Just replace the oil - cheaper first step. I’d go for a heavier oil in my experience - 80W-140 if you’re in a warm climate, 75W-90 if it gets cold where you live. Once the noise is there, chances are you will need to replace something soon but you might get away with it for a while with new lubrication
