I just changed the oil… I used Rayol purple 20/50. Rayol purple filter.
The oil pressure hot now is – 45/50 idl and 70/75 at 3000rpms.
Maybe she just wanted a oil change….. Come to think of it. I may have put synthetic oil in it a time or two….I know i put motorcraft part synthetic the other day bc It was the cheapest. Maybe that was the problem.
