95% of the miles are towing my 8000lb 5th wheel, and/or our 4-horse trailer. I only put 6400k miles on the oil in 13 months, and i left the TRD oil filter in during the entire OCI.
OAI in SLC, Utah did the report.
Data indicates no immediate need for maintenance action. Continue to observe the trend and monitor equipment and fluid conditions. TBN is MODERATELY LOW. Lubricant and filter change acknowledged.
NOTE: First number is my PREVIOUS 8400 mile run of SSO, & 2-OEM oil filter changes. Second number will be the current run of HDD w/ TRD oil filter.
*********Wear metals ppm*
IRON--12---11
CHROMIUM--0---0
NICKEL--0---0
ALUMINUM--3---8---This concerns me, as the engine is all aluminum.
COPPER--4---6--???
LEAD--0---0
TIN--0---0
CADMIUM--0---0
SILVER--0---0
TITANIUM--0---0
VANADIUM--0---0
*********Contaminant metals--ppm**
SILICON--14---15--This is high due to use of oiled TRD filter.
SODIUM--10---13
POTASSIUM--0---2
*********Multi source metals ppm**
MOLYBDENUM--10---2 Not much moly in HDD?
ANTIMONY--0---0
MANGANESE--0---0
LITHIUM--0
BORON--22---3--HDD don't have much boron in it?
********Additive metals ppm*
MAGNESIUM--13---10
CALCIUM--3558---3606
BARIUM--0---0
PHOSPHOROUS--583---982
ZINC--676---1177--Wow! Double the zinc. WTH?
DATE sampled--8/14/11
Date received--8/22/11
Unit time--13 months
Lube time--6400 miles
Lube change--yes
Filter change--yes
FUEL--less than .1%
SOOT--less than .1%
WATER--less than .1%
VIS @ 100.C--10.4---11.9---What is virgin HDD?
TAN---not listed
TBN--3.80
I-R OXIDA--41---29---This went down. Nice! Little less towing.
I-R NITRA--22---16---This also went down.
My total miles on the truck are 40k.
I am a little dissapointed in the UOA after using this high end oil, and less miles. Mainly with the Aluminum & TBN numbers. I just replaced this oil and filter using HDD 5w30 and TRD filter, even though toyota recomends a 0w20 or 5w/20 for this motor.
Please comment mainly on the side notes i wrote above.
Thank you.
