12mpg...Sound about right w/ 4.10s + roof rack?

it could be a bad diff sensor. mine would read about 80% of the time but you couldn't tell while driving.. then it slowly died until I had no speedo at all.

what does the OBC say? if the injectors are stock it's quite accurate. that's assuming the cluster is bad and not the diff sensor of course.. it still needs VSS to function.

i don't have an OBC read out for mpg....just the standard clock/date/outside temp Was on my list of 'upgrades' but never got around to it.

did an approx calculation based on my commute distance:

approx 270-280 miles > full tank w/ A/C cranked to setting 4
avg 19-20mpg highway

Sound about right?

Mpg

I got 265 to a tank this week no aircond mixed city and hwy avg 17.5 mpg using 15gal prem chevron

i calculated the different in mpg with my roof rack on my e30 a couple years ago... was 2mpg worse with the fairing and 1mpg worst with just the bars+bike attachments. this is of course highway mpg, and city mpg it wouldnt make a spit of difference.

[mclawrence]

I used to commute 1 hour each way and on the expressway doing 65/70 I was at 19/20 mpg.if a took the highway doing 55/60 I would get 23/24 mpg.over 20+ years and 3 different ix's the average was pretty close according the obc's
