UOA of Shell Helix Ultra 0W-40
The oil went in at 115200 km and was changed at 126012 km.
During those 10812 km I added (had to ) about 4.5 liters.
The Fe (Iron) is kinda high.
Why?
Si (Silicon) isn't so my K&N is working good enough for me.
Flashpoint was lowered from 222C (according to Shell) to <160C.
Due to fuel dilution, now with the Krank Vents I hope the oil usage drops AND the piston rings will seal a bit better.
Viscosity at 100C was slightly lower, new was 13.5 cSt and the old oil is 13.2 cSt.
(this full syn oil does not shear down too much)
TBN (Total Base Number) is still high.
Shell doesn't give numbers of virgin oil so I don't know how much I lost.
I'm going to post this UOA on BITOG as well and will share all the comments from the experts.
