Most fuel-efficient speed / best fuel economy?

[Free Bird-SKO]

Great, love to hear how it works out! To me it's not just about economy, range is a strong factor, lotsa times I'm driving around with a jug of diesel hanging off the back just to get me through.

FYI my mileage figures are all highway, summer fuel and I usually have added stanadyne

Yeh I hear you. Its all about range. Ive been using powerservice the grey bottle ive had a few injecrion pumps start sticking internally and the only thing that would free them up was the powerservice. I put on a 5300km round trip in the Great U.S.A and spent 1020 bucks canadian there was lots of highway. But a fair amount of citydrivin too.

Hey Jazty, what transmission do you have and what does your fuel mpg look like?

Are you coaxing me to offer up information that is properly related to the subject of this thread? Fine.. I concede.

I have a '97 b3800 short bus with a T444e, a 5-speed Spicer and 11r22.5 wheels. Rear end is 4.11, I think.
When I'm cruising the highway at ~100kph I'll be drinking 18 to 20 liters/100km. Somewhere between 11-13mpg.

Also take a look at this well-aged poll:
