2014 Toyota Venza 2GR-FE V6 port injection
Previously did the HPL EC30 20% ratio preparation no UOA submitted.
Sample #2 is the VOA, other BITOG VOA have a near zero ppm of Mo and 500+ ppm of B. The lab re-tested and the Mo is around 100+ ppm. Dave from HPL did an UOA on my batch date code and it came out to be near zero. It remains a mystery.
Sample #3 is a 4K sample taken from the oil filter housing since the filter was changed to do a 10K OCI.
Results:
Other BITOG report a VOA oxidation: 20 Nitration: 8 My UOA is 37 and 14
What does this change in oxidation and nitration mean?
It did shear down from 12.2 to 11.0
The TBN dropped from 9.72 to 6.17
B dropped from 531 ppm to 253 ppm.
Wear metals(Subtraction from VOA): Fe- 4ppm, Al- 2 ppm, Cu- 1 ppm.
Calculated wear metal rate: 1.75 ppm/ 1k mi
Can I do to 10k OCI based on the remaining TBN?
Posting the oil filter later this weekend
Any comments on the data?
