Next time you take the bus out, lower your cruise speed to 60mph-you'll probably get 1-1.5mpg better.  In the trucking industry, we figure for every mph between 55-65 you loose .1mpg.  And between 65-75 you loose .15 mpg for every mph.  So the difference between cruising between 55 and 75 can be 2.5mpg!  A big deal when you're running a truck at 120,000 miles a year, but with us running around 5,000 miles a year? Yous makes yous choices.  Good Luck, TomC

How do you know how full the tank was before you started?

How different was the level when you finished, again, using what method to make your decisions?

There is easily 20 gallons difference between pump shut offs. A gallon of fuel is 231 cubic inches. Measure the top portion of your tank and be amazed at how skinny a gallon of fuel is.

Throws the calculations right out the window if you don't fill all the way to the lip at a level pump,before and after.

In theory, under that terrain, your fuel use is capped by the power that the 6V71 can make. An 8V71 would burn more, running the hills slightly faster. You should have fuel economy that would make most of us jealous in those conditions.

I'm VERY suspicious for fuel leaks.

Lots of fun!

happy coaching!

I had a 79 MCI5C  6V71 with auto.  I never checked my fuel mileage cause I really did not want to know!! I always had the pedal to the floor. Drive it like you stole it I was told, top speed uphill, downhill and on the flats was 69MPH till I got GPS, then I found out top speed was really 71 MPH.

Again I never checked my mileage but I know it was no where near 4 MPG, that's horrible even I would have noticed that!! I also towed a 98 Ford Windstar, that was usually full, it was as much a mobile shed as a toad!!

No matter where you go taking the same route if it's uphill one way its down hill the other, seems like it should be a wash?? Or am I missing something??  I know when I was a kid, school was uphill both ways!  6 feet of snow oh never mind.     HTH   JIm
