Thread: New Hilux Fuel Consumption

No matter what fancy Diesel engine you burn diesel in, diesel is still only capable of yielding around 19 hp per gallon burnt per hour. Ditto petrol, about 12 hp per gallon burnt per hour. So if your Ute engine has to make, say, 80 hp to overcome drive train friction and wind resistance and vehicle mass etc to maintain a particular velocity, it’s always going to burn 4 gallons of diesel an hour.

Without improving the efficiency of the fuel, you cannot expect major gains in consumption.
