All that shows is that in the short amount of time you've been running it, in one engine, that it hasn't managed to kill it yet. It doesn't show that it's beneficial or otherwise a good thing.
Seriously though; all this stuff is totally some combination of superstition, voodoo and medieval monks debating the number of angels that can fit on the head of a pin. Without pretty comprehensive experimentation, it's very much one person's opinion vs. another's, and neither have anything conclusive to go by, except what the engine makers have specified for that engine, either in the present or past.
I mean, I could easily say that oil and filters don't really matter, and that you can get a car to nearly 300k on whatever you feel like; after all, my Dad got his 1982 Pontiac Bonneville to 275k using whatever the cheapest quick-lube oil and filters there were. Lots of people here would argue this point, but the fact is that none of us have any proof that thick vs. thin, top vs. bottom bypass valves, etc... actually make any kind of difference in the real world. I mean, they *might* make some difference if you're looking at the entire Federal government fleet and running statistical analyses, but for your average user, it's going to be exceedingly hard to tell.
Might as well hang chicken bones and other magical amulets off your bumper. You'll be able to tell if they work just the same as running 40 weight vs 30 weight.
