As for gasoline .... according to this chemist, it's all in the
additives. Furthermore, he points out that crude from which gasoline
is refined varies, even within a specific brand.


What "additives"? Who adds it after the trucker, who doesn't have any way
to add anything and doesn't carry anything to add it with, picks it up?
The marina doesn't add anything. I've watched 'em. They did add a stick
to see how deep it was in the tank. There wasn't anything on the stick
except some water detector paste on the bottom that turns color if there's
water in the tank.



FWIW, the author of the article in the link I provided claims to be an
employee of a major oil company. He says he is a chemist who works on their
gasoline "additives". If he is legit ... why would an oil company have a
PhD on their payroll if he didn't do anything?

If you read the article, he acknowledges that gas is gas. Actually he says
gas is not always refined from the same quality or type of crude, even
within a certain "brand". He claims that what makes Shell gas ... Shell, or
Mobil gas .... Mobil, or Chevron gas .... Chevron .... is the type of
octane enhancing and deposit cleaning additives used by the various
companies.
