Synthetic Motor Oil Gets All
New Semantics
(first published in Nov.,
2000 issue of Car and Driver by Patrick Bedard)
Now that the meaning if "is" has gotten so
slippery you need to grab it with both hands, we'd better keep
an eye on longer words, too.
One's already got so squirmy on us- "synthetic," as in synthetic
motor oil.
Most guys know two things about synthetic oils. First, the price
is three to four times that of conventional oils. Second,
they're not real oil, not made from crude.
News flash: Scratch that second part. Now motor oils derived
from crude may be labeled "synthetic." But they still cost over
four bucks a quart.
Bait and switch? That's the obvious conclusion. Except in this
case the advertising ethics people have given their approval.
Here's what happened, according to a detailed account published
in the trade magazine Lubricants World. Late in 1997, Castrol
changed the formula of its Syntec "full synthetic motor oil",
eliminating the polyalphaolefin (PAO) base stock (that's the
"synthetic" part, which makes up about 70% by volume of what's
in the bottle) and replacing it with a "hydroisomerized"
petroleum base stock.
Mobil Oil Corporation, maker of Mobil 1, "Worlds Leading
Synthetic Motor Oil," said no fair and took its complaint to the
National Advertising Division (NAD) of the Council of Better
Business Bureaus. NAD often arbitrates between feuding
advertisers on their conflicting claims.
The notion behind synthetic motor oils as we've known them is an
elegant one. Instead of relying on the cocktail of hydrocarbons
contained in crude oil, why not go into the laboratory and build
the perfect base stock from scratch, molecule by molecule, and
builds it till it gets 10-carbon molecules, then combines three
of those to form PAO. The result is a fluid more stable than the
usual base oils derived from crude. It keeps flowing at low
temperatures. It's more resistant to boiling off, and more
resistant to oxidation, which causes thickening with prolonged
exposure to high temperatures.
Still, there's more than one road to the point B of improved
stability. Petroleum refiners in recent years have learned how
to break apart certain undesirable molecules - wax, for example,
which causes thickening of oil at low temperatures- and
transform them by chemical reaction into helpful molecules.
These new hydroisomerized base oils, in the view of some
industry participants provided properties similar to PAO's but
only cost half as much," Lubricants World reported.
The argument before NAD tiptoed around the obvious- does the
consumer get four bucks' worth of value from each quart of
synthetic oil?- and plunged straight into deep semantics.
Mobil's experts said "synthetic" traditionally meant big
molecules built up from small ones. Castrol's side held out for
a looser description, defining "synthetic" as "the product of an
intended chemical reaction."
What do unbiased sources say? It turns out that the Society of
Automotive Engineers (SAE) and the American Petroleum Institute
(API) both have technical standards covering motor oils, and
both of these organizations in the '90's backed away from their
old definitions of "synthetic," leaving lots of room for new
interpretations.
In the end, NAD decided that the evidence constitutes a
reasonable basis for the claim that Castrol Syntec, as currently
formulated, is a synthetic motor oil, said Lubricants World.
The obvious question now: Has the term "synthetic motor oil"
been opened up to the point that it no longer means anything?
Maybe. But here's a better question: Did synthetic ever mean
what we thought it meant?
"Great oil" is what most guys think it means. "At that price,
it's gotta be great stuff!"
Okay, but how great? Your cars manual tells what motor oil you
should use, and with few exceptions, that description will
consist of only two specifications. One is for viscosity, such
as 10W-30; and the other is for the API service grade, SJ being
the current one for gasoline passenger cars.
The buck-a-quart multi-grades meet these standards, as do the
synthetics.
The synthetics, on the back label, claim compliance with more
standards, but even if you know what they mean, they seem beside
the point for U.S. passenger cars. For example, should you care
about diesels if you drive a gasoline burner? API service CF is
the oldest of the current specs for light-duty diesels; some
synthetics list that one. Synthetics may also list ACEA A1 and
B1, which are European specs roughly equivelant to API gasoline
and diesel specs. The Europeans grad their oils by level of
performance, so that A2 and A3 are tougher specs than A1. Same
for diesels. Usually the date of the spec is omitted, but A1-98
is newer than A1-96.
Completely absent is the one performance claim that would have
some real meaning for all of us- some indication of longer oil
life. (except for AMSOIL
which clearly states 25,000 miles/1-year or 35,000 miles/1-year
for their Severe Service 0W-30 synthetic). Automakers hold
synthetics to the same oil change intervals as conventional
oils. And the oil companies, promise even less. "To give added
protection and life to your engine, change your oil every 3000
miles." This same language appears on the back of both Penzoil
Synthetic and conventional oils. Valvoline synthetic makes a
similar recommendation. (commentary: Since 1972 AMSOIL
is the ONLY synthetic oil manufacturer in the world to guarantee
25,000 mile oil change intervals and utilizing
full PAO synthetic technology exclusively).
Synthetics do get one unambiguous endorsement: Corvettes,
Porsches, Vipers, and all AMG models from Mercedes-Benz come
with Mobil 1 as the factory fill.
Most synthetics mention GM 4718M in their list of claims; that's
the unique spec created by General Motors for Corvette oil. It's
a high-temperature requirement that tolerates less oxidation
(thickening) and volatility (boil-off) on a standard engine test
called Sequence 111E according to engineer Bob Olree of GM
Powertrain. (note: AMSOIL
0W-30 far surpasses GM's 4718M spec).
But don't expect to learn such details on any label (again,
except for AMSOIL
which clearly states test results on the back of every bottle of
Series 2000 0W-30 and 20W-50 synthetic). Mobil 1 at least uses
straight forward declarative sentences. Most of the others read
as though they were written by a lawyer looking for an escape
clause. Why else would the following claim be so rubbery? "Penzoil
Synthetic motor oil is recommended for use in all engines
requiring ILSACGF-1, GF-2, API SJ, SH, or SG, and in engines
requiring oils meeting GM 4718M." Okay, but does it actually
pass those standards?
"Yes" says James Newsom, Penzoil's motor-oil product manager.
Castrol Syntec, on its label, "exceeds" every standard it
mentions. Hmm. Now that the meaning of "is" is in play, I have
to wonder, does Syntec meet those standards as well?
"It does" says Castrol's Julie Ann Oberg. While I have her on
the phone, I ask if there will be a Syntec price reduction now
that the lower-cost base stock has been substituted for the old
synthetic. She says no.
End of article.
Now, after reading that why would anybody in their right mind
want to spend their hard-earned money on Castrol Syntec, Penzoil
Synthetic, Valvoline Synthetic or any of the other "synthetics"
when what your getting is not even a true 100% full PAO
synthetic? Even Mobil 1 Tri-Synthetic uses multiple base-stock
technology by blending other synthetic molecules with the PAO
base-stocks and then they come up with a catchy name of
Tri-Synthetic. Pretty sneaky huh?
AMSOIL moved away
from multiple base-stock technology over 20 years ago!, yet
Mobil makes it sound like their Tri-Synthetic technology is some
new earth-shattering technology. What a joke!
Why not skip all the hype and deception of these other
manufacturers and just use AMSOIL? AMSOIL uses only 100%
full synthetic PAO technology in each and everyone of its motor
oils
and is the undisputed leader in synthetic engine oil technology
as well as the leader in synthetic gear lubes, transmission
fluid, greases, two-cycle oil and many other lubricants and
hydraulic fluids. Today, virtually every other motor oil
manufacturer has recognized the superiority of synthetic
lubricants and has followed the AMSOIL
lead with introductions of "synthetic" motor oils of their own.
They spend millions of dollars advertising their "new" and
"revolutionary" products. Just because they spend
those millions of dollars, they still can not can match AMSOIL
experience and technological know-how. And no one delivers
products like AMSOIL.
Accept no substitutes-
AMSOIL
is the "First in Synthetics."
