I guess you don't understand the scientific method.I guess you didn't watch the video
I don't see where he includes multiple engines for a control group and multiple engines for the test group.
Also if your oil analysis ppm are "high" - what does that mean? Does your engine self destruct? Does it use more oil? Does it make more/less HP? No, it means you post online about it and buy more expensive oil and/or change it more often. But why? To what end? Why not change every 100 miles?
Again, where is scientific studies showing that early oil changes make a lick of difference for passenger vehicles?
