Designation:D 5844 98An American National StandardStandard Test Method forEvaluation of Automotive Engine Oils for Inhibition ofRusting(Sequence IID)1This standard is issued under the fixed designation D 5844;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 covers a laboratory engine test proce-dure,utilizing a 1977 350 in.3displacement(5.7 L)OldsmobileV-8 engine.The procedure,using leaded gasoline,evaluatesthe rust inhibition characteristics of engine oils.The testmethod was designed to relate particularly to short-trip serviceunder typical winter conditions in the upper midwestern UnitedStates.The procedure has been correlated with vehicles,usingleaded gasoline,in that type of service and prior to 1978,2particularly with regard to rusting.It is one of the test methodsrequired to evaluate oils intended to satisfy the API SJcategory.31.2 Information Letters are published occasionally by theASTM Test Monitoring Center4(see Appendix X1)to updatethe test method.Copies of these letters can be obtained bywriting the Center.1.3 The method may not be applicable for the evaluation ofengine oils if unleaded gasoline is used.1.4 The values stated in inch-pound units are to be regardedas the standard.The values given in parentheses are forinformation only.1.5 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.See Note 1,Note 2,Note 3,Note 6,Note 7,Note 8,Note 9,Note 10,Note 11,Note14,and Note 15.1.6 A Table of Contents follows:SectionScope1Referenced Documents2Terminology3Summary of Test Method4Significance and Use5ApparatusOverview6Reagents and Materials7Preparation of Apparatus8Laboratory Ambient Condition8.1Assembling the Test Engine8.2General Information8.2.1Cleaning Engine Parts8.2.2Cylinder BlockPreparation8.2.3Main BearingsInstallation8.2.4PistonsFitting and Numbering8.2.5Piston Ring End GapsAdjustment8.2.6Connecting Rod and Piston AssembliesInstallation8.2.7Connecting Rod BearingsInstallation8.2.8CamshaftInstallation8.2.9Harmonic Balancer and Oil SlingerInstallation8.2.10Engine Front Cover and SealInstallation8.2.11Timing Mark IndicatorModification8.2.12Oil PumpInstallation8.2.13Dipstick TubeInstallation8.2.14Oil PanModification8.2.15Cylinder HeadPreparation8.2.16Rocker Arm DeflectorsInstallation8.2.17Valve LiftersInstallation8.2.18PushrodsInstallation8.2.19Intake ManifoldsInstallation8.2.20Rocker Covers,Spacers and GasketsInstallation8.2.21Water Inlet AdapterInstallation8.2.22Breather TubeInstallation8.2.23Thermostat HousingInstallation8.2.24Fuel Pump and EccentricInstallation8.2.25Oil Filter HousingInstallation8.2.26Oil Sample LineInstallation8.2.27Ignition SystemInstallation8.2.28CarburetorInstallation8.2.29Accessory Drive UnitsDelete8.2.30Exhaust ManifoldsInstallation8.2.31Engine Flywheel and GuardsInstallation8.2.32Special PartsSources8.2.33Engine Coolant SystemPressure Checking8.2.34Installation of the Assembled Engine on a Test Stand8.3Engine DynamometerInstallation8.4Measurement and Control of Operating Conditions9Temperature MeasurementsGeneral Information9.1.1Thermocouple Locations9.1.2Air-to-Fuel Ratio9.2Carburetor Air Supply Humidity9.3Exhaust and Exhaust Back Pressure9.4Blowby9.51This test method is under the jurisdiction of ASTM Committee D-2 onPetroleum Products and Lubricants and is the direct responsibility of SubcommitteeD02.B0.01 on Passenger Car Engine Oils.Current edition approved April 10,1998.Published November 1998.Originally published as D 5844 95.Last previous edition D 5844 97.2Available from ASTM in Special Technical Publication(STP)3151(Part 1).Also available from the Society of Automotive Engineers(SAE)as Technical PaperNo.780931.The SAE address is 400 Commonwealth Drive,Warrendale,PA15096.3Information available from the American Petroleum Institute(API)in itspublication API1509 Engine Oil Licensing and Certification System.The APIaddress is 1220 L Street,NW,Washington,DC 20005.4Until the next revision of this test method,the ASTM Test Monitoring Centerwill update changes in the test method by means of Information Letters;these canbe obtained from theASTM Test Monitoring Center,6555 PennAve.,Pittsburgh,PA15206-4489.Attention:Administrator.This edition incorporates revisions in allInformation Letters through No.971.1AMERICAN SOCIETY FOR TESTING AND MATERIALS100 Barr Harbor Dr.,West Conshohocken,PA 19428Reprinted from the Annual Book of ASTM Standards.Copyright ASTMSectionCrankcase Pressure9.6Oil Pressure at the Oil Pump Outlet9.7Oil Pressure at the Engine Oil Filter9.8Carburetor Inlet Air Pr
