What weight of oil do you WD owners us in your tractors? I live in Northern Minnesota. How about using regular 10W - 30 oil winter and summer? I don't use my tractor hard. I move bales for 2 horses. A few hours of mowing the pastures with a brush hog. Moving some firewood. Moving snow. It doesn't smoke or use a drop of oil now and I want to keep it that way.. Thanks for any info guys...

We have a WD in Omaha, Nebraska. Most use is pushing snow. We run 10W30 all year round.

The old way was to use:

10 weight below 0
20 weight between 0 and 32
30 weight above 32.

Now 10w-30 covers it.

We use Valvoline 10w-30 all year in all are Allis Chalmers.

Same oil in the air cleaner as the crankcase. 10W30 is better than any oil they had when that tractor was new.
