Both pumps were replaced recently, as well as the main filter and strainer.
Tires are just regular street tires.
The alignment is checked twice a year and adjusted if necessary.
I run 93 octane fuel with a little of octane boost on each tank.
All suspension bushings have been replaced.
Shocks are recent.
Need to replace the air filter.

That's all that I can think of as far as what may change my fuel economy.
