We believe that low and, more importantly, consistent engine friction can contribute to more reliable and repeatable brake numbers. This in turn gives more weight to using brake data as a “check and balance” measurement, backing up indicated data.
Low ring/piston/bore wear is important from a blow bye perspective, directly effecting indicated numbers.
Oil particulates have been shown to effect many types of combustion.
Nice to have friction, blow bye, and oil consumption the same at the end of three months of testing as in the beginning.
