my car gets ~350 miles to a gallon when it's all highway, but only around ~250 when it's local. I shift around 2700 rpm each gear, i figure that'd be the most economical rpm range to shift right? But it's a little too low to make power at each gear.. what about you guys? any specific rpm to shift at would be more economical?

 

why is economy a stressed issue?

 

I usually shift around 4000rpms. I still get good gas milage, and I have a little more fun.

 

hmm... well the money I can save on gas, can be used to purchase other desirable goods..

and it's not all about gas mileage... i was also wondering what's a good rpm range to shift would be best for the car.

 

sane driving is till get good zoom and eco 3000-3500 state of tune, staying off the hi-cam is sometimes a good thing

 

I have and auto tranny, and put an igniton setup in. The results were about 22-30mpg extra in the city. I can only imagine it doing only better on a 5 speed.
