True and thats what fuelly is for, real World every day averages by the public. But it's also good to see what you can get in extreme circumstances if you try. I see them as a target
I recently learnt that one of the techniques car manufacturers use during the lab tests, is that the car's ECU is programmed in such a way that it can detect when it's being tested in a lab! I think thats why if you drive really carefully and slowly, you can trigger this yourself.
