If you consider that a 5% to 7% speedo error on the fast side adds 5000 to 7000 miles to your odometer at 100,000 miles, that's a lot. It also inflates your fuel mileage. If you want to sell your ride, at let's say 150,000 miles by the odometer, you actually only have 143,000 on it,not much diff, but it will cost you.
I understand the reasoning behind it, as far as safety is concerned, but it's annoying to go somewhere and you know its only 400 miles and the odometer say's 420 miles, it adds up U know. I put 215/65R/16 tires on my '03 Forester to help correct the speedo error,and it goes better on snow and at the beach, has more PSI of rubber contact to the ground and the speedo agrees with the GPS now. Seems like SOA should have done that, but they may like the higher EPA fuel mileage figures and seeing us more often at the dealership.
