Castrol Syntec 10W30 Mitsu Montero 3.8L V6 7614 Mi Fram X2 Particle Count

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.

Blackstone Comments: 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.

I agree with Pablo. Nickel would be from an alloy. If I had to bet money on one of my guesses I would guess its coming from the camshaft. The nickel reading is low. I would be more concerned about a tin reading then nickel.

Winston can you list out more info about particle count you got with other oil / filter / mileage combinations? Did you use M1 EP oil with K&N filter combo. on your last run? Very intersting. Thanks for spending the bucks to do the particle count.

Oops forgot to put in the dates. The old Mobil 1 sample date was May 12, 2005. The oil was in about 8 months old. The latest sample was taken on Feb. 1, 2006. So that is about 8.5 months. As far as the last filter (K&N) I did not do a particle count. The last oil was the regular M1, not the EP. I think it was SL. The M1 EP particle count that I was referring to was done by someone else on a different engine. So, it does not compare directly, but I think it still is usefull data. Here is a thread with a bunch of particle counts. Particle Count Thread
