I did take it as just that, so seems we agree on that "mildly interesting" data point. One data point that may not mean much if anything with respect to the actual cleaning ability for the reasons I already stated.
If zero other people are claiming it's anything else, then why do you seem to keep trying to argue that this is some meaning definitive data point?

You seem to be putting more into it as a definitive data point than I am, that's all ... must leave it at that, no need to keep going in circles. I'm sure others aren't going to put much credence into one filter cut open from Mobil Clean being ran through a dirty engine that had Valvoline Restore and Protect through it on the previous OCI. It could have show debris in the filter if SuperTech oil was used instead, we just don't know for sure. When more definitive evidence is shown, then Mobil's claim will be more believable. I'm not mad about anything, just calling like I see it. What is BIOG without a bunch of critics, lol ?
