ILSAC GF 2 – Oil must meet both API SJ and EC-II requirements. ILSAC GF 1 – Oil meets both API SH and Energy Conserving II (EC-II) requirements, the minimum requirement for oils. These oils are blended to a high temperature high shear (HTHS) viscosity range of 2.9cP–3.2cP to assist in reducing GHG emissions. Refer to individual engine manufacturer recommendations regarding compatibility with API FA-4 oils. These oils are formulated for use in on-highway applications with diesel fuel sulfur content up to 15 ppm (0.0015% by weight). Consult manufacturer if using oil with higher than 15 ppm.įA – 4 – Current, API Service Category FA-4 describes certain XW-30 oils specifically formulated for use in select high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway greenhouse gas (GHG) emission standards. Use of these oils with greater than 15 ppm (0.0015% by weight) sulfur fuel may impact exhaust aftertreatment system durability and drain interval. Formulated for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). Consult manufacturer if using oil with higher than 15 ppm.ĬK – 4 – Current, For high speed four-stroke diesel engines designed to meet 2017 on-highway and tier 4 non-road exhaust emission standards. May also qualify as CI-4 PLUS.ĬJ – 4 – Current, For high speed four-stroke diesel engines designed to meet 2010 on-highway and tier 4 non-road exhaust emission standards. Formulated to sustain engine durability where exhaust gas recirculation (EGR) is used and are intended for use with diesel fuels ranging in sulfur content up to 0.5% weight. For high speed, four stroke engines designed to meet 2002 emission standards. Consult manufacturer for two-stroke recommendationsĬF-4 - Obsolete, not suitable for engines built after 2009.ĬG – 4 - Obsolete, not suitable for engines built after 2009.ĬH-4 – Current, for high speed, four stroke engines designed to meet exhaust emission standardsĬI-4 – Current, Introduced in 2002. (WARNING: Lubricants in these classifications may not provide adequate sludge protection)ĬA – Obsolete, Obsolete, not suitable for engines built after 1959.ĬB - Obsolete, not suitable for engines built after 1961.ĬC - Obsolete, not suitable for engines built after 1990.ĬD - Obsolete, not suitable for engines built after 1994.ĬD II - Obsolete, not suitable for engines built after 1994.ĬE - Obsolete, not suitable for engines built after 1994.ĬF - Obsolete, not suitable for engines built after 1994.ĬF -2 - Obsolete, not suitable for engines built after 2009. SH - Obsolete, not suitable for engines built after 1996. SG -Obsolete, not suitable for engines built after 1993. SF - Obsolete, not suitable for engines built after 1988. SE - Obsolete, not suitable for engines built after 1979. (WARNING: Lubricants in these classifications may cause damage to modern engines) SD - Obsolete, not suitable for engines built after 1971. SC - Obsolete, not suitable for engines built after 1967. SB – Obsolete, not suitable for engines built after 1951. SA – Obsolete, not suitable for engines built after 1930. Remember, always check your user’s manual to determine what lubricant you should consider. Now that we are familiar with them, lets look at some of their standards and classifications. Too low a viscosity and the oil will fail to provide enough lubrication for protection, or is likely to leak from the system.We have already discussed some of the organizations that classify lubricants. If an oil’s viscosity is too high, it will not circulate around and in between the moving parts as it should, leading to excessive engine wear, poor fuel economy and the risk of an expensive engine seizure. It includes viscosity, along with a few other attributes that the engine’s design requires. When does ‘weight’ not mean what something weighs? When its used in by an oil supplier! The weight grade of an oil actually refers to its behaviour, in relation to its temperature. So, if the oil industry hadn’t confused things enough with their letters and acronyms, they threw in another term – “weight”. This is to see how the oil performs on cold starts and at normal engine operating temperature. A set of cold tests are performed below freezing temperatures and another set conducted at over 100 degrees Celsius. No, these numbers are the oil’s grade or rating given to an oil blend after going through a number of tests.
