To save on money, will red diesel work in a model engine. as it is acualy oil, it will lube the engine aswell as fueling it with no additives. as in the UK red diesel is only 39pence a litre, cheaper that 10 pounds a litre for the model stuff. we have a large bayliner fishing boat with 50 gallons of red diesel in the tank. as its not being used for a while, i cound pinch some if it will work. sorry, i blabbled on again.
