GM has recently introduced the sec-
ond-generation dexos1™ engine oil spec-
ification. It builds in several performance
improvements, especially around low-speed
pre-ignition (LSPI) and fuel economy. GM
has introduced a vehicle fuel economy test
into the second-generation specification in
order to enhance fuel economy perfor-
mance in future oils. This is a new concept
for North American engine oil specifications.
However, it is very common in European en-
gine oil specifications. The challenge of the
new specification is to have formulations
that provide top-notch low-speed pre-igni-
tion and fuel economy performance without
compromising other properties such as ox-
idation, deposit and sludge control, as well
as wear performance. Lastly, GM sees this
new specification as a benefit to the industry
by allowing additive and oil companies to
get a start in formulating around LSPI and
fuel economy and to prepare themselves for
the upcoming proposed ILSAC GF-6 engine
oil specification.

With the impending development of GF-6,
the newest generation of engine oil, a new
standardised oil oxidation and deposit test was
developed using a Chrysler 3.6 L Pentastar
engine. The performance requirements
and approval for passenger car light-duty
gasoline engine oil categories are set by the
International Lubricants Standardization and
Approval Committee (ILSAC) and the American
Petroleum Institute (API) using standardised
testing protocols developed under the
guidance of ASTM International. This paper
describes the development of a newASTM
Chrysler Oxidation and Deposit Test that will
be used to evaluate lubricants performance for
oil thickening and viscosity increase as well as
piston deposits.
Kaustav Sinha is currently
Project Manager withChevron
Oronite leading theGF-6 and
Dexos1™ developments in the
automotive engine oil group.
Prior to joiningChevronOronite, heworked for
DowChemical, InfineumUSALP and FordR&D,
all in the area of automotive lubricants and
tribology. He has led andmanaged several
projects ranging from lubricant product
research anddevelopment, strategy, business
development, laboratory expansion and
intellectual property.
