Here on the south east corner of Superior we do ocassionally get significant snowfall at -30* C. and colder in the early winter until the big lake freezes up some. I've been using the manufacturers recommended lubes , but my MF GC2310 will be due for an oil change at 450 hours this fall and I'm thinking synthetic for easier starting. The block heater isn't quite enough at those temps.
I've used Seafoam in my gas engines, but haven't used any additives in the diesel, yet. I get off road diesel in my jug, when I gas up on the other side of the border, and it has a little higher sulphur content.
I'd go with the manufacturers recommended hydraulic fluid. If it's like mine, it lubes the gears as well. My GT's use Dexron III for hydraulic and rear end lube, and there is nothing underpowered or lightweight about a MF1655. It weighs as much and works as hard as the 2310 in the winter.
