Is it a good idea to set climate control to 'A/C off' during the winter ? I usually have it set to off, it seems to give more MPG

 

With the A/C on, you always get lousy MPG. I leave mine off as much as possible. I like driving with the sunroof in the back end up position with fresh air coming in through the vents. In the summer, you really don't have a choice, unless you like melting into the leather seats.

 

ac on even with heating wastes extra gas?.. maybe this is why my car only gets 18 mpg even when i drive conservate for the full tank

 

I keep my a/c off in the winter but turn it on once a week as the freon lubes the internals according to my mechanics. Helps the compressor last!!
