Blackflag you need to keep it above the table. If you have a point of veiw.. good. But personal attacks show that you are running out of material. That is what happens when a person does not get their way, they revert to name calling. 4V and 3V = performance, that is a given. Fuel mileage... no way. More fuel VE and more is used and at a higher RPM. Case closed and end of discussion as for as I'm concerned. Just use common sense and the answer will come. The more fuel put in the more that is used.
