And the speedo should be off as a percentage ,...as long as it is on zero when the vehicle is stopped.
So the faster you go the more it is off/ the slower you go the less it is off.
at least that is the way that 99.9% of speedos that are off behave.
If it in cable driven you can usually buy a different gear for it.
If my calculations are correct you should be about the same amount (8% high) in your MPG figures IF the odometer is off by the same amount.
Look for a speedo gear with 8% more teeth to correct the speedo.
