We've all poured a molasses-like substance out of the gallon of bar and chain oil at low temps (below freezing).
Recently I cut up a downed tree with my old saw in 30 degree temps and noticed afterward that the chain was hanging quite a bit afterward, like it had been over heated (maybe). It was a well broken in chain. I've seen that before a number of times.
It's probably true that the cold, slow-flowing-to-the-chain oil will slowly warm up as the engine disperses heat and flow better. But while I am willing to risk the slight extra wear on an old bar and chain, I want to keep my new MS660M pristine as long as possible, without stressing the chain during the initial cutting period.
Preheating the saw (in the house or warm truck cab) is probably the best answer. But can I safely cheat by switching to 5W30 in low temps? It pours about the same in cold weather as bar oil flows in warm. Well, maybe not as well but much better than bar oil.
Any comments would be appreciated....
