I should have prefaced that comment with; more recent vehicles within the past decade. Also, the older the vehicle gets the harder it will be for the computer calculation as injectors and the general tune of the engine can stray from the ideal parameters it was designed for.
More or less my point also, the fact that 16 years ago it could be within one MPG, then they should now days be within tenths of a MPG.
