They don't know how to do math on that engine.
WOT of 45 knots burning 13 gph is about 3.9 miles/gallon, not .29 and cruise is 5.8 miles/gallon. The range is off a tad, but at least it's close.

The quoted figure was gallons per mile, not miles per gallon.
WOT burn at .29 gallons per nautical mile is 3.4 nautical miles per gallon, or 3.9 statute miles per gallon.
Cruise fuel burn at .2 gallons per nautical mile is 5.0 nautical miles per gallon, or 5.75 statute miles per gallon.
