There are quite a few items that can lead to worse miles per gallon. You are correct that all sensors involvrd can be out of specifications and not store a code. Tires, wind, altitude and fuel itself all come into play. I saw a type of magnet that attaches to your fuel line. It is supposed to magnetically correct all the fuel molecules so they can travel through your combustion chamber with less resistance, supposedly keeping a more controlled rapid expansion of the flamre front as it moves your pistons down turning chemical power into useful mechanical motion. I forgot where I saw it. Keep your tires at their max pressure in winter, loose any weight your carrying you don't need(not your wife or husband though), and have your o2 system monitered. You could even go to the store here and buy some cheap testers to moniter all your systems. I can't believe how inexpensive the tools are today compared to 1985. Then a fuel pressure tester was 3 times as much. And it was much more difficult to use. I always try to drive with the cars inertia in mind. Starting off from a stopped car. This is where most of your gas is used. Just like Sam Snead said, "try to hold your golf club like your holdind a bird between it and your hands". Same with your gas pedal. It works. The cars mileage. Not my golf swing.
I think the fuel today is not only more expensive, but not as powerful. There is only a rating for quality against knocking or pinging as we called it. Who knows exactly how much cheaper its made.
Why not look at all your systems with a monitor, most scanners have this feature, but their the more expensive ones. Your o2 sensors which command fuel management and your air intake are the most important parts that can cause a drop in fuel economy. Soon Hydrogen. See ya, Joe
