OK. I call this the Anti-Bitog oil test. I used the Evil Castrol Syntec 10W30 oil with the Evil Fram X2 (Extended Gaurd) oil filter (full synthetic element). The truck is a mixture of a grocery getter, kid mobile, mixed with some fairly long trips.
A couple of observations.
Look at those low Iron and Copper numbers for the Castrol. I know it is common for Castrol to show lower numbers than Mobil, but it is shocking to see such a dramatic change on your own engine.
My Silicon number is nice and low and I still have the original air filter. When I inspect it, it looks fine. Just slightly darkened. The filter is about 2.5 years old. I don't see any reason to change it.
Where is that Nickel coming from?
Particle count is OK. I was interested because this is a full synthetic element. The numbers are not nearly as good as the recent M1 EP particle count. Insulubles are higher than they were with my last K&N filter.
I have Penzoil Platinum in now, because it was cheap with the Pepboys rebate.
You added about 1000 miles to your oil change for this sample, and most wear improved. That's a very good sign that your Mitsubishi engine has no problems to speak of, and that you're treating it well. The TBN read 2.8, still showing some (not a lot) active additive left in the oil. The particle count read 17/13, clean for an engine oil. The number of particles present >=2 micron: 1969. >=5: 729. >=10: 202. >=15: 78. >=25: 18. >=50: 1. >=100: 0. We think your oil filtration system is working well and the oil could be run longer next time. Try 8000 miles.
