Hi:
Happy New Year to all of you.......
I was wondering.......My 2001 Ford 250 came
with a computer,which is on top,right side of
the driver seat,one can read temp,how many gal
of fuel left and also the average miles per gal.
Does anybody know how accurate this is?Many thanks as usual for your replies.......araucano.

My 1998 Chevy Venture had one. I did the math and found the computer to be very accurate.

The computer mpg's on my 2001 F350 was usually off by 2-4 mpg. It would register 14-16 mpg when I really got 12-14 mpg.

Those overhead console computers are close. But if you are looking for MPG accuracy you have to do the math by hand.
Check out http://www.thedieselstop.com for more detail.

I have had two vehicels with the tripMPG computers and neither were dead on. With a fuel injected system, the fuel pump overpumps and excess fuel is returned to the tank. The computer makes a close approximation of the fuel that actually is passed through the injectors, but it is not dead on, so do the calc if want accurate info.

Great to have but when towing, but I never trust the range to empty because that last half of the gas gauge may be on roads that are very steep!

Which means that computer isn't going for gas, you are!
Almost found that out the hard way but lucky for us there was still enough gas in the tank below the <span class="ev_code_RED">red</span> mark of the dash gauge

Mike.
