I have been monitoring my fuel economy since I got the valver and have made a strange discovery.
Based on: Fill right up till no more can go in. Run car till near empty, take note of milage, refill till no more can go in. Work out fuel econ.
When I first started using the car, my first 2 fills were around the 35mpg mark. I drove it a 'little' harder, and my economy dropped to around 31mpg. Past 2 fills, I have ragged the car a bit taking it upto the limiter many times. I returned 35.8 mpg!
So my question is... WHY? Why if i drive harder to i 'seem' to get the same or better economy? I can't remember if I was using super or regular, but will experiment with this later
My calculation is: Milage divided by gallons required to fill when near empty get mpg.
