Nice report for sure. I guessy if one got picky you could complain about the insolubles and lead. But I'd take it.

400 flash=nice.
 
i'm not that picky any more.

insolubles have always been in that range (even after some autorx), so i just live with it.
 
Looks good!

On my UOAs with Syntec blend (and any other blends/dino) the oil thins out to a low or below 30 wt and folks say it due to the timing chain in my toyota engine...

No chain here and some thinning.

I'm not concerned with this but others are. The wear metals and flash are more important to me..

Thanks for posting!

I wonder if the oil had stayed in grade would the lead (7ppm) come down?

I see you had lead of 2 in previous UOAs.

outside of the mobil1 i used to use, my viscosity has always been slightly out of grade.

i usually had higher iron with the mobil1, so i started trying out other oils.
