Are premium synthetic motor oils worth the extra
expense for your vehicle? The consensus—the
general agreement among automotive experts—is
that premium synthetic oils are superior
lubricants. In this article, the synthetic oils
discussed are specifically identified as premium
synthetic oils because, like with every class of
consumer product, and there are varying levels
of quality. Simply labeling an engine oil as
“synthetic” is not a reliable indicator of
quality, as the overall formulation of the oil
is the most important factor in the quality and
efficacy of the lubricant. A well-formulated
conventional engine oil can outperform a poorly
formulated “synthetic” engine oil. With that
said, beginning the formulation of a motor oil
with high quality synthetic base stocks does
allow for a superior product compared to an
equal quality level conventional motor oil.
Motor oils, and most lubricants in general, are
composed of base oils and additives. Discussion
of “synthetic” or “conventional” relates only to
the base oils in the lubricant. Conventional
base oils are made from crude oil/petroleum and
occasionally re-refine used oil. Synthetic base
oils are made from petroleum, hydrocarbon gases,
and alcohols. Ultimately, all lubricant base
oils are hydrocarbon molecules; the processes by
which the synthetic base oils are made is what
sets them apart from conventional base oils.
The advantages of synthetic base oils are thanks
to the extreme cleanliness and consistency of
the molecular structure achieved in the
processing. Conventional base oils are typically
only lightly refined, with not all of the
inherent impurities (waxes, sulfur, etc.)
removed from the petroleum. Instead of being
simply refined, the crude for synthetic oil is
engineered to produce a uniform molecular
structure that offers superior lubrication.
Finally, proprietary additives are introduced to
make full synthetic oil even better.
Premium full synthetic motor oil costs more
because synthetic oil costs more to make. The
high quality synthetic base oils and
state-of-the-art additives used are typically
much more expensive than the materials used in
standard lubricants. However, with lubricants
you do get what you pay for, in that a
well-formulated synthetic oil that uses
high-quality, synthetic base oils and
high-quality additives, provides additional
benefits for the higher purchase price.
Keep these facts in mind when you take your car
or truck in for its next scheduled oil change.
Advantages of Premium Synthetic Motor Oil
Better High-Temperature Performance.
Premium synthetic engine oils are less volatile,
so they maintain viscosity better than
conventional oils and lower quality synthetic
Better Low-Temperature Performance.
The high-quality synthetic base oils used in
premium synthetic lubricants provide better
natural cold flow, so the oil flows and
lubricates better before reaching full operating
Because of the consistent molecular structure
and purity of the base oil, premium synthetic
engine oils are more stable, better resist
oxidation (aging), and produce fewer deposits.
In fact, some premium synthetic oils like Royal
Purple actually remove existing engine deposits.
Because of the superior cold flow, greater
lubricity, and cleaner operation of the engine,
premium synthetic engine oils can also
contribute to greater fuel economy.
Fewer Oil Changes.
Do you change your oil every 3,000 miles? Every
6,000 miles? Those are the most common intervals
for U.S. cars and trucks. With Royal Purple full
synthetic motor oil, feel free to change your
oil every 12,000 miles, or 12 months (whichever
comes first). That’s 16–50 fewer oil changes
over the life of a car or truck that reaches
Royal Purple is one of a few commonly available
premium synthetic engine oils, so it provides
the inherent advantages listed above, but Royal
Purple synthetic oils go beyond that, as well.
Because of the advanced, proprietary Synerlec®
additive technology, Royal Purple synthetic oils
containing Synerlec outperform any other
lubricant, including other premium synthetic
Synerlec additive technology increases the oil
film strength to 3 – 4 times that of any oil of
comparable viscosity. This reduces
metal-to-metal contact, thereby greatly reducing
short- and long-term wear, as well as damage
that occurs at cold start. This incredible film
strength along with increased oxidation
resistance provides a higher level of protection
even when traffic and conditions are at their
