For an adequate use of this product, bear in mind that there are basically two international classification systems, approved by Chile, which allow the selection of a lubricating oil according to its quality:
-CC (engines since 1961) -CD (engines since 1955) -CD-II (2-stroke engines, since 1988) -CE (engines since 1983) -CF-4 (engines since 1991) -CF (engines since 1994) -CF-2 (2-stroke engines, since 1994) -CG-4 (engines since 1994) -CH-4 (engines since 1998) -CI-4 (engines since 2002).
Lubricating oils that comply with a higher API category level can also be used, when recommended, in lower categories (older engines), information that is indicated on the labeling of the containers, for example:
Lubricating oils formulated for “mixed fleets” can also be found on the market, combining specifications for both Gasoline and Diesel engines, in accordance with the technical specifications recommended by vehicle manufacturers, information which is labeled on the containers, such as:
Gasoline engines 1993. It has the same requirements as for SG service, but adds a system of licensing and registration of engine tests and formulas to provide greater quality assurance. The API symbol, which truly certifies the SH level, is the “doughnut” on the can.
Gasoline engines 1996. Same requirements as for SH service (including licensing and certification system), along with improved protection against high temperature oil oxidation and catalyst poisoning. The API “donut” on the drum certifies the SJ level. As of 01/08/97, the SJ level officially replaces the SH level.
Gasoline engine 2001. New wear (Seq IVa), detergency (TEOST MHT4), oxidation (Seq III f, equivalent to Seq III e) and low temperature deposit (Seq V g) tests for better engine protection and longer lubricant life. Replaces API SJ.
Gasoline engine 2004. Improved overall performance for longer oil changes. Severified TEOST test, new oxidation test (Seq IIIG, equivalent to 2 Seq IIIF). Chemical limits for fluid grades with ILSAC GF-4.
Table api oils
Current and previous ILSAC standards are listed here. Vehicle owners should consult their owner’s manuals before referring to these tables. Oils may have more than one performance level.
CAUTION: Not suitable for use in most gasoline-powered automobile engines manufactured after 1996. May not provide adequate protection against rust, wear or sludge buildup in the engine.
CAUTION: Not suitable for use in most gasoline-powered automobile engines manufactured after 1993. May not provide adequate protection against rust, wear or sludge buildup in the engine.
CAUTION: Not suitable for use in most gasoline-powered automobile engines manufactured after 1988. May not provide adequate protection against sludge buildup in the engine.
CAUTION: Not suitable for use in most diesel automobile engines manufactured after 2009. Two-stroke cycle engines may have different lubrication requirements than four-stroke engines, so contact the manufacturer for current lubrication recommendations.
What does sae mean in oils
Lubricant means any substance which, regardless of its physical state (solid, semi-solid or liquid), serves to reduce the detrimental effect of friction on the durability of two surfaces in contact, at least one of which is in motion. Lubricants can be presented in different physical states: solids such as molybdenum disulfide (MoS2) or liquids such as oil.
As mentioned above, the use of lubricating oils in vehicle engines is of vital importance as they form a protective film on the moving parts of the engine, which helps to reduce friction between the different components, thus reducing wear of the parts and preventing power losses.
But in addition to lubricating the moving parts, engine lubricating oils also have a cleaning function for the internal parts of the engine, since they contain detergent and dispersant additives that prevent the formation of solid compounds and deposits of impurities derived from combustion.
