370Z highway mileage?

JB1 · 05-16-2011, 10:18 PM

Did a long road trip to the Virginia mountains last year, I got about 26 to 27mpg average on the highway. This at an average (and relatively constant) speed in the high 70's and measured over a full tank. The scangauge indicated an instant 35+ mpg every now and then, but that was at (much) lower speeds and perfectly flat or downhill bits... I really wonder how people get 30+ mpg average on a full tank. 45mph constant on a perfectly flat road and tailwind maybe?

No, just drafting behind a semi gets me 30+ mpg.

On a side note, does anyone know why our cars get so many rock chips???

I do not think I get much better than 25 MPG, but I can't seem to keep it at the limit, so I do not know the real potential.
