I'm puzzling over the owner's manual (typo?) stating that the fuel tank capacity is 18.5 gal (US). When I filled the tank at very close to E (empty), it took 14.4 gallons. I had run it down to where the warning light came on as part of my checking and calibrating the gas cuage ritual. The numbers I had gotten earlier when checking the fill at the half and quarter tank marks seemed odd based on the stated capacity. I now think that the manual is wrong and that the US capacity is 15.5 gallons, which they list as the British capacity (15.4 Imperial gallons). Or is my gauge just completely whacky? Anyone know anything about this?
