My brand new Honda Civic EX-L. 40 mi each way to work, mostly highway miles. Average 1 hour each way to work. South Texas so higher than average temperatures. Factory Honda fill 0W-20, 6,350 oil miles, 6,350 vehicle miles.
I changed it at 40%. Even though there was a good amount of TBN left I'm glad I did because of the other levels.
I changed it and put in Mobil 1 Extended Performance 0W-20 with a Mobil 1 oil filter. (Auto Zone had a sale, $45 for 5 qts and the filter)
I will run the Mobil 1 until the OLM is 20%, and do another UOA with TBN. If the results of that look good, then I'll stick with this combo and 20% OLM.
There is some extra metal here compared to universal averages, but that's just from new parts wearing in and is perfectly normal for factory oil. Silicon is from harmless factory sealers washing out and that's normal too. Universal averages show typical wear levels for this type of engine after about 6,800 miles on the oil. There's a trace of fuel here, but that's probably just from normal use and isn't anything to worry about. The TBN is 4.2, showing plenty of active additive left.
Check back at around 20% on the OLM.
