This is a puzzler of a different sort for me.
I recently had an alignment job done on my 2004 Toyota Prius, as well as a replacement of all 4 tires. Since then, I am consistently experiencing 2-3 fewer MPG on my gas mileage readout, despite employing the same route to work and driving habits. I am on my third tank, now, since the work was done and the mileage has been consistently 50-52 MPG, where I normally am able to get 53-55 in this type of weather.
Does anyone have any insight as to why this might be happening?
