Warning: Bad to bump start and skip gears

[philmcneal]

since this threada bout the fear of bump starting i'll add to other people's remarks

Even if your tires do not blow up on you, they will wear in the middle in no time. In any size, at any cost, it takes more to replace tires then what you save on gas.
Your engine works outside of the designed temperature envelope, which means fouling everything- from spark plugs to your catalytic converter. Plus, your oil probably has never get to operating temperature (it takes much more time for the oil to get warm then the coolant). You do not ever burn the moisture and fuel contamination out of your oil. That means the sludging possibility is eminent, even with synthetic oil.
Re-starting the engine as often as you do increases the oil contamination by the fuel and removes vital lubrication layer from the cylinder walls.
Your exhaust will rust out very fast too because the water condensation there does not ever burn off.
It is not quite safe to switch the automatic transmission from D to N while driving. Depending on conditions you might as well switch into R with all the consequences.
As was mentioned before, you lose ABS, EBD, power steering and get a strong possibility of the steering wheel lock-up.
I have the ScanGauge as well. As much as I like it for everything else, it is not as accurate in measuring the fuel consumption as "at-the-pump" method. I log both every fill-up, and the SG readings are usually off by more then 10%, no matter what engine size you set in SG.
To me, some of your tips totally make sense, although many are just not helpful, and some are quite dangerous.

hmmmmmmmmm svoboy i didn't know axels were that cheap to begin with haha.
