The MPG thread.

This is one of the reasons why i got the digital speedo----for accuracy.  GPS would probably be even better.

i also fill at the very same station and if possible the very same pump and let it click itself off.

87 Chev 1/2 ton, V6 FI 3 speed standard, 3.08 gears.  I get 23 MPG just jigging around some highway, a lot of country driving around 80 KM/H, and some town driving.  Towing a 15 foot travel trailer at 80 KM/H I got 18 MPG.

Had a 87 F-150 with a NP435 4WD 3.08's and a 300 and could never get better than 13 MPG.  IH Scout 800 with a 304/automatic and 3.73's does about the same as the ford on the highway.

Wow that little v6 is really doing its job.  I had two '97-up f150 v6's that wouldn't pull down that good of mileage, kudos.

1991 R3500 Crew Cab, 350 TBI/4L80E, stock gearing (4.10), stock tire size.  13/17mpg
1987 R10 Regular Cab, 305 TBI/700R4, stock gearing (2.76), stock tire size.  18/22mpg

So I have been doing a lot of short distance driving and apparently the '85 does not like that.  Without some higher speed cruising thrown in, the mileage goes way down.  It must be the 2.73's.

Dang, something must be wrong with my truck lol.  I wish I got 18 mpg, instead of 14. Four more MPG's would help me out a lot in the wallet. And im not a leadfoot or anything like that. I drive like a granny, cause I can't afford to fix right now it if it breaks.

I stuck some new plugs in to replace the old rusty ac's and replaced a lot of 25yr old vacuum lines along with an oil change, air filter, and a pair of new front tires.  I think I have bumped my mileage to 17-18mpg hwy.  The vacuum leaks helped a ton, but I have one left.  The vacuum advance is leaking so I have unhooked it for now, so hopefully with a new one, it will do much better.
