AAAAaaaaaaaaaaarghhhhhhh!

I drained the tank, topped it off, hit the trip reset and started my
experiment. I drove down the tank until darn near empty using the air
conditioner on recirc for the entire tankful. Last night the little
lady ran some errands and put $10 in to get her around! See what a lack
of communication with the spouse causes, you youngsters?

Anyway, I usually average maybe just under 300 miles before refilling,
but with the air on I was right around 200. That's quite a big hit for
the air. My guess is that with the drop in HP with the compressor
running, I tended to floor it a bit more. I ususally am a right-laner
driving the Civic (like what other choice do I have?), but the leadfoot
level went up running the air. I found myself flooring it forcing a
downshift more often. Leadfoot level went up to around a 7-8 out of 10.
IIRC some manufacturers tout a 5-10% drop in fuel economy with the air
on, but I saw quite a bit more drop, albeit somewhat unscientific in
method.

Thoughts?

For the sake of facts, it's good to lose the word 'tank' and substitute the actual volume of fuel, either gallons, litres, whatever. Otherwise, it's kinda like hearsay, or gossip.

There's only one correct way to explain fuel mileage: How much fuel was used to go how far.
