I don't know about the manual but low temp rating for 20w50 is 10F (-12C).
Not to be a smart a$$ :harhar:
I ain't riding the oil can.
I will follow the manual's recommendations and my own experience in riding year round in PA. 20w50 is too heavy in January and February here. It may be 20-25 degrees in the morning when I leave at 6:00 am or so. I do always reach and sustain 180-200 temp on the way home at 2:00 in the afternoon as I get some ride time then.#@SasF#
I just worry about how quickly it flows at 20 degrees, especially if it sits for a few days because of snow or something. I also worry about not getting it up to temperature and sustaining that temperature to help cook water off.
Set a jug of 20w50 out now, and in early February open her up and pour her.
That is not a pretty site especially when our wear is at startup, and the heat is generated by friction, and that heat gets the oil to flow.
Also I have the dreaded "forged" pistons and they take FOREVER to warm up enough to expand.
Used to do it in all my cars until I got this turbo, 5w30 year round! And when I boost into 16 and 18 PSI she gets plenty hot.
So I guess it is application specific, and what YOU are comfortable with.
All this is my opinion and what I do, and my reasoning for doing it. Right, wrong, or indifferent :whisper:
