I come to this subject a little late but I have a 'problem' with oil heating
rather than coolant temperatures.
My 912s has always run on the cool side for the oil temperature (standard
steam gauges) and on cooler Autumn days barely gets above 60dgrees. On take
off I do climb to achieve a higher temperature to try to burn off any water
that may be in the system.
I have heard of cowl flaps being used for temperature control but do not
know of any fittments to Europas.
Can anyone help?
I do use Evans without any problems on that side.
