depends on your climate. up in dovah you probably get close to 0 so you and the cannucks want 5w or 0w oil.

out here in california where "winter" means maybe 50 in the morning we have more choice. i run 20w-50 dinosaur juice year round and have no issues with oil pressure

I run 0W40 all year round in NC and havent had any issues. Only see 20's on occasion, I would just switch to a thinner oil.

That's your first problem. You can idle it all day long and the oil will not get very warm, especially on a cold day.

Drive a car to warm it up. Low load / low RPM's until everything is warmed up.

My Audi has an oil temp gauge, on a cold winter day it doesn't move on my way to work. Even after the coolant is all warmed up.

I thought 15w50 is good for up to -10 celcius. maybe i'm wrong?

maybe i'll switch to 5w50 then in a few weeks.

today the temps are suppose to dop down to -4.

according to the owners manual and checking some online sites, a 15w oil (15w50) should flow down to -15 celcius. The coldest it gets here is like -10 celcius.

so it is still necessary to go to a thinner oil.

my engine indles like **** and doesn't sound too happy when I start it in the cold, and I have a new engine temp sensor, idle control valve, vacuum lines etc. once the engine coolant temp has warmed up it sounds and idles much better.

well my oil pressure is good. on teh cold morning it takes like a second or two longer to get the oil pressure to jump up to 5 bar.
