Bought this '08 Ranger 3.0 in September 2020 with 187k miles on it. Decided to see what was in the crankcase. It appears to be 5w-30, but not sure on what oil brand. Any guesses? It has plenty of life left but the wear metals are pretty ugly.
I filled it with Motorcraft Synthetic Blend 5w-20, a Motorcraft oil filter, and ran it 2100 miles and am waiting for the next UOA. Want to see what the metals look like. I'll post that UOA in the next few days when I expect it to be ready. It's now filled with Supertech Full Synth High Mileage 5w-20 and another Motorcraft FL-400S. It appears to be running much smoother, not sure if it's the ST oil or just the fact that it's been flushed a couple of times in a short period of time.
