Hi I got a 4.0 mustang a few months ago. It came with an orange can fram and black oil. I filled supertech hm synthetic and a st filter. After about 1000 miles I noticed the oil light on a second or two after startup. Oil was pretty dark for 1k. I changed to penzoil platinum hm and a fram ultra. No more oil light. 1000 miles later it is doing it again. Oil level is correct throughout. Is it reasonable to assume the oil light means my filter is clogged with sludge and needs to be changed, or is there some other explination?
I asked my car buddy and he said to ask you guys.
