So Fun Bus still has the 15w-50 oil in it. According to the Thermostat with
remote outside sensor this morning it was 12F. Due to the snow and my having
the Nokian WRG3 tires (235/55-17XL) and it being a Syncro I decided to take
it to work.

Turning the key the GoWesty starter turned the engine over with authority
and it fired right up. Oil pressure immediately went to ~80psi. I let it
warm up while I scrapped the windows, set up my phone to play music and then
off I went. I was driving gently as the roads were still covered with hard
pack ice and some snow. A few times the pressure made it to 90 psi. Once I
made it to the highway service road (~1 mile) the pressure was dropping
already. In ~2 miles I was getting it up to highway speed and the oil
pressure was going down under 70 psi.  After about 6 miles total the coolant
was near temp and the oil temp was catching up. With the oil cooler 165F or
so is all the oil will go up to. Oil pressure in this state is about 25 psi
at idle and near 60 at speed. This is for an engine at 290K.

BTW I love the way the Nokians work in this mess.
