I haven't personally checked mine, but based on some research (tests done by other people), it should burn around 1.5 gph right after a cold start, settling down to around .65 - .7 at warm idle. With the A/C on at warm idle, it should be around .8 or so. It's certainly a pig when it comes to idle consumption.
