JasonA Posted June 17, 2008 Report Share Posted June 17, 2008 This is a general question -- applies to Caddies and everything else. Is there enough of a gain in A/C efficiency to warrant using the "MAX A/C" or recirculate option almost all the time? Knowing that the A/C has to remove both heat and moisture from the air, it's understandable that recirculating relatively cool and dry air in the cabin would be more efficacious than using hot and steamy air from outside (especially "southeast" hot and steamy air). I know that on the AUTO setting, the car will often use the recirculate mode automatically, not even necessarily lighting the recirc button when it does it (so you never really know). But would you save some compressor wear and tear (and fuel economy) by running the A/C in recirculate mode all the time...and just bumping the temperature up a little bit if it got too cool? Methinks it'd not really bring any measurable fuel economy comparisons, but it's food for thought anyway. Jason(2001 STS, White Diamond) "When you turn your car on...does it return the favor?"
