got my fuel issue squared away now...27 mpg
One of thing to consider with fuel economy is excess weight, especially in a lighter car like the MP5. Empty your car of any excess crap that isn't needed. You'll get a bit more pep too.
Also, I use the cruise whenever possible, and I drive 60 in a 55. As the link below discusses, fuel economy usually increases dramatically at speeds above 60. I used to drive 64 on my way to work, and by slowing to 60 my average fuel economy went up by 2 to 3 mpg. Now, I don't advocate doing 60 in a 75 zone, that's just dangerous. Keeping the tires at proper air pressure has many benefits (better mileage, better tire wear, etc). It all adds up. My MP5 manual averages 31 to 32 MPG. I've seen as high as 34 on a couple of occaisions.
Here's a few more tips:

I wonder if those that are getting really crappy mileage (20 or less) have bad O2 sensors?
Don't you mean that fuel economy DECEASES at speeds above 60?
My wife and I just drove from Idaho to California. We got about 350 miles per tank and averaged 29-30 mpg. I thought it would be a lot more than that. My bro-in-law reported that they got 38 mpg. I don't know if that was a mistake or not, it seems like an awful lot. My inlaws have a Honda Hybrid and they are getting in the 40's, so 38 mpg on a non-Hybrid seems a bit odd.
It's possable to get 38mpg on a non hybrid but it depends on the car and if its all hwy. I used to get that in my old ford aspire... now thats a car that has no power but good gas milage.
LOL...I used to avg 35-36 with my aspire. When I first bought it a fill up from empty was about $7. P5 has worse mileage but more power and better looks.
This winter I avg 22-23 for the season and roughly 250-270 miles per tank. I did have a couple of tanks exceed 300 miles.
My sedan with a sport auto typically gets 25 mpgs per tank. Doesn't seem to matter what the weather is like or which tires I have on (winter 195/55-15 and summer 215/45-17).
I've drained several tankfulls with non-stop interstate driving at 75-85 mph and got roughly 22-23 mpgs. Usually fighting a head or cross wind at the time too.
