- Spring HIll
After recently seeing this UOA about Castrol GTX HM, I can't find any specs anywhere about the spec's for this oil. Does anyone have any? If this oil is THAT good, then I'm up for running the entire winter on this oil, about 7000 miles, and giving it a UOA and posting here. At $10.28 for a 5qt jug, and $1.97 for a ST filter, it seems like a good deal to me.
