Modifications to increase gas mileage?
Other than inflating tires (reducing rolling resistance), and aero modifications, are there any powertrain mods that will actually increase the mileage of the vehicle at highway speeds?
Thanks

I'm averaging around 38mpg on the freeway, but the city driving nukes it all to hell. Combination I get about 32mpg when all is said and done.

i figured cruise control would be worse than being mindful of what's going on in traffic around you, since you have to brake to "break" the control instead of just coasting down to match speeds.

That's REALLY babying the throttle and making sure to coast at EVERY opportunity. I hit 42mpg on the way home from work thurs, but it was right after a fill up and lots of coasting. But I'm also in DFW Texas and it's fairly flat here.
Begs the question as to how accurate the Fuel Tank Avg readout is though.
(I know the picture shows 40, I hit 42 afterwards, but I was getting close to traffic, and couldn't pull out the phone)

install ISF under car shield do reduce drag and dont fill up gas tank over 1/2 to reduce weight. Install tires with low rolling resistance. If you have is250 lower the car so you dont have the wheel height of an suv lol

Already mitigating using my brake pedal as much as possible to maintain steady speed (coasting as much as possible to slow instead of wasting the power used to get me to that speed).

The best I could do is 26 MPG on my IS250 and I am extremely happy, I hardly have to fill up gas compared to my last turbo awd car.

And no, I meant 38 and 32. The car is sitting pretty stable at 32 mpg atm (with city driving taken into account).
that's a few miles lower than my IS350 sir lolz....
