Here is the #1 UOA results for Lubrication Engineers LE8531, 5w30 Monolec Tetra-Syn
VOA numbers are the first set, the sodium I hope is from a previous diet of Valvoline SynPower, I am not loosing any coolant, opinions on the copper? Experts please comment - what do you think? Filter was a Pure One PL 10241, 45,113 miles on engine & truck, 5,072 miles on OCI.
Lab comment - "Base Number is SIGNIFICANTLY LOW. Sodium is at a MINOR LEVEL; Sodium sources: coolant (antifreeze), lube additive or supplement, and/or environmental contaminant. Lubricant and filter change acknowledged."
