Dave, I have been lambasted for my stand on engine oils and I respond knowing that I will be castigated for my opinion on oil. Let me clarify first that I am a lifelong Case mechanic since 1962 at the same dealership without a layoff and little lost time until recently while a health issue is being resolved. As far as your 870--- no multigrade is recommended for that engine in any of our oil charts from Case. A study of multigrades shows that MG oils do not change viscosity when hot so I will stubbornly recommend the straight weight oil for the 870. Case #1-- 30 wt is my oil of choice as I have watched it protect many engines over the years. The first engines Case had that recommended for multigrade in the large equipment were the CDC joint venture engines with Cummins introduced in the 580 E series hoe/ loaders and other equipment. There were a couple smaller skid steer engines that used a multi. I have seen engine failures which were directly linked to a particular brand which I will not name. My experience is first hand as I repaired a 530 Case ag tractor that the sleeve rubber o rings were reduced to slime, gooey stretchy snot and the only possibilities were incompatibility with the oil or the antifreeze. Since the engine was being used with an oil that it was not speced for it I will stick to the multigrade as the culprit. Seeing the carnage that an improper oil caused and being the one to repair the damage has left a lasting impression on me. I realize that was years ago and both oring and oil blends have changed but that incident is vivid in my mind and the cause for my opinion on multigrades. Before you all pounce, my life has been tractors, backhoes and skidsteers. I have been threatened with lawsuits by off brand suppliers and firsthand experienced the problems caused by two brands in particular. mEl

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day.
