Why a diesel engine, with new petrol engine cars the power to weight ratio let alone the fuel consumption is incredible and they use mogas 25% cheaper than diesel. Another big saving would be in oil consumption, Lycoming HIO360D1A engine 1 litre at £ 5.50 every 2 hours ( include 25 hour oil changes here) or £ 5.50 per 150 miles. My car with 200hp engine £ 65 of oil every 15000 miles. Convert 15000 miles on a Lycoming that is £ 550 in oil !!!!!!
