ISO 6743-15:2007以表格形式对下列内燃机中使用的发动机润滑油进行了详细分类:采用曲轴箱扫气系统的二冲程火花点火式汽油发动机，用于交通、休闲和公用事业应用，如摩托车、雪地摩托、，电锯（以下简称二冲程发动机油）和四冲程循环中的火花点火式汽油发动机，它们使用一个共用油槽，其中包含摩托车、摩托车、全地形车（ATV）和相关设备（以下简称四冲程发动机油）的发动机和传动系/起动机/变速器的润滑剂。 描述了舷外发动机和船用发动机的应用。 预计ISO 6743-15:2007将与ISO 6743-99一起阅读。

ISO 6743-15:2007 establishes the detailed classification, in tabular form, of engine lubricating oils for use in the following internal combustion engines: two-stroke cycle, spark-ignition gasoline engines that employ a crankcase scavenging system and are used in transportation, leisure and utility applications, such as motorcycles, snowmobiles, chainsaws (hereinafter referred to as two-stroke engine oils) and in four-stroke cycle, spark-ignition gasoline engines that employ a common sump containing the lubricant for both the engine and the drive train/starter/transmission of motorcycles, motor scooters, all-terrain vehicles (ATVs) and related equipment (hereinafter referred to as four-stroke engine oils). Outboard motor and marine engine applications are described. It is expected that ISO 6743-15:2007 be read in conjunction with ISO 6743-99.
