868 miles on my 2009 Vibe, 2.4l, automatic, 90% highway driving, most at 70-75MPH, just started to use the air conditioning the past week so most was with AC not running. Average to date: 30.65 MPG

Our 05 generally gets around 35 mpg on the highway but we never use any sort of ethanol blend. Strictly real gas. That may have something to do with your lesser mpg. City mpg is usually around 27-29. Staying near the speed limit helps a lot, too.

About the cluncking when you go in reverse. Check if your exhaust wiggles, it may be a loose muffler clamp. My Olds had that issue right after I bought it and my father in law fixed it quickly and easily for free.
Good luck!

New, off the lot, I got 36.7 on a 90%highway run. Regularly averaging 32.5+ to and from work in a very hilly area, about 20% or less highway. This is an '08 auto.

maverick-
 
Although things seem to have changed a little recently, not too long ago one would expect their compression to rise through the first 10,000 miles of operation. oil use may be high initially. i purchased a new truck in 1988 that burned a quart of oil in the first 500 miles, but pretty quickly settled into normal useage. if you have been driving the vehicle mildly (low rpms, low throttle, proper warmup) you would expect break-in to take a little longer, and in the end, your engine would be better for it.
 I am aware that many now beive to break in hard (VERY HARD), and this doesnt cause the problems you would expect because nowadays there is an initial break-in at the factory. i am happy to report that mild break-ins have kept the engines in my 05 GTO, 99 Yamaha R-1, and the 7.4 litre in my yukon quiet and trouble-free.
on the other hand, 30.7 is pretty good, so i wouldnt expect it to get much better.
 
enjoy your car- my big-blocks are keeping me off the road!!!

Does anybody know how many rpms a manual transmission Vibe turns as opposed to one with an automatic at 60? I just bought a fully loaded one with about 18000 miles on it, but it's not getting the mileage I was hoping it would. Anyone care to shed some light on the subject?

Does the 2009 Vibe have a average/instant MPG display? If not how do you guys get your average MPG?

"If not how do you guys get your average MPG? "
 
Re-set the trip meter after each fill-up. Fill the gas tank up to the very top each time.
  
Divide the miles driven (from the trip meter before you re-set it) by the gallons shown on the gas tank.
  
MPG = miles driven / # of gallons used.

At 70 mph, my new '08 Vibe w/manual transmission runs at less than 3000 rpm, guessing 2800 rpm. I'll check 60 mph and post back.
 
I averaged 35.85 mpg first time I calculated gas mileage. It was all highway driving, no more than 70 mph.

At 60 mph, my 1.8L manual Vibe turns at about 2300 - 2400 rpm.
