I definitely recommend that if you’ve been running the wrong oil, change to the correct oil and run for a couple thousand miles, then change again. When I bought my N52 with 100k+ miles it looked like there were many things previously ignored, and oil spec was one of them. I changed the oil three times at every 2k miles, the first couple times the oil drained out was incredibly black, then it became golden.
