That's a really nice TBN figure.......

TBN almost seems unnatural after 5k miles of use. At the rate of decline, this oil is good for 25,000 miles. Hahahaha.

I thought I'd add this for anyone who is newer at looking at oil results. Generally speaking, the higher an oil's total base number (TBN), the better its ability to neutralize contaminants such as combustion by-products and acidic materials. TBN is a measure of (alkaline) additives in the oil. SF

Good metal wear rates. Oil is serviceable with rather high residual TBN, though with a tad of fuel dilution. OCi could be further extended I suppose.

Those are all great numbers!

I thought it was high, so I started looking for info on what it started at, as far as I could find 0W-40 EF starts at 12.6 TBN. Then a measure of 8 didn't seem that high for 5100 miles and suggested 15000 mile life span.

A very average looking report with the exception of the elevated lead, which was more than double the universal average in that sample. I'd try another brand of oil for the next OCI
