What's this new
diesel engine oil I'm
hearing about?
You are probably
hearing or reading about
a new API category in
development for heavy
duty diesel engine oils.
This new category,
currently referred to
as Proposed Category
11 (or PC-11), is under
development as you read
this. So what is it and
why are things changing?
In simple terms, when engine technologies
change we often see a new oil category
introduced. This was true in October 2006
when the current API CJ-4 category was
launched. At that time, we needed to work
with new technologies like diesel particulate
filters and the anticipated higher operating
temperatures of some engines.
In the past, changes were typically driven
by reducing particulate matter and NOx
emissions. However the driver for this
round of changes is a little different.
Truck manufacturers are adapting their
technology to develop next-generation
diesel engines to meet emissions,
renewable fuel and fuel economy
standards, as well as to meet CO2 and
other greenhouse gas emissions mandates
due to be introduced in the next few years.
PC-11 will be a significant undertaking for
the industry not just in North America but
also globally. The engine manufacturers
have to respond to new regulation
such as renewable fuels mandates,
on and off-road exhaust emission and
greenhouse gas emission standards. There
are also changes to the hardware and
operating strategies of engines which
can introduce factors such as: increased
power density, increased combustion and
injection pressure, increased in-cylinder
NOx reduction, higher oil temperatures
and wear resistance coatings. As an
industry we must keep pace with such
developments and of course, give the
market the products that it needs.
This is why the American Petroleum
Institute, Shell Lubricants and others in the
industry are looking to provide changes
in the new oils that include improvements
in oxidation stability, aeration benefits,
shear stability, biodiesel compatibility and
scuffing/adhesive wear protection.
This will mean developing new engine
tests and modifying existing engine tests
for deposits and oil. The development of
this specification is well underway and the
planned launch is early 2016. We'll keep
you updated on developments for the new
specification and the next generation of
