Gas Milage Tips And Mods?

[31_bandits]

while its true that anybody who is going to be paranoid about mileage, yet bought a hummer, is fit for the looney bin...

the same could be said about anybody who wanted to go really fast, yet bought a hummer. so the same basic logic could be applied to superchargers and all of those.

nothing wrong with wanting better mileage or better 0-60 times, perhaps?

I noticed last night on my way by a road-side radar sign that my speedo said ~40, but the radar sign said 38. Now i realize this isn't proof-positive that my speedo is off, but...

if my speedo read high, perhaps my # of miles would run up too quickly, and the mileage reported by the 'puter would be skewed upward?

similarly, if some of you are running larger tire, perhaps your speedo reads low & your mileage gets reported as worse than it is?

is there something right or wrong with that thinking? I should calibrate it with mile markers & a roadside gas pump, perhaps.
