After I bought my 104, I changed the oil and put in Rotella 30 wt, well see how it does this winter for plowing snow, I use Rotella 5w40 Syn in my diesel car and always keep it on hand, so if it is hard to start, will be a quick oil change. The garage where I keep the 104 is typically about 20 degrees above the outside temp.
