88) Cycle the A/C if you have to use it
If you have to use the air conditioner, set the air flow to recirculate and manually turn the A/C on and off as needed. For greater efficiency, switch it on when under light engine loads or deceleration fuel cut off and off when under moderate/heavy loads. (Note: some newer vehicles do this automatically.)
Anyone know which vehicles do this? I was wondering about this recently. Is it possible to acquire this technology in an older car?
Thanks
