Thanks. I did know it can be done, I just haven't bothered. Yet.
Over the long term (almost 28,000 miles and 950 gallons pumped) it's been optimistic by 4.3%, so a 4% adjustment should make it very close.
I think it's possible for owners to get to the menu to make this adjustment with the right magic incantation of trip-meter button pushes and ignition on-off cycles, but I'd have to find that again.
At some point soon I'm going to reset the "lifetime" MPG indicator; it stopped counting fuel used at 270 gallons (~1024 liters) about 14,000 miles ago and recently seems to have stopped counting distance traveled, holding at 76.2 MPG after linearly increasing for about 12,000 miles. I'd been watching it to see what happened long term. I may adjust the indicated MPG computer at the same time.
