Engine Tests dexos1 ® - Next Gen Specification Highlights Combination of CEC, ASTM, and GM engine tests CEC/ACEA Tests: M-271 Sludge (M271 Evo) M-111 Fuel Economy (if available) ASTM/ILSAC Tests: Sequence VH Sequence VID/VIE Sequence VIII GM Tests: OP-2 Aeration GMOD Turbo Charger Deposit Test Wear Test Stochastic Pre-Ignition Vehicle Fuel Economy Test
dexos ® Engine Test review…. 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. Sequence VIE Fuel Economy test status
dexos ® Engine Test review…. LSX V8 based Twenty-four tests completed Current testing (ongoing) Piston and ring hardware verification progressing favorably Finalize test stand hardware Next steps Finalize test cycle conditions Evaluate GMOD reference oil performance GMOD LTMS guidelines reviewed by TMC. Test procedure and test stand setup kit expected to be available Q Precision matrix expected to start Q GM Oxidation and Deposit test status
dexos ® Engine Test review… L V8 LC9 engine 20 GM Aeration tests completed at SwRI Aeration test candidate oils are provided by several additive companies 20 oils have been tested 9 oils are ready to evaluate for viscosity grade and antifoam effects Current testing VGRA (a wide range including low viscosity 0W-16) Test stand hardware, test cycle conditions and procedure to be finalized Q Precision matrix expected to start in Q tests ( 4 for good oil and 4 for bad oil) per engine Next steps Evaluate GM’s dexos1 and dexos2 oils performance Establish appropriate aeration targets GM Aeration test status
dexos ® Engine Test review…. 1.4L engine 24 GMTC tests completed at IAR 5 GMTC Test stands Flush and run new turbocharger start/stop evaluation GMTC reference oils under evaluation Current Testing Test duration reduction Next Steps Finalize test cycle set points, durations and acceptance parameters Test procedure expected to be available early Q Precision matrix expected to start Q GM Turbocharger Deposit test status

dexos™ Licensing Status
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
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
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.
- 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.
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.
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
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.
