How is it that some people get such great MPG? No matter what combo I've had over all the years the best I could get was 9.5 mpg. In fact I barely got 15 mpg with a Windstar pulling a PU! And I know what some will say, slow down, etc. I know that so don't bother saying it here again. Then again math was never my favorite subject,it must be that new math you guys are using that I never caught onto.

Toyota digital odometers are programmed off by three percent in Toyotas favor. Shortly after Honda was exposed for a five percent error, in their favor as well, Toyota admitted to theirs being off. Both Companies stated that it was not done in malice, it was done to make their customers think they are getting better mileage than they are actually achieving. This was a few years ago, but it had been going on since the inception of digital odometers combined with vehicle speed sensors (in lieu of speedometer cables).

You wouldn't have a link to a factually-substantiated source for that (cough, cough) "story" would you?:R

This is not new news... I can only speak for GM trucks but go on any of the popular GM forums and you'll find guys who compare hand calc MPG figures to the DIC (drivers info center) reading always find that they are either spot-on or read high, BUT NEVER LOW. Imagine that...

Before people treat their trucks MPG monitor as the gospel they need to first characterize its reading by comparing to hand calculated figures for several tanks of fuel. My 2012 GMC Duramax has read 5-7% higher MPG from day one. Now that I have "characterized" it I just knockoff that amount in my head. Unfortunately many people don't bother with doing this and just "assume" its accurate.
