolant (I decided to just add PEAK coolant)

Car was running fine for a few weeks until just now I noticed I started burning more fuel. I just ordered a new air filter hoping that it might help.

Any ideas on cause? Maybe related to the repairs or coolant I added?
