I recently got a 2007 Civic LX Coupe, and was wondering if anyone had any input on the prime highway gas mileage RPM for the engine? Lower isn't always better, and the gearing ratios as well as the recommended gear speeds seem to like 2000-3000 RPM.

 

Mine gets the best mileage at 0 rpm;

I realize its a valid question, so;

No fast starts/passes/acceleration/idling/hills, or anything that involves increasing engine speed and load.

I had an M5 so going to the honda has been a fuel dream!

 

94 del sol sohc vtec here, doing 80 on the interstate in 5th gear i get 32-35 mpg. country roads doing 65 in 5th gear closer to 40 mpg.

don't really have the associated rpms but will check.

never could figure out why there wasn't a 6th gear.

 

Lower rpm isnt always better? im gonna have to go with cameraman on this one. If i keep my rpms as low as possible and take off as easy as possible I always get my best mpg. I always shift at the lowest possible rpm when being economical. If you shift up and it stutters then you shifted it too early, other than that shift early and go easy on the gas pedal.
