First column is my most recent oci with Valvoline Synpower 5w-20. Miles on oil 6,000. Oil used from 98,000-104,000. Blackstone lab.
Second column is Mobil 1 5w-20 from June. Miles on oil 7,630. Oil used from 90,235 - 97,865. Butler lab
Third column is universal averages from Blackstone.
Aluminum 2 / 2 / 3
Chromium 1 / 0 / 1
Iron 4 / 8 / 8
Copper 2 / 3 / 4
Lead 2 / 9 / 6

Manganese 0 / 0 / 1

Sodium 7 / 31 / 11
Calcium 2366 / 1587 / 2210
Magnesium 8 / 12 / 120
Phosphorus 658 / 448 / 746
Zinc 762 / 579 / 912
Barium 0 / 0 / 0
antimony 0 / 2 / ?
fuel --- / negative
antifreeze neg / neg
water neg / neg
insoluables short / unknown
TBN 2.6 / 6.0
No make-up oil was used for either of these.
First column SUS viscosity @ 210f 51.6
Second column Visc cSt 100c 9.0
Blackstone comments: Some types of Honda engines tend to shear down the VI improve in the additive group, causing the viscosity to drop. The low viscosity in this sample wasn't caused by any gas, moisture, or anti-freeze in the oil. Universal averages show typical wear metals for an oil from this type engine after about 5,495 miles run on the oil. Your oil was in use just longer, and we found wear generally better than average levels. Air and oil filtration appear normal. The oil could have stayed in use longer, Try 6,500 miles for the next sample. We will monitor the wear for you
I just called up blackstone and spoke with them about the fuel %, flashpoint, and insoluables. They said i didn't send enough oil for them to perform these tests, thats why it says short, and -.
Also, i ran this oci shorter than normal on purpose. The car was also driven harder than normal during this oci.
By accident blackstone left the tbn off of the report, so i'll update the image file when they send me the new one.
