18 dexos® Engine Test review….
Sequence VIE Fuel Economy test status The 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 labs due 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 labs Changes to the test procedure by the ASTM Surveillance Panel has increased the test duration from 155 hours to 200 hours Additions 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 vehicle Emphasize proper viscosity/vehicle for the installer and end-user Improve process for approving dexos™ suppliers and monitoring dexos™ quality Maintain a long-term sustainable approach to generate revenue for Future test development Future specification development Current test maintenance and monitoring Lubricant quality monitoring End-user and installer education & awareness The Licensing program goals are simple as well; insurance for the end-user, GM, and oil manufacturer/marketer. Sustainability of the specification

28 dexos™ Information Center
Website Information: For manufacturers/licensees How to license For Service Provider Licensed Manufacturers License brands For Vehicle Owner Other useful information Engine oil articles This is a much easier way for the consumer or installer to be sure they are getting the correct product for their vehicle. It is all about the customer….I don’t need to tell you that though……

31 dexos™ Licensing Status

32 Licensing Status All Major Brands in North America are licensed;
ExxonMobil Mobil 1, etc. BP Castrol Castrol Edge, etc. Chevron Havoline Ashland Valvoline Shell Pennzoil Quaker State Helix We 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 remarks Next Generation dexos™ is expected to be completed in 2015 The dexos™ licensing program is self-sustaining and provides a means to fund on-going development conduct targeted oil quality monitoring (bulk & package) increase customer & installer awareness The dexos™ licensing program – continuous improvement We 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 transmission fluid. Failure to use the proper fluid may result in internal damage to the transmission.

35 - DEXRON®-VI DEXRON®-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 requirements Superior oxidation stability, excellent cycling durability, good corrosion prevention, foaming resistance, and controlled frictional properties This fluid also provides good seal compatibility; wear protection, and smoother shifting DEXRON®-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 -COOL DEX -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 -COOL 5 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 copper Protects against winter freeze up and minimizes the chance of summer boil over Compatible with water pump seal materials and minimizes the formation of abrasive dissolved solids Storage stable for at least eight years No silicate dropout or gel formation during use or storage 100% biodegradable in its pure unused form Excellent heat transfer properties Nitrite, borate, phosphate, nitrate, and amine free Outstanding hot surface aluminum protection Superior protection in high operating temperatures

38 DEX -COOL Dilution with conventional antifreeze will reduce extended life benefits. ACDelco recommends that this product not be diluted by more than 10% with conventional coolants .
