The revised Piston Detergency Test Meth-
od was introduced during the SAE Colloquia
in 2014. In 2015, the revised Valve Train Wear
Test and other issues will be introduced, as
follows:
The new valve train wear test has been es-
tablished with new REOs and N04C engine,
which meets the latest Japanese emissions
regulation, as follows:
The new reference oils (Good REO: DV3,
Border REO: DV4)
The new test engine N04C instead
of 4D34T4 (The N04C is the same as the
engine for the Piston Detergency Test)
Tappet Wear instead of CamWear as an
evaluated engine component
The new Valve Train Wear Test was devel-
oped to replace the current test method.
“11.3
μ
mmax ” as the specification for
the tappet wear has been proposed in the
revised JASO M355:2015.
JASO M354:2015 (new Valve Train Wear
Test) and JASO M355:2015 will be issued in
April 2015.
As for other issues, the development of the
Fuel Economy Oil Performance Test Proce-
dure is under discussion through 2017.
Kenji Tomizawa is currently the
manager of the Powertrain
Evaluation & Engineering
Division of Hino Motors. He
has more than 25 years of
experience, especially in durability and
reliability issues of heavy-duty diesel engines
for trucks and buses. He was in charge of the
development of the Hino J-series engines
from 1992 to 1999.
Kenji is a member of the JAMA Engine Oil
sub-committee and the PetroleumAsso-
ciation of Japan (PAJ)/ Japan Automobile
Manufacturers Association (JAMA) Engine Oil
joint sub-committee. In addition, he was the
leader of the Japan Automobile Standards
Organization (JASO) DH-1 promotion team
for Asia from 2004 to 2009.
Since April 2013, he has chaired the JASO
Diesel Engine Oil Standard Revision Task
Force, consisting of PAJ and JAMA. He is also
a member of the JAMA Unregulated Exhaust
Emissions sub-committee and the leader of

group.
ILSACGF-6Update

The auto, oil, and additive industries have
been talking about andworking on ILSACGF-6
for more than four years. The questions still
remain: What will GF-6 look like, andwhen can
we expect it to be introduced? In this presen-
tationwe hope to answer these questions with
strong certainty. The Needs Statement for GF-6
was officially approved by the Auto Oil Advisory
Panel late in 2014. GF-6 is really two new
specifications: one for viscosity grades found
in GF-5 and a second specification to cover
new lower viscosity grades recently added to
the SAE J300 viscosity classification system. A
major undertaking for GF-6 is the updating and
replacement of four engine tests and the devel-
opment of two completely new engine tests.
In addition to all of the test development, GF-6
is beingdevelopedunder a newsystemcalled
theAutoOil Advisory Panel (AOAP), which has
several different processes fromwhat hadbeen
used in earlier ILSACcategory developments.
This presentationwill cover all aspects of the
GF-6 category development startingwith the
Needs Statement through the current timing
for the introduction of this long-awaitednew
passenger car engine oil category.
