Hey, I am no expert, and that is why I asked the stupid question. I since have looked at other post that indicated fully synthetic 10w 30.
However, I e-mailed Stiegmeir and specifically asked if they used mobil 10w 30 synthetic and he cordially did not answer my question only stateing that a blower port comes with new oil.
I called tech at eaton and after he told me it did not need to be changed for 180,000 miles, I asked if I was going to change it, I had heard that the oil in them from eaton is basically 10w 30 synthetic and his reply was "absolutely not." He then proceed to tell me that I can get it at gm or ford but gm usually carries where ford may not.
I don't know what any of this means about if 10w 30 is ok better or worse to use, but I thought I would pass on the information. Maybe Stiegmeir will come on and directly answer the question of what oil he uses when he does a blower port. What he says would be good enough for me even if it differed from what eaton recommends.
