I've finally found the secret to increase mpg

I saw an increase in economy from 5.4 - 5.7 down to 4.8 - 5.1 L/100km. Give that some thought, just focus on keeping your consumption on the highway below 5.0 and don't worry as much about the speed.

Yes, I second that. Keep throttle SOLID without bouncing the pedal. If you have a ScanGauge you can program it with a "gas pedal pressure" gauge that will help you control your right foot. When you see the read-out you'll be amazed how much most people bounce the throttle without even realizing it, and Cruise Control is practically a "random throttle generator". Not good for MPG.

Back in the good old days, some vehicles had 'hand throttles' that held the accelerator; an early form of cruise control.

... 45 Minutes IF you are driving Over 400 Miles Per Trip. Yes, I did the math.

Most people will Think that they are Saving time by driving faster... I have found out that 1 or 2 Stoplights WILL take out All the time that you save by driving faster. Yes, this HAS been tested by three vehicles at the same time. the First vehicle had a speed of 70, The second had a speed between 63 and 68, the Third was mine that I set Cruise control at 55. I caught up with the Second vehicle at the First stoplight, and the First at the Third stoplight... The total drive distance for this test was 58.2 miles.

Oh, and As for anyone that asks..."What kind of Miles per Tank will driving 55 instad of 65 do?" That test I have also done in a rather fun manner. Both were done in the Same weather conditions, and over the same driving area. Driving 55, I got 630 Miles before the car gave the traditional Triangle of Death! Driving at 65, I only 470 Miles before the same triangle. This would be obvious for me to say that YES, I filled the tank to the same 11.85 Gallons both times(this is where you can actually SEE the fuel in the inlet).
