> Best fuel economy is to accelerate rather strongly to cruising speed, getting into top gear quickly
I have noticed that if I am accelerating strongly then up shifts happen between 2500 and 3000 rpm, otherwise the up shifts happen very much at 2000 rpm. Once I am in one of the upper gears then I tend to avoid heavy footing and accelerate gently.
I noticed if use a heavy foot, the box tends to down shift. This I have noticed in just the plain vanilla D mode and not Sport mode which tries to shift at top of the rev range. I don't regularly use the Sport mode.
On typical motorway driving, I keep at 70mph to 75mph between 2300rpm to 2500rpm. That is the rpm range and speed at which I have been able to get 40+ mpg.
I could try the "strong acceleration" theory and see if I get any better mileage... but I guess I won't see a massive improvement.
> People look at me cross-eyed when I tell them I run 40+ psi
Interesting. How far above the manufacturer spec is that :-)
My car is a touring/estate/wagon style and the due to the extra weight, the rear tires are rated at 2.5 bar / 36 psi ! Which I personally find to be very high. But I stick to the manufacturer specs.
Depending on how quickly you change your tires you may not notice the wear. I am too paranoid about driving on sub-par tires and so far have stuck to changing all four tires after 24 months.
