Designation:D 5302 01An American National StandardStandard Test Method forEvaluation of Automotive Engine Oils for Inhibition ofDeposit Formation and Wear in a Spark-Ignition InternalCombustion Engine Fueled with Gasoline and OperatedUnder Low-Temperature,Light-Duty Conditions1This standard is issued under the fixed designation D 5302;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method is commonly referred to as the Se-quence VE test2and has been correlated with vehicles used instop-and-go service prior to 1988,particularly with regard tosludge and varnish formation and valve train wear.3It is one ofthe test methods required to evaluate oils intended to satisfy theAPI SJ performance category.1.2 The values stated in either inch-pound units or SI unitsare to be regarded separately as the standard.Within the text,the SI units are shown in parentheses when combined withinch-pound units.Some of the figures and forms have identicalnumerical designations,but with the letter M following thenumerical designation:these are alternative figures and formsthat contain SI units.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.Specific precau-tionary statements are given in 7.7,7.8.9.6,7.8.13,7.10.2,7.10.3.2(c),8.3.4.2,8.4.4.3,8.4.5.2,9.3.4.4,9.6.1.2,12.1.1.5,12.1.4.5,12.2.1,12.2.1.5,Fig.A3.6,and Annex A8.1.4 Table of Contents:SectionScope1Referenced Documents2Terminology3Summary of Test Method4Significance and Use5ApparatusGeneral Description6ApparatusThe Test Engine7Sequence VE Test Engine Parts Kit7.1Required New Engine Parts7.2Reusable Engine Parts7.3Specially Fabricated Engine Parts7.4Special Engine Measurement and Assembly Equipment7.5Miscellaneous Engine Components-Preparation7.6Solvents and Cleansers Required7.7Assembling the Test EnginePreparations7.8Assembling the Test EngineInstallations7.9Engine Installation on the Test Stand7.10Engine FluidsSupply/Discharge Systems8Intake Air8.1Fuel8.2Engine Oil8.3Coolants8.4Measurement Instrumentation9Temperatures9.1Pressures9.2Flow Rates9.3Fuel Consumption9.4Speed and Load9.5Exhaust Gas9.6Miscellaneous Laboratory Equipment10Test Stand Calibration11Verification11.1Unacceptable Calibration Tests11.2Test Stand Modifications11.3Reference Oil Accountability11.4Test Numbering System11.5Procedure12Pre-Test Procedure12.1Engine Operating Procedure12.2Periodic Measurements and Functions12.3Special Maintenance Procedures12.4Diagnostic Data Review12.5End of Test Procedure12.6Interpretation of Results13Parts Rating AreaEnvironment13.1Sludge Ratings13.2Varnish Ratings13.3Clogging13.4Sticking13.5Wear Measurements13.6Assessment of Test Validity14Average Exhaust Gas NOXLevels14.2Used Oil Analyses14.3Blowby Flow Rate14.4Intake Manifold Vacuum14.51This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products and Lubricants and is the direct responsibility of SubcommitteeD02.B0.01 on Passenger Car Engine Oils.Current edition approved June 10,2001.Published July 2001.Originallypublished as D 5302 95.Last previous edition D 5302 00a.2Until the next revision of this test method,the ASTM Test Monitoring Centerwill update changes in the test method by means of information letters.Informationletters may be obtained from theASTM Test Monitoring Center,6555 PennAvenue,Pittsburgh,PA 15206-4489.Attention:Administrator.This edition incorporatesrevisions in all Information Letters through No.00-1.3ASTM Research Report RR:D02:1226.Sequence VE Report to the Subcom-mittee D02.B Oil Classification Panel,contains the field-laboratory correlationinformation and the initial laboratory test precision data.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.Fuel Consumption Rate14.6Oil Consumption14.7Report15Report Format15.1Special Forms for Automated Data Acquisition15.2Standard Report15.3Calibration Test Report15.4Precision and Bias16Precision16.1Bias16.2ANNEXESSpecial Service Tools for the Test EngineA1External Oil Heat Exchanger Cleaning TechniqueA2Detailed Specifications and Photographs of ApparatusA3Engine Part Number ListingA4Operational Data Log SheetsA5Rating WorksheetsA6Final Report Forms and PhotographsA7Safety PrecautionsA8Automatic Data AcquisitionA9Oakite 811 Monitoring ProgramA10Test PrecisionReference OilsA11Control Chart Technique for Severity AdjustmentA12Statistical Equations for Mean and Standard DeviationA13Data DictionaryA14One-half Millimetre Oversize Piston ModificationsA15Required Inspections and Operations for Reu
