So it appears that I might be the only in this forum who may have experienced this I call a phenomenon. My gas mileage now stabilized at 27.1 MPG (roughly 60/40 highway and street driving respectively) after 2 full tanks worth of gas since my service was done. I'm not as concerned about the accuracy of the computer, but more on what may have been done to the car to begin showing a higher gas mileage. Perhaps the only way to confirm if the computer is accurate is to do a manual measurement, which I will do in my next fill up. I just won't have a baseline manual measurement since I didn't do it before the service.
