Here's some recent info:

-Replaced oil filter gasket
-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?
I'm in the same boat as you I'm averaging 10mpg. everytime I take the car to the dealer for that . They keep telling me the engine is running fine there's no code in the dme . My car Is stock
