Trend of Diesel Engines

• Rapid technical evolution of diesel engines– Performance

– Noise

– Cost

• Longer drain intervals became possible with Direct Injection

• Diesel Particulate Filters (DPFs) require low SAPS oils– ACEA C-sequences

– Low sulphur base oils

• ACEA Sequences first launched in 1996

• 6 revisions

• ACEA 2008 Oil Sequences released in Dec 2008

• Significant updates required formulation and testing

• Implementation by Dec 2009

• ACEA 2007 to be withdrawn by Dec 2010

• ACEA members considering next improvements needed

6

Next Generation Needs in Europe

• Sludge test replacement – MB M111SL test by M271SL

• Test replacements– Valve train wear

– Dispersivity

– Fuel economy?

• Impact of biodiesel on lubricant performance

• Continued development of fuel economy

7

Biofuels

• EU mandate to include “FAME” in transport diesel– FAME often high molecular

weight/low volatility

• “B5” blend adopted in most of Europe – EN590 permits up to 7%

• OEM concerns over impact of biodiesel on lubricant performance– High fuel dilution caused by

late injection

– Cold start performance

– Copper corrosion 8

New MB OM646LA Test

• New test method to evaluate lubricant with biodiesel– CEC TDG-L-104

• Piston deposits, engine sludge wear and oil degradation.

• Using the MB OM646 DE22A engine used in CEC L-099.

• Test Fuel - B15 – 85% Diesel Fuel + 15% FAME

• Test Oil diluted with 7% B100

SAE J300, new and lighter viscosity oils

Group III+ vs Group III base stocks

ILSAC GF-5

New performance level replacing GF-4

Changes versus ILSAC GF-4:New fuel economy engine test: VIDNew method for aged oils low temperature pumping viscosity Stronger engine protection against deposits, emulsion tolerance and seals compatibilityStronger protection of emission control systems

First licensing date is October 1, 2010

API SN and SN Resource Conserving

API SN with Resource Conservingmatches ILSAC GF-5.

API SN with Resource Conserving in the donut tells consumers that the oil meets GF-5 requirements.

• API SN (without Resource Conserving) is intended for the ROW.

• API SN can be used with “C” category oils

16

Future ILSAC and API Categories

Sequence engine parts could be depleted by 2014-2015Consider equivalency tests or new partsTakes about 5 years to develop new testsGM intends/expects to continue support for industry test development even with dexos™ program

API Group established to:Review status of existing Sequence engine testsDetermine what replacement tests are neededConsider improving the process

17

GM dexos™

GM harmonizing engine oil standards

dexos 1™ (gasoline) will start globally with 2011 model year

dexos 2™ (diesel FF/SF and gasoline engines SF) has begun in Europe and Asia

dexos™ specifications combine many aspects of ILSAC GF-5, ACEA A/B and GM proprietary tests

Important base stock note: both dexos™ standards require <13% volatility. Higher quality (high VI) base stocks must be used.

SAE J300 Engine Oil Viscosity Standard

SAE Work Group considering adding new engine oil viscosity grades: SAE “15”, “10” and “5”Lower HTHS viscosities should enable

increased fuel economy (FE).xW-20 gives 33~37% more fuel economy

than xW-30 grades.Looking for more FE gains with lighter grades.

Minimum oil film thickness must be balanced with engine durability.

Lighter grades are feasible with today’s Group III and III+ base stocks

Fix BoV (Base oil Viscosity).

Reduce VM treat to desired HTHS viscosity ranges: 2.3, 2.0, 1.7 cP

Passenger Car Outlook: 2010 to 2015

• SAE 10W-30 demand peaked in 2004.– SAE 5W-30 and 5W-20 grades continue growing

• Expect growth of SAE 0W-20 grade.– Well accepted to improve fuel economy.– Honda and Toyota already recommend

SAE 0W-20 since 2006.– Detroit OEMs slowly transitioning to lighter grades.

• Group III, III+ base stocks will have more demand– More consumers preferring synthetics over

conventional oil for added performance.– Synthetics have 10 % growth rate in US market.– OEMs (GM) driving Group III, III+ demand up with

tighter engine oil volatility limits.
