I have about 750 miles on my 13 WRX hatch, and I normally average around 24.6-25.3 MPG on the trip computer. I filled up this evening and reset the trip computer, and drove like normal. 2 miles in, my avg. mpg started going up to 28 and even topped out around 30.3 mpg, then held steady around 28.5 which has me very suspicious of a potential problem.
Has anyone else had this weird situation happen before?
