1) Is the rolling road BHP figure improved by using premium fuel , if so how much ? I put my Evora on the rolling road using regular fuel and it came up 9 bhp short of the Lotus figure
2) Tyre pressures set when cold are raised up to 10% more during warm weather compared with winter - how much would this increase the mpg ?
Idea - having had the key fob battery fail on the Suby , fortunately on the drive , rather than replace on a random basis for both sets of keys I now keep a spare battery in the car. I am sometimes slow but get their eventually ......

Do not know to be exact, but mine definately runs better on Super unleaded....it says use it on the the filler cap, and the dealer said you should use it to reduce pinking, which it does.
I have read posts before which seem to confirm the quoted power figures are accurate, but you can never be sure how accurate rolling road figures are. The actual engine power can vary due to air temperature etc, and a calculation is made to convert the wheel hp to enging power, so errors can be made here.

Its probably a placebo, but I think mine sounds better on premium fuel aswell..

Good idea on the key fob battery. Which battery does it need?

Re rolling roads, head to evora chat on tlf for some indepth discussion on the issue(s) and innacuracies of a RR especially the non-hub type.

Interesting point re fuel - I have only ever used regualr, never noticed anything untoward. Think for an N/A Lotus say just use regular? (that might be wishful remembering on my part). Perhaps Super is preferred for the S?
