Cold weather oil indications
We had some issues with oil press indications in the cold, the first guy i flew with had several 206/185s. He used to fill the oil pressure tube with hydraulic fluid every fall.
I gots to tell ya it works like a hot damn, oil pressure within seconds, ask your ame if you have similar issues

The good old days -- mention that now and most AME's will look at you if you had 2 heads -- simply put in this day of CYA, it's not legal. I wonder if external gauges mounted on the cowls is an approved mod

What kind of temps are we talking here?
I've had my 185 out to about -28c and never had that issue
Re: Cold weather oil indications
It usually happens with a cold soaked aircraft (stored outside and plugged in) between -30 and -40 (40 being the cut off point) - no problems with a hangared aircraft. The issue a lot of the times was to get oil pressure indication for the initial start in the morning or after sitting for a couple hours with raps on.I've had my 185 out to about -28c and never had that issue

Re: Cold weather oil indications
Oil pressure should come alive withing 30 seconds of start.
Re: Cold weather oil indications
Flew lots of 185, 206, 207 down to -40 and rarely any problems with multi-grade oils. However we did clean the oil lines out with varsol if there were problems. This would introduce fresh engine oil in the lines.
Re: Cold weather oil indications
The oil theat was pumped out of the lines in the hangar could only be decribed as "grease"
Re: Cold weather oil indications
That and we are in a twin. The oil lines are about 8' long, all but about 2' is in unheated spaces
