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.

I didn't say additives don't exist. They ARE put in at the
refinery....all
refineries that adhere to the oil industry's standards, the ones that tell
you it's SJ or CH-4 standard lube oil. All the companies that produce gas
make it so they can all share the commodity as a cartel....oh, oh, can I
say that word?

The advertising is bull**** for the consumers, those idiots who just HAVE
to buy oil with the checkered flag on the can or it's junk.

.....and I'm sure there's plenty of non-standardized commodity floating in
greasy tankers trekking across the oceans as we type.....

....some of those are heading for the Amsoil bottling plant...(c;



I think we are talking two different things here. I am not referring to
motor oil. I am talking about gasoline.
The point the chemist was making was that gas is gas when initially refined
from crude. What differentiates the different brands is the type and amount
of additives they use. Mobil claims to have twice the amount required by
EPA standards. Chevron touts it's "Techron" or whatever. Shell uses
their proprietary "V Power" in the high test. Each of these additives are
required to minimize deposits, but each is a different formulation or
amount.

So, gas may be gas. But the gas you buy at Mobil is different than the gas
you buy at Shell ... or Chevron. That was his point, and I found it
interesting that he recommended rotating the brand every 5k miles to get the
full benefit of each of these different additives.
