My Honda is 23 years old, I would think that any issues it came with have only been made worse over the years. But for me, since I don't use GPS or any other instrumentation to verify my results, I am not super concerned with the accuracy of the odometer. Maybe I avg 37 mpg, maybe in reality it's 34? The part that interests me is the improvement I can make in whatever number I am getting. I am assuming that any issues with accuracy are at least consistent issues (ie being off a few percent when new compounded with years of wear), so as long as everything stays at the same level of broken then I can at least track my improvements!
