5.1 This test method was developed to evaluate the oxidation resistance performance of engine oils in turbocharged and intercooled four-cycle diesel engines equipped with EGR and running on ultra-low sulfur diesel fuel. Obtain results from used oil analysis and component measurements before and after test.5.2 The test method may be used for engine oil specification acceptance when all details of the procedure are followed.1.1 This test method covers an engine test procedure for evaluating diesel engine oils for oxidation performance characteristics in an engine equipped with exhaust gas recirculation and running on ultra-low sulfur diesel fuel.2 This test method is commonly referred to as the Volvo T-13.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.2.1 Exception—Where there is no direct SI equivalent, such as the units for screw threads, National Pipe Threads/diameters, tubing size, and single source supply equipment specifications.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. See Annex A10 for specific safety precautions.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method was developed to evaluate automotive lubricant’s effect on controlling valve-train wear and overall engine wear for overhead camshaft engines with direct acting bucket lifters.5.2 Average intake lifter volume loss is used as a measure of an oil’s ability to prevent valve-train wear.5.3 End-of-test oil iron concentration is used as a measure of an oil’s ability to prevent overall engine wear.NOTE 2: This test method may be used for engine oil specifications such as API SP, and ILSAC GF- 6A, and GF-6B.1.1 This test method measures the ability of an engine crankcase oil to control valve-train wear in spark-ignition engines at low operating temperature conditions. This test method is designed to simulate extended engine cyclic vehicle operation. The Sequence IVB Test Method uses a Toyota 2NR-FE water cooled, 4 cycle, in-line cylinder, 1.5 L engine. The primary result is bucket lifter wear. Secondary results include cam lobe nose wear and measurement of iron (Fe) wear metal concentration in the used engine oil. Other determinations such as fuel dilution of the crankcase oil, non-ferrous wear metal concentrations, total fuel consumption, and total oil consumption, can be useful in the assessment of the validity of the test results.21.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.2.1 Exceptions—Where there is no direct SI equivalent such as pipe fittings, tubing, NPT screw threads/diameters, or single source equipment specified.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific warning statements are provided throughout this document as necessary in each particular section.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
