Or, underinflate your tires by 5psi, then inflate them fully and there will be a distinct improvement.
This year the EPA changed the way they measure mpg to more closely reflect real life conditions. Previously almost no one got the mpg listed by the EPA.
We typically beat the EPA listing by a couple of mpg. I have heard of people termed 'hypermilers' who tend to get quite a bit over the listed mpg, however some of what they do to get there is not recommended by safety eperts  |
Those are good examples of variables that impact mpg. I would add in environment also. Driving with A/C on lowers mpg as does driving with the windows down at highway/freeway speeds (messes with the aerodynamics).
One trip to Duluth the variation in MPG was impacted greatly because the trip up we were fighting a very strong north wind. In my mind I have loss of 5 mpg on the trip north and normal mileage on the trip south (it was a LONG time ago). But the winds had died down alot on the trip south. We had headed north to watch a storm blow in.

It would be interesting to see if some of the variation in your mileage was impacted by weather conditions.
