Uh, don't think so. I mean even if its off 1-3 MPG we're still talking about 45 MPG from a full sized sedan that weighs in well north of two tons. The newer cars get better mileage than the older ones because of direct fuel injection, precision fuel metering, atomization and optimized injection timing that the old Bosch inline pumps couldn't even begin to dream about. I won't even bother mentioning the astonishing performance that accompanies the amazing frugality of these engines.
My trip computer economy is optimistic by about 1-2 MPG on the 06 CDI, my wife's GLK250 was spot-on the two times I checked it on longer trips. I've never seen my computer get to Tyler's levels but I have seen it at 46.5 MPG on rural two lanes at 55-60MPH.
Skid row's numbers just astonish me, the only way I could get my display that low would be to take a two hour stop-and-go trip by spending the first hour idling in the parking lot drinking coffee. Are you using full-throttle on every acceleration event? Wow. Have you ever taken your car on a 100 mile highway drive at 55-60 MPH?
