What the oil analysis DOES NOT show you is how much of the additive package remains. It also does not show non metallic particulate.

There are a number of important additives in oil that get "used up." The one that is used up quickest is the one that allows moisture to be absorbed into the oil. Additionally there is the viscosity index improver that basically consists of staff shaped elements that curl up and extend depending upon temperature. In hot weather operation, these wear out quickly.

Additionally there is various grit that does not show up in the analysis because it is not metallic. It also is too small to be trapped by a filter.

If you are happy with 60% or 70%, maybe 80% if you're lucky, of maximum engine life, then your filter addition and 10,000 mile oil changes will work well. If you are shooting for MAXIMUM engine life, change it hot and change it often IMHO.

Also, any 616 or 617 engine that goes 10,000 miles without adding oil belongs in a museum.

Have a great day,
