What affects your MPG?

[RandallNeighbour]

I usually get 16-17 mpg around town. The 22-27 mpg range is when I have it on cruise control on very long trips and the cruise is set to 65.

What affects my MPG? Putting my right foot into it all the time... if I only had more HP I wouldn't do this as often—but my MPG would probably be a lot lower then.

My car is 2.7 which is smaller engine.. and 16-17mpg is mixed driving.. city only it drops to 14-15mpg..

I'm just worried something is wrong and I should fix it..
I think for now I'll just bring it more often to redline.. and stop looking at stupid mpg

Thanks

I get about 22mpg in mixed driving and up to 30mpg on the highway. Maybe your OBC is wrong. Try measuring the old fashioned way. Fill the tank, log the mileage, drive the car. On next fill up note the gallons added and just divide miles driven by gallons used.

Thanks Tpless, that's exactly how I measure it.. I didn't do OBC hack yet.

Thanks

Short trips with long warm-up times could make your numbers go down?

My right foot.

That is low. I can easily average 20MPG in mixed driving, and I'm not driving like grandma either.
