The placebo strikes again!
There is SO much to fuel economy (as told by the EVIC) that .5 mpg is great, positive results are awesome but, well let me put it this way, with my 32" tires, my first tank of gas I pulled 14.12 mpg (calculated, NOT including the additional mileage driven but not counted due to taller tires), That was an entire tank of gas. The very next week I filled up and calculated 13.1mpg (again not calculating in additonal miles). All of that to say, a typical week with no major abnormal driving (other than less babying) I was down an 1 whole mpg. A couple clicks on the evic after 3 days wouldnt have me excited yet
