I found the recycle button! Had the car 9 months and had never even noticed that button. To think my profession involves observation too!
I really doo rely on my CC to keep me cool; I'd be super aggressive if hot and stressed behind the wheel. However, as soon as I can I open the windows - the car just feels too sluggish with it on.
MPG wise, if you accelerate a little more slowly, allowing for the drain of the aircon, and drive both motorway miles and town driving you will not notice little or no reduction in MPG. I have driven other 18k in 9 months in my 172 and really believe this.
'air con is great...then i looked at the mpg (after 2 hours parked on the A43) 22mpg'
DRIVE THE SAME ROUTE AGAIN WITHOUT AIRCON AND SEE HOW POOR YOUR MPG IS...
Sorry for the shouting
