18 dexos® Engine Test review…. Sequence VIE Fuel Economy test statusThe 2012 LY7 3.6L engine is available to the labs from the central parts distributor.Evaluation of a 0W-16 oil supplied by ASTM TMC has begun. Initial results are positive.Exhaust valve leakage has been experienced at some labsdue to deposit build-up between the valve and seat.Testing has shown that the deposit build-up can be eliminated using a Top-Tier fuel additive package in the fuel.The fuel supplier is now supplying the “new” the fuel to all labsChanges to the test procedure by the ASTM Surveillance Panel has increased the test duration from 155 hours to 200 hoursAdditions to the procedure include tighter specifications around the test stand external oil circuits to reduce Lab to Lab variation.

27 Licensing Program Goals for dexos™ Ensure the right dexos gets into the vehicleEmphasize proper viscosity/vehicle for the installer and end-userImprove process for approving dexos™ suppliers and monitoring dexos™ qualityMaintain a long-term sustainable approach to generate revenue forFuture test developmentFuture specification developmentCurrent test maintenance and monitoringLubricant quality monitoringEnd-user and installer education & awarenessThe Licensing program goals are simple as well; insurance for the end-user, GM, and oil manufacturer/marketer. Sustainability of the specification

32 Licensing Status All Major Brands in North America are licensed; ExxonMobilMobil 1, etc.BP CastrolCastrol Edge, etc.ChevronHavolineAshlandValvolineShellPennzoilQuaker StateHelixWe want the spec to be sustaining and benefit the vehicle owner. We want a level playing field for the oil sellers. We think dexos provides for this.
33 Final remarksNext Generation dexos™ is expected to be completed in 2015The dexos™ licensing program is self-sustaining and provides a means tofund on-going developmentconduct targeted oil quality monitoring (bulk & package)increase customer & installer awarenessThe dexos™ licensing program – continuous improvementWe want the spec to be sustaining and benefit the vehicle owner. We want a level playing field for the oil sellers. We think dexos provides for this.
34 Transmission Fluid Specifications All GM 6 Speed transmissions,use DEXRON® VI transmissionfluid. Failure to use the proper fluidmay result in internal damage tothe transmission.
35 - DEXRON®-VIDEXRON®-VI is a premium quality automatic transmission fluid for use in both passenger cars and light trucks requiring a fluid that meets General Motors DEXRON®-VI specification requirementsSuperior oxidation stability, excellent cycling durability, good corrosion prevention, foaming resistance, and controlled frictional propertiesThis fluid also provides good seal compatibility; wear protection, and smoother shiftingDEXRON®-VI is recommended for application in General Motors vehicle transmissions requiring an DEXRON®-VI, DEXRON®-III (H), DEXRON®-III, DEXRON®-IIE, DEXRON®-II, and DEXRON® automatic transmission fluids.
36 DEX -COOLDEX -COOLANTIFREEZE/COOLANT is a universal engine coolant, which incorporates a patented carb oxylate inhibitor technology. This coolant meets both ASTM D 3306 for automotive service and ASTM D 4985 for heavy-duty diesel service. It is a nitrite-, nitrate-, phosphate-, silicate-, borate and amine-free formulation which uses a patented carboxylate technology to provide maximum protection of the six basic metal alloys found in most heat transfer systems. Since the coolant contains no phosphates or silicates, hard water deposits in the cooling system are almost eliminated. The low level of abrasive dissolved solids in DEX -COOL® ANTIFREEZE/COOLANT results in improved water pump seal life.
37 DEX -COOL5 year or 240,000 km recommended service interval when complete flush and fill is performed.Provides effective, long term corrosion protection for aluminum, brass, cast iron, steel, solder and copperProtects against winter freeze up and minimizes the chance of summer boil overCompatible with water pump seal materials and minimizes the formation of abrasive dissolved solidsStorage stable for at least eight yearsNo silicate dropout or gel formation during use or storage100% biodegradable in its pure unused formExcellent heat transfer propertiesNitrite, borate, phosphate, nitrate, and amine freeOutstanding hot surface aluminum protectionSuperior protection in high operating temperatures
38 DEX -COOLDilution with conventional antifreeze will reduce extended life benefits. ACDelco recommends that this product not be diluted by more than 10% with conventional coolants .
