wow I just realized I only get 11 miles a gallon city driving within a 4k rpm range. Is something wrong with my car, the sticker said I should get around 19!

 

A whole tank for me lasts no more than 240 miles. So its not just me... I was thinking I might need to go for my 60k... I wonder if that makes a huge difference.

 

im asking the same thing!!! but the 19mpg i knew was never true

 

On my 2004 G35 on the Highway I usually get 28-30 miles per gallon. On the highway with 5w30 oil and 65 cruise set I can get 370-400 miles out of the vehicle.

I currently have 27,000 miles on my vehicle, but I purchased it with 7,300. In city I get about 22 miles with smooth shifting.

 

Mine's consistent with yours and I just reached 10K.
