This is strange. I was idling today and using between .32 and .33 gallons per hour with a warmed up engine.

I thought it would interesting to see the effects of the defroster, so I put it on speed 1 (it goes to 4) and consumption spiked up around .42 to .44. Then, when I jumped to speed 4, it went back down to the mid .3's.

I plan on re-testing this, but that's what I saw.

What could explain better efficiency with a faster defroster speed? Was this some sort of fluke? Like I said, I'll retest this for accuracy.

MY SG-e is still in the process of being calibrated, but I trust it to at least be congruent with increases and decreases in consumption.
