OIL question. I understand the importance of using 30W oil because of the high temp running of the tractors. but can 10w30 be used in cold temps for short work times like plowing the driveway (30-60 minutes) in the winter months here in Michigan with the temps in the 30s? Temp really puts a damper on getting the 129 started that once a week and I usually just heat the tractor up from underneath. my neighbors use the 10/30 in there newer tractors during the winter months but I've always wanted to stick by the book with my 129/169/and 1450
thanks
