In November 2005 my Oil analysis reported 0. 02 %WT soot, and the Viscosity was 14. 05 cSt@100 C. with 45,300 miles on the oil!
A year later, November 2006 my oil analysis reports 0. 78 % soot, and the Viscosity is 14. 57 cSt@100C. with 54,800 miles on the oil.
A new SAE 40 Grade oil has to be between 12. 5 cSt and 16. 3 cSt @100C. I would say this Oil is certainly doing very well indeed, and as stated before, I am not concerned about "Soot"!
