Nice data plots. It makes sense, as the MicroGreen did about the same as the non-Ultra oil filters on the bigger chunks, yet got out a lot of the smaller stuff.
Ultra beat everybody on the bigger chunks.
We have to decide which is better: Get out more of the big pieces, or more of the smaller dirt. My vote is for getting more of the bigger (14, 21) micron garbage out. Ultra for the win.
Although, if you alternate, one oil change a microgreen (10k miles maybe), then the next an Ultra.... OK I'm thinking way too much.
mmmmmm Im not so sure.
Sayles and Macpherson claim - "Control of particles in the 3-10 micron range had the greatest effect in reducing engine wear."
ISO/ Noria seem to back that as do many external sources.
"The significance of proliferating particles in the 10μm domain is phenomenal. Particles under 10μm cause 3.5 times more wear."
