Only thing I am worried about is the Silicon though it did go down from the last UOA(22). The oil thickened a bit probably because of Tufoil. I usually get a numerical value for soot/solids but it was N/A this time probably due to PTFE in Tufoil. I have 3 other UOA's on this engine here on BITOG. Any questions/comments are welcome.
Thanks,
Deven.
P.S. Currently have PP 5w30 with 4oz Tufoil and Fram Extended Guard Oil Filter.
