As I'm new to my Yak52 I have a question of the group>>>>

The M14P operations manual calls for oil dilution with gas for extreme cold weather operations. I also understand that winter preheating is a requirement of the oil tank, sump and oil cooler.
Has there been any consideration given to use of a lighter grade / multi grade oil in cold weather or is there any modification for bypassing the oil cooler with a thermostat until the oil reaches operating temperature?

Do not dilute the oil with fuel. Use Philips 25W-60 multiviscosity aviation
oil. It was designed for radial engines. The oil cooler already has a
bypass valve in it. It is always a good idea in colder climates to preheat
the oil tank, sump AND the oil cooler before starting. Even if you preheat
the oil tank and sump, you don't want to take the chance the oil in the
hoses to and from the oil cooler plus the oil in the cooler itself can
damage the oil cooler. Just use common sense when preheating.

We use Phillips 25W60 av oil,---Works great, and less concern with cold
starts.

Jack,
We use the EZ Heat Engine heater to pre-heat oil in the tank.  Works VERY well.  

Cheers,

Barry
