Re[2]: MPG survey

I agree with Jim, the 40MPG is awfully high for a '70s vehicle...are the 
wheels truly stock?  Smaller wheels will give better results.

I use the speedometer check sections on Interstate 5 to check my 
speedo/odometer.  They are 5 miles in length and at every mile there's a 
sign (Mile 1, Mile 2, etc.).  When I travel 5 miles my odometer shows 5.25. 
 So I have to remove these extra miles when I compute my gas mileage.  I 
divide my odometer mileage by 5 and multiply the result by .25 then 
subtract this result from my odometer mileage to get my true odometer 
mileage (see why I wanna programmable speedo?).  If I didn't do this I 
would be getting very good results!  For those who are using bigger 
diameter wheels/tires you should do the same thing but you will find that 
your (actual) mileage will become better instead of worse.  My front wheel 
height is 23.375 inches.

Another highway point of interest for those who gotta know their car's 
Along I-5 are weigh stations (we have a lot of loggers in this state) for 
the big rigs.  Most of them are small and at night are hardly used.  Just 
drive up onto the pad and look at the nearest pole in front and to the 
right of you and you'll see a 5 digit fluorescent display.  This will show 
the weight of the vehicle.  My baby, with spare tire and fairly full tank 
of gas weights in at 2400 lbs.  Just remember to remove your weight from 
the display or get out of the car and off the pad so your weight won't be 
included.  You may need to scoot a little forward or backward on the pad 
until the display shows the biggest number -- that's your vehicle weight.

Next week I'll discuss how to prepare a hot meal while driving those long 
highways using just your engine and a Swiss-army knife...  ;p

Sorry, I don't believe it!  This is either his/her imagination or the best
downhill ten miles he/she ever drove.
