Re: MPG poll
This summer on my trip back from Washington to Wisconsin, I got anywhere from 15.5 to 18.8 MPG with the 250, three on the tree and a 3.73 rear, all stock setup, the only thing i did before leaving was change the plugs, coil, fluids, and advanced the timing. oh yeah and ran premium fuel and avoided that ethanol crap at all costs.

Re: MPG poll
Last tank I checked was mix of city and highway and I got 20.5mpg. Straight highway I have got 26.2mpg. Not too bad for rolling on 35" super swampers (4.10 gears). I am glad I did not go with the 572 motor when I was thinking about doing the engine swap.

Re: MPG poll
Estimated 10 mpg with 4.10 gears, 3 speed manual, 250 I6. 1/2 ton stepside. It's been 20 years since I've driven her but that's what I recall.
Once she's running again I'll be doing average mileage calculations after each fillup as I do this with my car as part of the fillup routine. |

Re: MPG poll
Yup. Just thought it could be relevant again with more overdrive swaps having been performed in the subsequent years and with fuel prices creeping back up. We all drive 50+ year old trucks. What's wrong with a 16 year old thread?

Re: MPG poll
I think old threads are fair game.
So, you got a t5. What motor, rear gears? What’s your mileage like? |

Re: MPG poll
67 Burban (2 1/2 tons of Detroit's finest) generic 350 with a T400 and 3.73's it got 12 around town and 14.5 at a steady 60 on flat ground. I voted 13 to 15. Every good story needs a bit of a stretch.
Since the upgrade to T350 and a Gearvendor I haven't done a MPG test but it seems to be the same around town (My foot is probably the biggest problem there ) and with the virus I haven't gone anywhere for a good highway test.Old threads and old trucks seem to go together. And at my age my best days are all in the past. Uhgggg!

Re: MPG poll
It's not 16 years old. Last post was 6 years ago. I never voted so thanks for bringing it back. And I thought I had it bad....look at those suckers getting less!
'72 K2500 --- 350/TH350 --- 4.10:1 Power Lok --- 285/75-16s It used to get 12.5 but seems more like 10 now. And in other threads Longhorn man has been coming up, so timely for this thread. Good ole Longhorn Man
