Here's a Blackstone UOA for a car that sees mostly highway miles, 100 miles per day on weekdays. The filter was a Fram XG7317, changed out with the oil. The vehicle was purchased as a Certified Pre--Owned Honda in May of last year with a little over 6500 miles on it. The CarFax indicated that the original dealer changed out the factory fill at 3800 miles. The first sample is an unknown dealer oil added when they certified the vehicle. This vehicle is equipped with the 2.4 liter L4 "Earth Dreams" engine, which is normally aspirated Direct Injection.
I've used this same oil in two other Hondas, but neither were DI engines. The results were far different in those engines, both showing single digit wear number on Aluminum and Iron. My thoughts are to drop the OCI back to 6K on this round and perhaps switch to a 5w-30 the next time. Any opinion on that?
