Gasoline Sequences
A1 Oil intended for use in gasoline engines specifically designed to be capable of using low friction, low viscosity oils with a High Temperature / High Shear Rate Viscosity of 2.9 to 3.5 mPa.s. These oils may be unsuitable for use in some engines. Consult owner manual or handbook if in doubt.
A2 General purpose oil intended for use in most gasoline engines with normal drain intervals, although it may not be suitable for some high performance engines.
A3 Stable, stay-in-grade oil intended for use in high performance gasoline engines and / or for extended drain intervals where specified by the engine manufacturer, and / or for year-round use of low viscosity oils, and/or for severe operating conditions as defined by the engine manufacturer.
Light duty diesel Sequences
B1 Oil intended for use in car and light van diesel engines specifically designed to be capable of using low friction, low viscosity oils with a High temperature / High shear rate viscosity of 2.9 to 3.5 mPa.s. These oils may be unsuitable for use in some engines. Consult owner manual or handbook if in doubt.
B2 General purpose oil intended for use in most car and light van diesel engines (primarily indirect injection) with normal drain intervals, although it may not be suitable for some high performance engines.
B3 Stable, stay-in-grade oil intended for use in high performance car and light van diesel engines (primarily indirect injection) and / or for extended drain intervals where specified by the engine manufacturer, and / or for year-round use of low viscosity oils, and/or for severe operating conditions as defined by the engine manufacturer.
B4 Oil intended primarily for use in car and light van direct injection diesel engines where special quality oils are required.
Heavy duty diesel Sequences
E2 General purpose oil for naturally aspirated and turbocharged heavy duty diesel engines, medium to heavy duty cycles and mostly normal oil drain intervals
E3 This lubricant category provides effective control with respect to piston cleanliness, bore polishing, wear, soot handling and lubricant stability. It is therefore recommended for diesel engines meeting Euro 1 and Euro 2 emission requirements running under severe conditions. It is also suitable for extended oil drain intervals according to the manufacturer's recommendations.
E4 Stable, stay-in-grade oil providing further control of piston cleanliness, wear, soot handling and lubricant stability compared to E3. It is recommended for highly rated diesel engines meeting Euro 1, Euro 2 and Euro 3 emission requirements and running under very severe conditions, e.g. significantly extended oil drain intervals according to the manufacturers recommendations.
E5 Stable, stay-in-grade oil providing effective control with respect to piston cleanliness and bore polishing. It further provides wear and turbocharger deposit control, soot handling and lubricant stability compared to
E3. It is recommended for highly rated diesel engines meeting Euro 1, Euro 2 and Euro 3 emission requirements and running under severe conditions, e.g. extended oil drain intervals according to the manufacturers recommendations.
