Car is a 2000 civic DX hatchback, automatic.
I removed the PS belt to see how it would affect mileage and not only did I get about a 2mpg bump, but the car is noticeably more responsive to drive.
Bummer is that it is sluggish to turn at slow speeds (more so than the manual rack in my CRX) and converting it over would be a permanent thing as far as I have seen. I'm sure I could get used to it, but the wife absolutely would not.
So for some of you either looping the system (keeping it wet, like here:
Power steering delete - Page 2 - D-series.org) or converting it over to a 96-97 CX manual rack is a good option for getting some mileage and pep.
For my wife's sake, the belts going back in, and I'll consider some other ways to recapture that lost mileage.
