It is already pre-programmed with a number of heavy fuel oils.įor your oil, you should have at least one defined viscosity at the reference temperature, which you quote (150 - 480 cST 50C). I imagine you need to determine your heater control temperatures.ĭownload spreadsheet ASTM D341 from here: RE: API 13 Fuel Oil Viscosity vs Temperature

On the other hand, intermediate fuels and above are blended for their viscosity because viscosity is significant in the efficiency of operation and is controlled through fuel heating. there is no compensation for viscosity in engine management. Viscosity is no less variable but because, for light diesels, the viscosity is quite low, it is often disregarded (except for power factor correction injector performance testing etec.) i.e. I wonder if this is the description that you have (though API 13 sounds low, those that i have found are in the API 20-30 range). A common practise appears to be to refer to the API specific gravity measured for the batch. This means that deifferent batchs od diesel, and for aviation fuels, the density and viscosity can vary according to the conditions at the refinery.ĭensity can vary significantly (especially critical in aviation fuels where different batches are sepearately stored).
