This OCI car saw 4 track days with oil temps between 250 and 275F.
Previous 3 UOA's are also with GC.
Redline 5W-30 went in this time.
I am bit concerned about aluminum.
Thinking about it I realize now that I might have made mistake while taking oil sample. I didn't take the drain plug all the way out and I let the oil sip over it.
Given that my oil pan is aluminum that would explain the elevated aluminum...
I don't have oil cooler, and block is cast iron.
but what about sodium, could that come from the dirt on the oil plug?
Last I checked I am not missing any coolant?
Everything else looks normal.
What do you guys make of it?
