Engine efficiency depends on rpm (among other things) and slower isn't always better. More wisdom from the Honey Bear.
On a summertime cross country trip from Oregon to Ohio, I restricted MAX's radiator inlet air a little at a time, demonstrating that very little inlet area (28 square inches) provides sufficient air for cooling.

We're looking at a handful of low cost improvements, and since MAX is undergoing repairs at the moment, this is a good time to make them.
Hybrid cars save fuel by shutting the engine off at idle (among other things). Does MAX burn enough fuel at idle to be worth the effort? Our honey bear can tell us.
Technology marches on. It comes at a price, but a FloScan fuel consumption and mileage meter could give me instant feedback on MAX's fuel efficiency.
MAX got a new set of high efficiency Goodyear tires, and a second set of wheels so we can do comparison testing. Will the difference be detectable to our low budget testing technology?
