5.1 Test Method—It was determined through field testing that intake valve deposits could adversely affect the driveability of certain automobiles.7 Southwest Research Institute and BMW of North America (BMW NA) jointly conducted testing to develop this test method to determine an unleaded automotive spark-ignition engine fuel's propensity to form intake valve deposits. This testing concluded that if an automotive spark-ignition engine fuel could keep intake valve deposits at or below a certain average weight per valve at the end of mileage accumulation, then that automotive spark-ignition engine fuel could be used in the BMW vehicle-engine combination for a specified period without intake valve deposits causing driveability degradation. Minimizing intake valve deposits may be necessary to maintain vehicle driveability and tailpipe emissions control.5.1.1 State and Federal Legislative and Regulatory Action—Legislative activity and rulemaking primarily by California Air Resources Board8 and the Environmental Protection Agency9 necessitate the acceptance of a standardized test method to evaluate the intake system deposit forming tendency of an automotive spark-ignition engine fuel.5.1.2 Relevance of Results—The operating conditions and design of the engine and vehicle used in this test method are not representative of all modern automobiles. These factors shall be considered when interpreting test results.5.2 Test Validity: 5.2.1 Procedural Compliance—The test results are not considered valid unless the test is completed in compliance with all requirements of this test method. Deviations from the parameter limits presented in Sections 10 and 11 will result in an invalid test. Engineering judgment shall be applied during conduct of the test method when assessing any anomalies to ensure validity of the test results.5.2.2 Vehicle Compliance—A test is not considered valid unless the vehicle met the quality control inspection requirements as described in Section 10.1.1 This test method covers a vehicle test procedure for evaluation of intake valve deposit formation of unleaded spark-ignition engine fuels. This test method uses a 1985 model BMW 318i2 vehicle. Mileage is accumulated following a specified driving schedule on either public road or test track.

A knowledge of spark-ignition engine fuel composition is useful for regulatory compliance, process control, and quality assurance.The quantitative determination of olefins and other hydrocarbon types in spark-ignition engine fuels is required to comply with government regulations.This test method is not applicable to M85 and E85 fuels, which contain 85 % methanol and ethanol, respectively.1.1 This test method provides for the quantitative determination of oxygenates, paraffins, olefins, naphthenes, and aromatics in low-olefin spark-ignition engine fuels by multidimensional gas chromatography. Each hydrocarbon type can be reported either by carbon number (see ) or as a total through C10, except for olefins, which can only be reported through C9. Higher boiling hydrocarbons cannot be reported by type and are reported as a composite group. The lower limit of detection for a single hydrocarbon component or carbon number type is 0.05 mass %.Note 1—There can be an overlap between the C9 and C10 aromatics; however, the total is accurate. Isopropyl benzene is resolved from the C8 aromatics and is included with the other C9 aromatics. Naphthalene is determined with the C11+ components.1.2 This test method is applicable for total olefins in the range from 0.05 to 13 mass %. The test method can quantitatively determine olefins in samples where the olefin concentration does not exceed 0.6 % C4 or 4.0 % C5 or 4.5 % of the combined C4 and C5. Although the precision for benzene was determined in the range from 0.3 to 1.0 mass %, this test method can be used to determine benzene concentrations up to 5.0 mass %.1.3 This test method is not intended to determine individual hydrocarbon components except for those hydrocarbon types for which there is only one component within a carbon number. Individually determined hydrocarbons are benzene, toluene, cyclopentane, propane, propylene, and cyclopentene.1.4 Precision data has only been obtained on samples containing MTBE. Application of this test method to determine other oxygenates shall be verified in the user's laboratory. Methanol cannot be determined and shall be quantitated by an appropriate oxygenate method such as Test Method D 4815 or D 5599. Methanol is fully resolved and does not interfere with the determination of other components or groups.1.5 Although specifically written for spark-ignition engine fuels containing oxygenates, this test method can also be applied to other hydrocarbon streams having similar boiling ranges, such as naphthas and reformates.1.6 The values stated in SI units are to be regarded as the standard.1.7 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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 Knowledge of the concentration of benzene may be required for regulatory use, control of gasoline blending, and/or process optimizations.1.1 This test method covers the quantitation in liquid volume percent of benzene and toluene in finished motor and aviation spark ignition fuels by gas chromatography. This test method has two procedures: Procedure A uses capillary column gas chromatography and Procedure B uses packed column gas chromatography. Procedures A and B have separate precisions.1.2 The method has been evaluated for benzene using a D6300-compliant Interlaboratory Study (ILS), with the lowest and highest ILS sample concentration means as follows: (1) Procedure A between 0.12 % and 5.2 % by volume and (2) Procedure B between 0.10 % and 5.0 % by volume.1.3 The method has been evaluated for toluene using a D6300-compliant Interlaboratory Study (ILS), with the lowest and highest ILS sample concentration means as follows: (1) Procedure A between 0.4 % and 19.7 % by volume, and (2) Procedure B between 2.0 % and 20.0 % by volume.1.4 For reporting, the lowest and highest concentration ranges for benzene and toluene for Procedure A of this test method per Practice D6300 see 13.2.1.5 For reporting, the lowest and highest concentration ranges for benzene and toluene for Procedure B of this test method per Practice D6300 see 25.2.1.6 For benzene by Procedure A, the following oxygenated fuels are included in the working range: (1) ethanol up to 20 % by volume (E20); (2) methanol up to 10 % by volume (M10). Fuels M85 and E85 were excluded.1.7 For benzene by Procedure B the following oxygenated fuels are included in the working range: (1) ethanol up to 20 % by volume (E20); (2) methanol up to 10 % by volume (M10). Fuels M85 and E85 were excluded.1.8 For toluene by Procedure A the following oxygenated fuels were included in the working range: (1) ethanol up to 20 % by volume (E20); (2) M85 and E85.1.9 For toluene by Procedure B the following oxygenated fuels are included in the working range: (1) ethanol up to 20 % by volume (E20); (2) M85 and E85.1.10 Procedure A uses MIBK as the internal standard. Procedure B uses sec-butanol as the internal standard. The use of Procedure B for fuels containing blended butanols requires that sec-butanol be below the detection limit in the fuels as sec-butanol is an internal standard. For Procedure B, an alternative separation column set described in the annex (A2.3, Annex Approach B) uses MEK as the internal standard when butanols may be blended into gasolines.1.11 This test method includes a between method bias section for benzene based on Practice D6708 bias assessment between Test Method D3606 Procedure B and Test Method D5769. It is intended to allow Test Method D3606 Procedure B to be used as a possible alternative to Test Method D5769. The Practice D6708 derived benzene correlation equation is applicable for benzene measurements in the reportable range from 0.06 % to 2.88 % by volume as reported by Test Method D3606 Procedure B (see 27.2.1). The correlation complies with EPA’s Performance Based Measurement System (PBMS).1.12 Correlation equations are included in the between test methods bias section 14.2.1 of Procedure A to convert Procedure A to the Procedure B volume percent values for benzene and toluene. The correlations are applicable in the concentration ranges of 0.07 % to 5.96 % by volume for benzene and 0.36 % to 20.64 % by volume for toluene as reported by Procedure A.1.13 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.1.14 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.1.15 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 The quantitative determination of olefins in spark-ignition engine fuels is required to comply with government regulations.5.2 Knowledge of the total olefin content provides a means to monitor the efficiency of catalytic cracking processes.5.3 This test method provides better precision for olefin content than Test Method D1319. It also provides data in a much shorter time, approximately 20 min following calibration, and maximizes automation to reduce operator labor.5.4 This test method is not applicable to M85 or E85 fuels, which contain 85 % methanol and ethanol, respectively.1.1 This test method provides for the quantitative determination of total olefins in the C4 to C10 range in spark-ignition engine fuels or related hydrocarbon streams, such as naphthas and cracked naphthas. Olefin concentrations in the range from 0.2 % by liquid-volume or mass to 5.0 % by liquid-volume or mass, or both, can be determined directly on the as-received sample whereas olefins in samples containing higher concentrations are determined after appropriate sample dilution prior to analysis.1.2 This test method is applicable to samples containing alcohols and ethers; however, samples containing greater than 15 % alcohol must be diluted. Samples containing greater than 5.0 % ether must also be diluted to the 5.0 % or less level, prior to analysis. When ethyl-tert-butylether is present, only olefins in the C4 to C9 range can be determined.1.3 This test method can not be used to determine individual olefin components.1.4 This test method can not be used to determine olefins having higher carbon numbers than C10.NOTE 1: Precision was determined only on samples containing MTBE and ethanol.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 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.1.7 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 Test Method—The data obtained from the use of this test method provide a comparative index of the fuel-saving capabilities of automotive engine oils under repeatable laboratory conditions. A baseline calibration oil (hereafter referred to as BC oil) has been established for this test to provide a standard against which all other oils can be compared. The BC oil is an SAE 5W-30 grade fully formulated lubricant. There is a direct correlation of Test Method D6837 (Sequence VIB) Fuel Economy Improvement (FEI) by percent with the fuel economy results obtained from vehicles representative of current production running under the current EPA testing cycles. The test procedure was not designed to give a precise estimate of the difference between two test oils without adequate replication. Rather, it was developed to compare a test oil to BC oil. Companion test methods used to evaluate engine oil performance for specification requirements are discussed in the latest revision of Specification D4485.5.2 Use—The Sequence VIB test method is useful for engine oil fuel economy specification acceptance. It is used in specifications and classifications of engine lubricating oils, such as the following:5.2.1 Specification D4485.5.2.2 API Publication 1509.5.2.3 SAE Classification J304.5.2.4 SAE Classification J1423.1.1 This test method covers an engine test procedure for the measurement of the effects of automotive engine oils on the fuel economy of passenger cars and light-duty trucks with gross vehicle weight of 3856 kg or less. The tests are conducted on a dynamometer test stand using a specified spark-ignition engine with a displacement of 4.6-L. It applies to multiviscosity grade oils used in these applications.1.2 This test method also provides for the running of an abbreviated length test that is referred to as the VIBSJ. The procedure for VIBSJ is identical to the Sequence VIB with the exception of the items specifically listed in Annex A13. The procedure modifications listed in Annex A13 refer to the corresponding section of the Sequence VIB test method.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3.1 Exceptions—Where there is no direct SI equivalent such as screw threads, National Pipe Threads/diameters, tubing size, or single source supply equipment specifications.

1.1 This test method covers an engine test procedure for evaluating automotive engine oils for certain high-temperature performance characteristics, including oil thickening, sludge and varnish deposition, and oil consumption, as well as engine wear. Such oils include both single viscosity grade and multiviscosity grade oils which are used in both spark-ignition, gasoline-fueled engines, as well as in diesel engines. Note 1-Companion test methods used to evaluate engine oil performance for specification requirements are discussed in SAE J304. 1.2 The values stated in either acceptable metric units or in other units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way. 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 and health practices and determine the applicability of regulatory limitations prior to use. 1.4 This test method is arranged as follows: Subject Section Introduction 1 Referenced Documents 2 Terminology 3 Summary of Test Method 4 Significance and Use 5 Apparatus 6 Laboratory 6.1 Drawings 6.2 Specified Equipment 6.3 Test Engine 6.4 Engine Parts 6.4.1 Hold-Back Fixture 6.4.2 Engine Speed and Load Control 6.5 Engine Cooling System 6.6 Flushing Tank 6.7 Coolant Mixing Tank 6.8 Jacketed Rocker Cover, Intake Manifold Crossover, and Breather Tube Cooling Systems 6.9 External Oil-Cooling System 6.10 Fuel System 6.11 Carburetor Air Supply Humidity, Temperature, and Pressure 6.12 Temperature Measurement 6.13 Thermocouple Location 6.13.1 Air-to-Fuel Ratio Determination 6.14 Exhaust and Exhaust Back Pressure Systems 6.15 Blowby Flow Rate Measurement 6.16 Pressure Measurement and Pressure Sensor Location 6.17 Reagents and Materials 7.

5.1 A knowledge of spark-ignition engine fuel composition is useful for regulatory compliance, process control, and quality assurance.5.2 The quantitative determination of olefins and other hydrocarbon types in spark-ignition engine fuels is required to comply with government regulations.5.3 This test method is not applicable to M85 fuels, which contain 85 % methanol.1.1 This test method covers the quantitative determination of saturates, olefins, aromatics, and oxygenates in spark-ignition engine fuels by multidimensional gas chromatography. Each hydrocarbon type can be reported either by carbon number (see Note 1) or as a total.NOTE 1: There can be an overlap between the C9 and C10 aromatics; however, the total is accurate. Isopropyl benzene is resolved from the C8 aromatics and is included with the other C9 aromatics.1.2 This test method is not intended to determine individual hydrocarbon components except benzene and toluene.1.3 This test method is divided into two parts, Part A and Part B.1.3.1 Part A is applicable to the concentration ranges for which precision (Table 10 and Table 11) has been obtained:Property Units Applicable rangeTotal aromatics Volume % 19.32 to 46.29Total saturates Volume % 26.85 to 79.31Total olefins Volume % 0.40 to 26.85Oxygenates Volume % 0.61 to 9.85Oxygen Content Mass % 2.01 to 12.32Benzene Volume % 0.38 to 1.98Toluene Volume % 5.85 to 31.65Methanol Volume % 1.05 to 16.96Ethanol Volume % 0.50 to 17.86MTBE Volume % 0.99 to 15.70ETBE Volume % 0.99 to 15.49TAME Volume % 0.99 to 5.92TAEE Volume % 0.98 to 15.591.3.1.1 This test method is specifically developed for the analysis of automotive motor gasoline that contains oxygenates, but it also applies to other hydrocarbon streams having similar boiling ranges, such as naphthas and reformates.1.3.2 Part B describes the procedure for the analysis of oxygenated groups (ethanol, methanol, ethers, C3 to C5 alcohols) in ethanol fuels containing an ethanol volume fraction between 50 % and 85 % (17 % to 29 % oxygen). The gasoline is diluted with an oxygenate-free component to lower the ethanol content to a value below 20 % before the analysis by GC. The diluting solvent should not be considered in the integration, this makes it possible to report the results of the undiluted sample after normalization to 100 %.1.4 Oxygenates as specified in Test Method D4815 have been verified not to interfere with hydrocarbons. Within the round robin sample set, the following oxygenates have been tested: MTBE, ethanol, ETBE, TAME, iso-propanol, isobutanol, tert-butanol and methanol. Applicability of this test method has also been verified for the determination of n-propanol, acetone, and di-isopropyl ether (DIPE). However, no precision data have been determined for these compounds.1.4.1 Other oxygenates can be determined and quantified using Test Method D4815 or D5599.1.5 The method is harmonized with ISO 22854.1.6 This test method includes a relative bias section for U.S. EPA spark-ignition engine fuel regulations for total olefins reporting based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D1319 as a possible Test Method D6839 alternative to Test Method D1319. The Practice D6708 derived correlation equation is only applicable for fuels in the total olefins concentration range from 0.2 % to 18.2 % by volume as measured by Test Method D6839. The applicable Test Method D1319 range for total olefins is from 0.6 % to 20.6 % by volume as reported by Test Method D1319.1.7 This test method includes a relative bias section for reporting benzene based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D3606 (Procedure B) as a possible Test Method D6839 alternative to Test Method D3606 (Procedure B). The Practice D6708 derived correlation equation is only applicable for fuels in the benzene concentration range from 0.52 % to 1.67 % by volume as measured by Test Method D6839.1.8 This test method includes a relative bias section for reporting benzene based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D5580 as a possible Test Method D6839 alternative to Test Method D5580. The Practice D6708 derived correlation equation is only applicable for fuels in the benzene concentration range from 0.52 % to 1.67 % by volume as measured by Test Method D6839.1.9 This test method includes a relative bias section for reporting benzene based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D5769 as a possible Test Method D6839 alternative to Test Method D5769. The Practice D6708 derived correlation equation is only applicable for fuels in the benzene concentration range from 0.52 % to 1.67 % by volume as measured by Test Method D6839.1.10 This test method includes a relative bias section for reporting total aromatics based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D1319 as a possible Test Method D6839 alternative to Test Method D1319. The Practice D6708 derived correlation equation is only applicable for fuels in the total aromatics concentration range from 14.3 % to 31.2 % by volume as measured by Test Method D6839.1.11 This test method includes a relative bias section for reporting total aromatics based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D5580 as a possible Test Method D6839 alternative to Test Method D5580. The Practice D6708 derived correlation equation is only applicable for fuels in the total aromatics concentration range from 14.3 % to 31.2 % by volume as measured by Test Method D6839.1.12 This test method includes a relative bias section for reporting total aromatics based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D5769 as a possible Test Method D6839 alternative to Test Method D5769. The Practice D6708 derived correlation equation is only applicable for fuels in the total aromatics concentration range from 14.3 % to 30.1 % by volume as measured by Test Method D6839.1.13 This test method includes a relative bias section for reporting total olefins based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D6550 as a possible Test Method D6839 alternative to Test Method D6550.
