City/Highway Mileage Differences - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When I picked up my new 86 a few weeks ago, I was pleasantly surprised at the mileage I got on the way home. The trip was mostly interstate driving and I was getting right at 18 MPG. I've just checked my mileage again which was mostly around town driving and I was amazed at the difference, only 9 MPG!

I know there should be a difference, but I never would have thought there would have been such a huge difference. Anybody else with similar numbers.
