ATF oil is an oil for automatic transmissions, it was never meant to be used in the combustion part of an engine and it is not dissolved by glow or diesel fuel. It can possibly be used for long storage/conservation of engines but not in between flights or weekends.
Try a dedicated after run oil instead, these are compatible with our model engine fuels and gives you very easy first-starts.
