Well, EIA figures say that refinery averages for a 42 gallon barrel of oil are 12 gallons of distillate fuels, 4 of jet fuel, and 19 of gasoline. The H1 is supposed to take diesel; but for the sake of handwaving and round numbers; we’ll assume that it’ll burn some mixture of those. So call it 35 gallons of fuel per barrel.
176000/42= ~4,200, so very ballpark figure of 145,000-ish gallons of fuel. H1 fuel economy figures seem to hover around 10mpg, so I’ll call it 14,500 miles. How long that takes you is between you and local traffic enforcement.
