okay i have always ran CASEIH 15w40 NO1 heavyduty diesel eng.oil.
friday i noticed that parts had some CASEIH 0w40 NO1 full synthetic heavyduty diesel eng.oil.
they got it from one of our other stores and the parts man will give me a good deal if i want some.
whats the deal with the 15w40 regular oil compared to 0w40 full synthetic,is it better for the cold weather here in upstate ny,or should i just stick with the 15w40 regular oil that the old girl is used to?
