When the frigid winter weather comes around I just add a bit of diesel fuel to my oil jug. Keeps my bars/chains happy.Last winter, you noticed your chain moving like it was stuck in molasses, and come summer, it was splattering goo everywhere.
You finally decided to change things up and used lighter oil in the cold and heavier oil when it’s warm.
Now, the bars stay cooler, the oil flows better, and you’re no longer scraping sticky residue off your saw.
