I agree with Charlie+ because the oil manufacturers probably have bigger
advertising budgets than their manufacturing budgets because in the end
it's all probably the same stuff.
But how would we know what makes oil coming out of the ground into
something labeled as "the best two stroke oil in the world" on the bottle?

Is SAE30 no detergent oil the same as "mineral oil"?
I thought mineral oil (like the stuff at the pharmacy) is different?

I also thought that up until recently people mixed regular non-detergent
single weight oils into the gasoline at a 30/40/50:1 ratio and it worked.

What are "2T synthetics?"
Answering my own question is Mr. W:
https://en.wikipedia.org/wiki/Two-stroke_oil
2T just means "two stroke" but maybe not as the first sentence was so
confusing that I started wondering if I knew what a two-stroke engine is!
"Unlike a four-stroke engine, whose crankcase is closed except for its
ventilation system, a two-stroke engine uses the crankcase as part of the
induction tract"
Huh?
What is that sentence saying?
I always thought a two stroke was all about the number of strokes, and not
about using the "crankcase as part of the induction tract" (whatever that
means).

I agree they must put some kind of "gloop additive" to get that spread
between cold and hot viscosity which probably isn't good for the engine
(whether it's a 2-stroke or a 4-stroke engine) when it heat carbonizes.
The advertisers only tell you the good stuff but they never tell you the
bad stuff where there must be "more gloop additive" to make the spread
wider and that means more bad carbonization at the same time.

I've seen clear mineral oil sold in the pharmacy for drinking as a
laxative. Is that the same stuff?
