I just got a question about mileage in my van, and it got me thinking about something I've been meaning to look into.
I've been measuring my dash odometer against the yard stickers along the interstate and against my GPS and see that it's off.
Not a tremendous amount, but enough that over longer distances it skews my mileage records for runs, my fuel mileage figures, and my planned maintenance intervals. That bugs me, of course.
Is this just a tire thing, you think, or is there a way to adjust the odometer to be more accurate? New odometer cable, or grease it perhaps, or some other way to effect the way it reads?
Do the Scan Gauges do their figuring off the dash mileage, or have a direct way to read mileage?
I'm running Michelin M&S2's in the size recommended for my '08 GMC Savana.
