There. I think that's everything. Needless to say, I'm pleased with the report. Most of my wear numbers still seem to be trending slightly downward--if that's possible. I changed labs, oil filter brands (formerly M1-110), and I drive slightly more highway miles (~30% highway miles) on this interval, so I didn't include the last interval for a reference.
This is my first report with WearCheck. I'm somewhat dismayed that they didn't report oxi, nit, or TBN. I talked with the lab tech this morning about this and he insists that TAN is a much better indicator for gasoline engines than TBN, and he says that oxi and nit aren't tested unless there's a suspected problem. He says those two tests aren't very reliable for synthetic oils.
