Q: ok, I have always heard that the air conditioner uses more gas when turned on. Is this true? Does the heater also use more gas? I turned my heater on one morning last week (yeah, middle of summer and i need the heater... maine sucks ass) and I noticed the rpm meter move up a bit when I did, and went down a bit when i turned it back off. This was all while I was still parked in my driveway.
I was also wondering if Cruise control uses less, more, or just the same amount of gas if it's turned on or off.
Is there anything else that uses slightly more gas turned on when I'm driving?
