Not bad but not great. I had similar results from SM/GF-4 $.59 Chevron conventional in a Silverado 4.8 at just about the same OCI.


make the inside of your engine oil cap white.
don't use.

How long was this oil in service?
Wear numbers look good but TBN dropped off.

Oil was in for 11 months.
Iron jumped up quite a bit but I don't think it is anything to worry about. New formula is in now and I will see how it holds up.

Your iron has been jumping all over the place!
Copper, lead and aluminum all look really nice with this run!

Anxious to see how the new formula does, keep us posted!
