Speedometers regularly read low, but I'm not aware of odometers reading incorrectly. I would think that those would have to be pretty darn accurate from the factory (<1% deviation) due to the implications to warranties and the fact that odometer readings are strictly regulated.If I were Jon I would use the GPS on my phone to assure accuracy of the Toyota odometer when calculating gas mileage. I had at least 4% on my 99 4Runner until I upped rims to 17" from 16". Then mileage was spot on. I think the barristers force the inherent error to avoid legal issues on speeding tickets.
I liked the video as he gave good trip info and comparison to his 4RUnner (with the roll down rear window). THanks for posting.

Are you sure that there wasn't something out on your '99 instead? Previous owner put smaller tires on it or some non-OEM tires that don't measure exactly the same?
