Zinc was always pretty low.. Seen it as low as 990ppm once.. Jury is still out on the Delo, should be getting first sample back soon!

Which motor are you running, CM-871? I was wondering about the additive package, and I know that these oil companies do change things up. I need to dig into the cummins recommendations for the CM-871 and start shopping oils.
