Which report are you getting your numbers from?
Going from the Product Supplied report ...
EIA product supplied
These are the numbers I get ...
January 08 finished motor gasoline: 273,235
Divided by 31 equals 8.81 million barrels per day.
February 08 finished motor gasoline: 256,422
Divided by 29 equals 8.84 million barrels per day.*
I'm not arguing against your case. I'm just asking which EIA page you're pulling your numbers from, because they are different than mine. Using these numbers, per-day gasoline use increased in February.
Or have I got my math wrong? It's early, and that's entirely possible.
* Post adjusted to take 29 days this past February into account. Apparently, it WAS too early for me to do math.
