Today I needed to add oil to the chainsaw, it was in the teens outside and the oil poured very slowly. It was almost like maple syrup. There was even a continuous line of oil from the funnel after I moved it away from the saw. I assume after about a minute of running the saw would be warm enough to compensate for it, but I wonder if it would be better to store the oil indoors when it's this cold, even just so there wouldn't be such a mess.
