Lynn has posted several times that oil temperatures ABOVE 16= 0F rob power from the rotary, so that should mean oil temps below 160F are a g= ood thing.

How low is too low?

On my last flight the oil temp was about 135F in cruise R= 30; with synthetic or multi-viscosity oil (15W50 for example), low oil temps sh= ould not be problem.

I have to say that it is also running too cold, it goes down to about 16= 0 F (oil and water) when coming in for a landing which is usually 3500 rpm.&nbs= p; I have the NGK iridium plugs, lead RE7C and trail RE9B.

 

I am trying to warm up by blocking the radiators at the moment.  OAT&nbs= p; between 30 and 40 F.
