I took a nice run today and finally was disciplined enough to set the cruise control at 70 and keep it there. I ran at a consistent 33mpg, but hit stop and go traffic the last 30 or 40 miles of my trip. Of all the days not to have a camera with me to back up the 33 mpg claim

You suck

PatOpsahl

Are you sure your computer is calculating correctly?
I have a 1992 and have been making many trips from Santa Fe to San Diego, about 870 miles one way. My dash says I am getting 21 miles per gallon. I manually calculated 25 miles per gallon.

That is interesting that yours marks 31. On my cluster, when I hit the 30 mark, it starts over and reads 03MPG instead of 30. And it won't go higher than that. Then when it drops below that, it picks up again at 29.

Almost look like one of your bulbs is out.

My dash says 24, but I really get 20. When my chip was burned they did not change the constant for the display. I have bigger injectors, so it getting more fuel per injector pulse.

Awesome Tim! You be safe Mr. Heavy Foot!

BADDUCK

I doubt if you are getting near that. Figure it the old fashioned way, actual use between fill ups.

MR NICE

My 85 gets 24.5 @ 80 to 85 on the e way actual mileage and the dash reads the same.

Thats not really possible, cause there is only 4 bulbs to backlight the cluster, and in that pic, all the relevant backlights are on without question. My 87 would go as high as you could get it, when on instant i got it to say as high as 70+ MPG rolling down a hill at about 85mph with my foot off the throttle. (would need a long downhill to maintain that!!)
Using US or imperial MPG? US gallons are not the same as imperial gallons.

Thats crazy!

I'll fill it back up today and figure it out. (If I can afford it that is......)

vettet80

how do you get such good gas mileage with a 421??? thats much better gas milege than my dsm ever got in the highway!!!

86PACER

Then why is one side dimmer than the other. I've had several of those back light bulbs go out, and it always looked almost like yours.

Casethecorvetteman

For a start it isnt mine. For seconds its displaying 31mpg which is certainly not out of the question. For thirds, if yours wont display anything above 29mpg then yours is rooted, not his. His is working fine but you thik its him with the bulb out?

Caboboy

Hold the fort............I'm bummed.

I filled it up and did the math, it works out to 27.25 MPG. Still not bad I guess considering the motor its got

cv67

THats awfully good for a big small block like yours.

Repzard

93 LT1 here
I get about 26 highway at 70-75 mph

86PACER

All irrelevant as to why one side of cluster is much brighter than the other side.

Demonic85

so the top left corner on my dash isnt as bright as the rest but I can still read it, no big deal. Nice gas mileage by the way

vettet80

and people in the 4 cyl world still think v8s get bad gas milage.... guys i thought that way once but now i really believe v8s can be very economical as long as you dont have a pb foot like i....
