ShaggyZr2, I was thinking pounds, duh

128 is correct.
551,000 tons of cow dung equals 1,653,000 gallons of fuel a year ????
551,000 X 2000 = 1,102,000,000 lbs X 16 oz = 1.7632 to the 10th divided by 3.5 = 5,037,714,286 X .042 = 211,584,000 divided by 128 oz = 1,653,000
Same as you got, good catch
Corrected now
