~ave 65 miles/day (work is ~68 miles r/t)

Average mpg: 29.07
max mpg: 36.80 (IH10 to SA, cruise control at 74mph, no a/c)
min mpg: 25.94 (intown, beltway 0-80+mph, with a/c)
...using cheapest 87 octance available

mpg min-max variance: 27% (!)
std deviation (STDEVPA): 4.38

ave oil/filter change interval (as per "maintenance minder"): 6217 miles, 5W20 dino

$0.099 /mile ave (fuel only)
$0.126 /mile including tires (1 new set at $900!), filters, oil, misc

....ain't Excel fun?

I'd do that for my Regal but the results would be too depressing.

Not bad. Drop your maximum speed to 65mph, and your gas mileage will increase. I think—if my memory serves me correctly—you'll gain about one mile per gallon for every 5mph you drop down to 60mph.

"Drop your maximum speed to 65mph, and your gas mileage will increase. "

and the damage to the rear end will increase.

you've never driven much in Houston, have you?
j/t of course....;)

345 miles
31 MPG

Love my car.

My car does most of that for me now. 2009 Jetta Sportwagon TDI currently getting 31.4 MPG local, not driving conservatively. No good highway runs with it yet.

No, it's been many years; so many that I don't remember. Point taken. :-)

only 31.4 on a diesel? dang, you must be beating the tar outta that thing....

yeah, our old 93 Chrysler minivan had a console computer that gave you ave and instant mpg, estimated miles to empty and a lot of other fun stuff. Like 90mpg coasting downhill.....it wouldn't however tell you when it was next due to fall apart.....but that was an easy guess: within 1000 miles.

jonney, thanx, a few more are here:

Ken, you're such a geek!!

Only a Civic owner would keep stats like that.

Gas is less than $2, so it's time to go buy a Hummer or something.

One can only wish...My diesel has averaged about 15MPG over the last 72,000 miles...But of course it does weigh over 8,000 pounds and has 6 wheels......Ben

Not TOO hard on it...yet, but it isn't broken in yet and traffic on my drive to work SUCKS. Even on my motorcycle my milage drops from 35-40 to 30MPG.

Some of my driving habits from the Cobra may be carrying over. That thing gets 10-12 local, but 24+ highway at about a 90MPH average.

Yeah my diesel gets pretty bad mileage too. Empty I get around 6.8. Loaded light I can pull about 6. Loaded heavy, well Ive seen as little as 2.8mpg going across the mountains on I70 through Colorado. I can usually average about 5.5 loaded normal. Oh well those are the trials of hauling heavy equipment. Life aint easy when you weigh 120,000 lbs.
