One thing nobody is talking about is the tire correction factor. You need to increase your miles shown on the odo to what you actually drove. This is because you are getting lied to by the odo seeing as it still thinks you have a stock tire size on.

Correct this and see if your milage numbers don't look somewhat better?

Good point. Here in Idaho, and in other states I'm sure, they have "speedometer check" zones on the freeway. These zones are 5 miles in length and there is signage at every mile to allow you to calibrate your speedometer. It isn't an exact science; the driver has to "eyeball" the exact instant the vehicle reaches a mileage sign against what the odometer is showing.

I have determined that my '93 is reading slightly low; therefore my MPG should be corrected by about 2% higher.

Good luck
