I can understand the whole drive slower to get better mileage, but driving 68
or slower on any major hwy in AZ will cause a major back up.
I've driven past the 65 miles per hour crowd and there's always a somewhat dangerous
dynamic when everyone is going around one car in the right lane..
The mileage game seems like a financial magic trick as well.
Spend 100's of dollars and countless hours working while driving slow to save
a few bucks a tank.
Not sure it will ever even out especially in a year when many of the tune up,
foam this, ad magic elixer mods will need to be done again.
Again..........I'm referring to a well driven vehicle , not a garaged show vehicle.
I drive alot here in AZ and I don't think I could drive with every car looking over at me as if I'm breaking down
or as if I should have my hazards on.
My 99 runner is stock with most air related mods reversed, a new tune up, auto , clean sensor etc. 17-18.5 will have to do.
I could not imagine the 20's.............or driving 65 Kenny S>
