MPG??

[_sketch_]

Anyone actually know how much air con effects you MPG?
I drive a Mondeo 2005 2l diesel and for the last few days i have had my air con on full blast but used half tank doing 90ish miles?

Maybe my cars just crap.

I refuse to carry out any research on the subject as I only get an average of 19mpg without A/C anyway. There is only one situation when the A/C gets used and that's at the car wash when the engine is only idling anyway. I don't get the big fuss with A/C in this country.

Opening window FTW.

I've read quotes saying up to 20%, and other quotes saying that the extra drag of having your windows open negates any saving by having the A/C off.

I don't notice any real difference in either of my cars, a MK4 Golf and a SEAT Alhambra, (both 1.9TDi) as my driving style has a much bigger impact.

My car used to do 50MPG but has been creeping down to bout 39.

My air con works really well - frosty cool in seconds - only really been using it the last few days - especially as my car has black interior - really soaks up the heat when the sun has been on it.

Also i find having the window opend doesnt solve the problem of sweaty crack

Negligeable difference on my 316 poverty Beemer.

And after having climate control I'd never own a car without it now - opening window FTL in my opinion. I like to be bastard freezing in the car.

Do you have the car regularly serviced? Something like a blocked air filter is likely to lead to reduced MPG.

Not been serviced for about 9 months so its due - just spent all my money on a new bike so it will have to wait another couple of months

Might as well check the air filter as it costs nothing - if it's choked then you'll know why your fuel economy is poor. If not then you'll know it's something else. I can't see a replacement air filter element coming to more than about 20 quid, which will pretty quickly pay for itself in saved fuel if your economy has dropped ~20% and you do a reasonable mileage. Neglecting basic servicing is almost always a false economy.

Was talking to someone at work about this other week and as I always reset the trip when I fill up I know how it effects my economy. Been using it almost daily a couple of weeks ago in BMW 530d and it had no effect on fuel economy, about 47mpg, my assumption is that because the engine is a large heavy, torquey diesel then the pump really doesn't draw off much power, whereas a flimsy 1.6 petrol engine for instance is going to suffer quite a lot more.

I don't open the window because it messes my hair up

My trip comp says i am doing 350miles per full tank (used to be close to 500) but it lies like a cheap japanese watch! only does about 200/250 - well seems to be on this tank, its been getting worse every time i fill up.

I will replace my filter, its only couple of £, may have a problem with my MAF but its more likely the fuel re-map mod i have
Made a huge difference to power but something may have gone wrong - think i will take it off.

Mythbusters did aircon against windows open and it worked out the same MPG.

My Fiesta doesn't suffer much with the aircon on, but have to turn it off if I am needing to overtake something sharpish.

I have heated grips but haven't a clue as to how much more fuel the bike uses if switched on..

None, they only draw about 35watts, your headlights will draw 3 times that if you've got 2 bulbs. Aircon sucks power because it's driven by a pulley off the crank, put an extra load on the engine, makes more difference to a small engine.
