I seem to remember reading here at BITOG that the cold flow properties of multiweight motor oil deplete whenever it gets "cold enough", whether the oil's in the crankcase or sealed in the bottle/jug. If I have this wrong, someone please set me straight.
Assuming this is true, would it be better to store oil inside the house, where we'll assume the temp remains well above freezing? Or am I splitting hairs here? Some of this oil is already a couple/few years old(Lubro Moly 0w40 SJ synthetic), it'll probably be 2 yrs or more until I use it all up, & I have no idea how it was stored before I bought it. The jugs were pretty dusty, though. I should also add, our winters here are usually mild. Most years, the lowest temps we see are ~20 deg. F(~-7 deg. C) or a bit under. So, should I bring it in the house, or leave it in the unheated carport closet?
