You may have just gotten a little extra metal buildup in the system. This short oil change did wonders washing all that stuff out ofthe block, so things are looking really good at this point. Universal averages show typical wear levels for this type of engine aer about 5,800 miles on the oil. You can probably go longer than that we suggest 6,500 miles next time. As long as wear stays reasonable we'll suggest even longer thereaer. The TBN shows the oil is chock-full of active additive, and no contamination was found. Nice report!
