I went in to circle K (bad choice?) to get gas. I had a little under a half of a tank and about a tank ago I had some jerking so I filled it up with mid-grade. Here is the deal... It took 10.2 gallons?!? I wondered if something is wrong with my car because I had 67 MPG and about 530 miles on this below half a tank. Or do you all think it is worth reporting to weights and measures guys?
