You'd pour a low-cost oil that you pay for into bottles of a sponsor's oil that you get for free?

I use Rotella in the gear box and crank case of my CRF 450R and gearbox for my YZ 125. It makes it pretty simple to just buy a gallon jug and be able to use it for both bikes.
Make sure its 15-40. The heavy weight oil doesn't have the extra lubricants that will enhance clutch wear in a wet clutch set up.
Rotella and e85 are the best things to happen to four stroke race motors since Doug Henry.
I also expect that Underalls didn't expect Sterling Marlin to wear their product back in the day (see photo below).
I'm guessing Mark Martin also wasn't popping Viagra every time he got in the car...at least I hope not.
And it is the "Heavy duty diesel oil" rotella T right?
They could just do like Bubba and drink from a Redbull(or Monster or Rockstar) water bottle. I've got no issues with it. They're at least not trying to pull one over on us in that instance. Not that they or anyone cares about what I think. They have to pimp their sponsors. I, as do most, get that. But can they just stop with the hypocrisy already?
Not saying Motul doesn't have other advantages over another oil but that's not one of them.

Strength of character matters to me. For that I make no apologies.
Carefully cut it opep and fold out the paper element to see exactly how your engine is living.
The metal shavings should stay consistent with consistent oil changes.
If a rod is starting to fail you can catch it before it comes undone and destroys the cases.
If you have a magnet epoxied on the drain plug it will collect much of the shavings but cutting open the filter is still a good way to see a problem early.
