Performance without compromise.
M
odern engines require an
increasingly sophisticated
lubricant. The latest designs,
engineered to be more efficient,
reliable, and environmentally friendly,
increase the stress on the oil in terms of wear
protection and cleanliness and present new
performance demands such as aeration and
pre-ignition protection that push formulators
to develop new technology solutions.
The new GM dexos™1 specification sets the
performance standard for modern engines
and is the industry benchmark for premium
quality oils for all engines. The new standard
will be official from 1st September 2021
globally. Marketers wishing to introduce a
product that meets the new standard must
follow GM licensing rules and requirements

to use the official dexos™1 logo on their
products.
In designing the new specification, GM
engineers identified the need to maintain
and enhance performance in several areas to
reduce warranty concerns. New tests have
been developed to challenge the performance
of the oil in three specific areas: wear (GM
MTM), pre-ignition protection (GM
SPI3), and fuel economy (GM OEE). GM
have set the standard in these new tests to
ensure significantly higher performance
than previous versions of the dexos™1
specification. In addition, performance is
enhanced or maintained when it comes to
oxidation, piston cleanliness, sludge, aeration,
corrosion, and turbocharger protection. The
result is a new premium quality standard
that demands the latest in lubricant
technology and performance.Understanding
these new performance demands is the
lubricant formulator's role. Understanding
the evolutionary path that engineers have
followed to enhance the internal combustion
engine's efficiency in modern designs provides
the key insight for formulators to design
the optimum lubricant for those engines,
performance without compromise.
