The 767-200's and 300ER's at Delta burn 1 pound of fuel for every 31.0 pounds of weight at optimum altitude and .801 mach. Example; 300,000 pound cruise would equal 9,677 pph fuel flow with the above parameters.
If you're interested, the 400's stretch that to 32.8. The difference is attributed to the raked wingtips.

According to statistics a boeing 767-200 departing with max T.O weight will burn about six tons for first two hours & sure fuel consumption will decrease as weight decrease that can end up to four tons per hour.
