My journey in to work today was slow. Super slow. So, while dawdling along the A14, I decided to reset the consumption and see what MPG I get in my
GTD with and then without the A/C on.
Without the A/C, I managed to get over
71 mpg over 15 miles. OK, this was at about 55 mph, but still a good number.
With the A/C on, it dropped to about
69 mpg. So, does A/C only cost about 2 mpg in winter (probably more in summer) or should I have seen it "cost" me more?
For the record, I had the temp on 19 deg, low auto.
