In a recent thread we had comments about fuel mileage, SUV's etc. I
did some research using my full sized car and the instant read mpg on
the computer that it has. I took readings on the same places,
seemingly very level. Keep in mind the gauge read whole numbers so
decimals are not show but may be rounded.

Using cruise control to keep the human element out, I drove at 70
mph, 65 mph, 60 mph. There was no shown difference between 65 and
70. When I made the run again at 60, is showed a 3 mpg increase.

I drive about 12,000 mile a year on highway (total is about twice
that). Saving the 3 mpg saves a total of 52 gallons of gas. At
today's price of $3, my savings per year is $156.

Now, driving at 70 mph, I will spend 171 hours at the wheel. Driving
that same distance at 60 mph, I'll be spending 200 hours for the same
trips. So, to save $156 I have to give up 29 hours of my free time. The
actual mpg will vary on different cars, but that is what I was
able to do with a Buick LeSabre. I also don't notice any difference
with the AC on or off so I go for comfort. YM WILL V

Dripping 5mph to 55 mph would likely save more than the 5 mph between 60
& 65.
