I used the following disclaimer on my oil color post today based on drama with the PF posts requiring disclaimers b/c clearly, one could infer that I am saying/implying lighter colored oil at the same OCI is "better".it could be inferred ranking.
HPL cleans, while the others so far dont.
I understand what you are doing and it is a fun exercise, but some members here get bent out of shape when people do these home "exercises".
Disclaimer: obviously this means nothing, is not scientific, no conclusions can be drawn from the color differences, and I'm not telling you which oil is better performing based on color. It's just something I did b/c I was curious and it's fun. End comms.
