Blackstone Oil Analysis - 10,000 miles on Honda Genuine Full Synthetic 5w30

This analysis was done shortly after reaching 10,000 miles on the oil, or 10 months. It was last changed at 50,000 in February and changed recently in December. Total mileage on the car is about 60,500 miles. No oil was added during this period as I wasn't losing any during my routine checks. The oil filter used was the TSX Purolator PureOne.

As you can see from the results, the oil has plenty of life left in it with Blackstone recommending 12,000 miles next time and checking that. At my current rate, that would push me to full year intervals. My only concern is of course the bearing wear, though that isn't attributed to the oil itself.

This December when I changed the oil I again used this oil, only this time I used the NAPA Platinum oil filter designed for synthetic oil. I'll change it out at 12,000 and post my results at that time.

An oil change is the cheapest maintenance that will have direct long term effects on engine life. Irregardless of anything, engines wear and oil breaks down. I'd rather change it at 5k and know I'm good to go, than run for extended intervals and risk increased wear on my internals... But that's just me, I'm not a tightwad.... Hondas maintenance recommendations are influenced by too many outside opinions (I worked for Honda, and like any manufacturer, when you push oil changes out to 10k miles, it lowers the estimated services costs and overall ownership costs of a vehicle...when you're selling it brand new. Similarly, manufacturers are switching to 0w20, mainly to meet new EPA standards... Not because it benefits the consumer by extending engine life.)

Everyone makes their own decisions, but every vehicle I've ever worked on with over 200k miles had regular oil changes done at least every 5k miles.
I just traded in a 2002 Ford F-150 SuperCrew 4x4 5.4L Triton V8 gas, 285,761 miles. I did an oil change using Mobile1 & NAPA Platinum filter the day I drove it home, and ONCE a YEAR thereafter... pulled a 36ft Travel Trailer everywhere, beat the shit outta that truck I loved, 4x4'd in mud, mountains, woods and rivers! With 38" BFG's and lifted 12" I only got about 10-12 mpg in the city, but on the highway, averaged 32-34 mpg. Had to replace the Trans around 182,000 miles, but NEVER had any issues with the engine.
