How are you Juke owners doing on the highway for fuel economy. So far with mine I'm getting 25.4 MPG. not so good

I'm about 60% highway and getting about 23-25 mpg.

Are you doing the fuel/mileage calculation yourself or using the car's computer. You should be aware that the Juke's computer consistently averages 2 mpg's lower then you actual mile/gal.

I know I calculate mine based on the miles driven since last fillup and the number of gallons it takes to fill it back up. Much more reliable than the computer.

Excellent point on computer MPG calculation. My Honda Civic Hybrid was always 2 to 3 MPG lower than miles/tank fill gallons calculation. I will watch.

Over 4,300 miles on my Juke. 60%+ highway. Car is averaging 21.4 MPG!! Horrible!! My calculations match the computer almost exactly.

Oh yeah, the sales manager says the car really hits its peak MPG after 9,000 miles. Anyone ever heard anything so absurd?

yes, most engines do take some time to get broken in properly. The piston rings take a while to seat properly and reduce resistance so that the motor can operate more efficiently.
Have you ever seen performance tests from the automobile magazines? They'll do yearly reviews.. The brand new 0-60 time will be like 7.2 and the 1 year later - 20,000 mile test will be 0-60 in 7.0. It's because the motors break in better over time and become more efficient.

Think about it.. You have a bunch of moving metal parts packed into a VERY tight space. Over time they wear against each other and smooth out the edges and parts that rub and touch.

The MR18s in the Versa take 8-10k before the break in well. We have multiple people that went from mid 20's to low thirties around that mark. I am curious if the MR16DDT will do the same.
