just drove from louisiana to Destin, Florida.. and i am amazed, my ms3 got about 30-33 mpg on the highway.. at half of a tank, i got 200 miles on her, when i fill up it is about 12 gallons on E soo.. thats about 30 mpg!!! didnt know she had it in her to do that well.. that is cruising at about 75-80 the whole way..

I believe you because I was getting about 26- 28mpg from Orlando to Tampa (HWY) and I wasn't exactly being easy on her.
 
Those are notoriously inaccurate. The only way to properly measure gas mileage is to fill it absolutely full, drive it, fill it absolutely full again. Then do the math. Filling "to the brim" is not a good regular practise.
 
I get 220 or more by 1/2 tank, But i am getting 385 miles to the tank.
I dont think you can get that mpg based on 1/2 tank of gas only.
You need to wait till the yellow light comes on, pump gas till fill-up,
see how many gallons went in, and then drive till the yellow light
comes on again. Dont forget to set your trip odometer. Then you
can average out your MPG.
 
well that will be tommorow, but ill top off at almost 400 miles to this tank.. soo.. its still damn good..
 
guess i never tested the guage when i had the 3, probably should have now that i think about it, and i definitley will when i pick up the ms.

when im on my bike i just end up filling it up every 120 miles (cuz there's just an idiot light on it)
 
my mpg calculator on the display pretty accurate as far as hwy mpg's... but reads high when I mix hwy/city driving.
 
Flyer, you can't look at a fuel guage and get any kind of accuracy at all; that's the only measurement he made. Fuel guages are notorious for "picking up speed"---as an earlier post said, you almost always get a significantly higher number of miles from the first "half" of a tank if you are only looking at the guage.

Also, you don't have to run it down to the yellow light to accurately measure mpg, nor do you need to "top it off". Next time you fill up, just let it click off normally, then reset your trip meter. Then when you fill up again (at 3/4 or 1/2 or on the yellow light) note how many gallons it took to click off and how many miles are on the trip meter. Easy.

Roops... that's what I get for reading too quickly while I'm at work (chair) . Yes, definitely not an accurate way. The gas guage lies.
 
wtf? You guys must be doing lots of highway driving to get those kinds of mpg. i drive city/highway mix and i'm averaging about 22-23mpg
 
I average 24-26 with a 62 mile drive (98% freeway at 75mph cruise)every day Mon-Fri and about another 100+ miles on the weekend. I do 425-500+ miles every week.
My wife and I purchased her 07 Jetta in April 07 and as of today it has 25,000 miles on it. And that is just her car. Together we do like almost 50,000 miles per year!
