Lucas Oil Additive Test

I think there are to many variables when testing these oils, I wont lie Ive used Lucas in engines that smoke and it helps clear that up.
Could this demonstration be considered a true test? i think this one is smoke and mirrors, all it is showing is how well oil sticks to gears and my first thoughts were the oil was sticking to itself not releasing its lube qualities. a good thing to consider is that most overhead cammed engines are lubed through the oil pump pressure and how long would it take to pull that sluggush oil to the top especially on a minus 10 degree day, and again thats why i said there are to many variables.
a good test would be in these 200 ton dumps that run 23 out of the 24 hour day for months, lucas side by side with normal oil, same conditions and maintanance and then tear down the engine and compare
Nothing sticks out in my mind that lucas made my car go 200000 miles, but normal oil changes did and Ive pulled the valve covers on the engine and with normal oils and maintanace the cams look like the day they came from the factory
