Improvements that actually work are listed here: 68 vehicle mods for better fuel economy ...

The fun part with this is that every platform is different with its own unique aerodynamic, weight, powertrain and other issues. Identical mods will have different results on different cars. Removing the side mirrors will helpful, but will they be as helpful as wheel skirts?

few of these devices seem to have been objectively tested so we really don't know whether they work or not. i'm willing to outlay some money in the interests of science.
ROI is another way of saying "effectiveness." Every production car will benefit from some basic mods the moment you make them, while reinventing the wheel for combustion in your spare time may help someday- in the car that you've left otherwise as inefficient as it was the day it left the factory. Until you hone your own driving skills to be as effective as possible none of your data will be worth a damn. None of it. The driver is the biggest variable in FE and you can't objectively test anything until you can be an objective tester. Time spent working on technique isn't wasted- time spent driving without working on technique is.

There's no sense wishing for better mileage if you won't work on yourself.
There's no sense modifying your car if you won't modify the way you use it.
There's no sense reinventing combustion if you're going to ignore bigger inefficiencies.

A journey of a thousand li starts with a single step. Start with that one.
