The posting of these UOA's are always a challenge, this is my 2nd UOA on this vehicle. Blackstone ran this analysis. I was very happy with how PP handled the many short trips this van sees. There were some out of state trips in this run too, but the van is mostly a short tripper. The van was fully warmed up and I did note to the lab that I nearly forgot to pull a sample, so this oil was taken near the end of the drain. I was happy the fuel went down in this run. I put in QSUD 5w20 in for this current oil change, interested to see how that oil does.
Toyota 3.0L V-6 (1MZFE)MAKE/MODEL: OIL TYPE & GRADE: Pennzoil Platinum 5W/20 SM
OIL USE INTERVAL: 6,547 Miles
COMMENTS BRAD: It doesn't look like either the longer oil run or the fact that the sample was taken near the end of the drain altered
your engine's results. Metals are nearly perfectly steady since last time, and that's a great indication that the engine didn't mind
the extra miles on the oil. Chrome and copper have fluctuated by amere 1 ppm each, but that's not enough to worry about the health of this
engine. You shouldn't have any problems running your next oil longer since wear is quite steady and the TBN is still above 1.0 (it read 2.0).
Add 2,000 miles to your next fill. Nice report!
