Anywhoooo I think the post should have been MPH/MPG/Wheel Diameter since MPG is affected also by wheel diameter. Upgrading from 18" wheels to 20" wheels is gonna make a difference for sure and most people on this forum have aftermarket wheels.

interesting point. don't people get their odometer/speedometer fixed when they change wheels? that would result in accurate MPH/MPG readings. otherwise i'm not sure why anyone would post if their MPH/MPG are wrong.

Who here have you heard about corrected their speedo after a tire dia change?
The weight of the wheel can have an effect on MPG.
Also our computers are not very accurate as it is, have you actually calculated the real mileage compared to the computer?
And from a past post, some of us knowingly or not have gallons set on imperial instead of US.

to note on that, how would you calculate exact MPG? IMO if you go to a different gas pump and fill up and calculate MPG that way, it's not going to be accurate either since each gas pump surely cuts off the fuel (i.e. thinks you're topped off) on different intervals anyway, changing the total amount of fuel in your tank and thus affecting the MPG.
Changing wheel size does not necessarily mean tire diameter change.

and MPG UK/US, i would say since i'm in the US and i started the post, it would make sense people on the UK digits would convert, but as i mentioned earlier, people with problems reading instructions most likely are not going to do that. in the meantime, i'll post what people provide. if they don't know how to follow instructions and post meaningful information, i can't really help it!
