DC-2 Engine oil measurement
I am doing a bit of research on the DC-2 at the moment and looking at an old American maintenance card it states “8” for oil in the engine and “210” for gas in the engine before a flight. Am I correct that this would be US gallons for the gas (petrol)? But I am not so sure about the oil? Would this be in gallons or pints (US) could anyone tell me?
Many Thanks
