Just read a few efficiency tests from Nebraska Tests. LP is always the least efficient. But, LP is cheaper so usually - gas is the most expensive to run, LP the second, and diesel the cheapest. At present, the National average price of LP is $1.50 , reg. gas is $2.87, pump diesel $2.87, and farm diesel $1.90. For example - a Deere 4020 with Syncro trans. LP 4020,95 HP, 7.9 horsepower-hours per gallon Cost 19 cents per horsepower-hour. Gas 4020, 95 HP 9.9 horsepower-hours per gallon Cost 29 cents per horsepower-hour. Diesel 4020, 95HP 16.4 horsepower-hours per gal. Cost 11.5 cents per horsepower-hour. Farmal-IH 706 LP 706, 76HP, 7.4 horsepower-hours per gal. Cost 20 cents per horsepower-hour. Gas 706, 76.5HP, 9.5 horsepower-hours per gal. Cost 30 cents per horsepower-hour. Diesel 706, 76HP, 12.4 horsepower-hours per gal. Cost 15 cents per horsepower-hour.
