My knowledge is a little agricultural. I have been a technician with industrial turbines in the past. When I used to spend a lot of time in helicopters I understood drums had a life of 6mths. I'd 'harvest' a lot of jet A1 to clean car parts in for this reason. Jet A1 is closer to kerosene than diesel. I don't think it would be close enough specification to run in a late model reciprocating engine like your Peugeot . I'd wonder about the "lo sulfur" requirement. The bad side of sulfur produces sulfuric acid which is corrosive to engines (reciprocating). But the lo sulfur fuel was also known to leach plasticizer from soft engine components until they put an additive in to compensate. Generally speaking the limitations on the power a gas turbine produces is the temperature at the first stage power turbine nozzles. Eg too high a temperature will cause metallurgical degradation limited life and even failure. A gas turbine can run any sort of hydrocarbon fuel if it is jetted correctly. My interpretation is that a GT is very tolerant of variations in fuel so will easily handle diesel/kerosene but petrol would be too hot. As compared to modern recips that have very tight octane tolerances. Australia's emissions laws specify lo sulfur diesel but do acknowledge our regulations and industry control is very poor. However if the manufacturer specifies diesel, I'd use it straight from the bowser.

The advice is that I should use Jet A1 rather than diesel as it must be low sulphur diesel and that is hard (apparently) to guarantee here. So I beg your indulgence about a few issues 1. What is the shelf (or tank) life of Jet AI? 2. Will that shelf life depend on the sort of tank it's in (aircraft, jerry can, 44 gallon drum etc)? 3. Once Jet A1 has passed its (aviation) use by date, can I use it safely in my diesel car (as that would be a way to avoid throwing it away somewhere). 4. Is low sulphur diesel really that hard to find (guaranteed) here in Australia? 5. What other things should I be thinking about in terms of fuel? -- Robert Hart [email protected] Darling Downs gliding weather information <http://the-white-knight-speaks.blogspot.com.au/> +61 438 385 533
