The history of Lubrication 8

Part 7

Petrol engines
SA	Here the petrol and diesel engines are not yet separated. There are still no special requirements of the engine manufacturers e.g. for corrosion protection. This oil is only advisable if the manufacturer expressly demanded.
SB	Only for petrol engines with additives against wear, oil aging and corrosion. It is used in engines after 1930 and should be used only if the manufacturer expressly request it.
SC	Oil used in cars and light commercial for normal performance requirements from 1964, the contains additional ingredients against cold sludge formation and oil coking and even tested in different temperature ranges.
SD	This oil corresponds to the more stringent requirements since 1968. It is assigned the same group of enginesas oil of the category 'SC'.
SE	All oils mentioned up to this point, including this one from 1972 with again more stringent requirements (e.g. stop and go) apply obsolete for modern vehicles and should no longer be used.
SF	This since 1980 standardized could, provided the appropriate note of the manufacturer, also still be used in today's (2011) engines. The requirement is that no special demands e.g. by charging exist. It surpasses SE oils in terms of oxidation stability and protection against wear and sludge-carrying capacity.
SG	This oil from 1988 one says especially improved characteristics in the carry behavior of solid materials and solids and atoxidation protection
SH	For this oil, since 1994, are more stringent test conditions, etc. of the American Chemistry Councils. Of course, for example to wear protection again increased demands are made. Important here is that this oil is suitable for turbocharged engines.
SJ	Petrol engines from 1997 are scheduled for this oil. It corresponds to the increased requirements inrespect to evaporation tendency, oxidation stability and reduced phosphorus content.
SL	As part of extended oil change intervals this oil from 2001 also satisfied special tasks in the field of wear, aging, and thus connected the receipt of the viscosity.
SM	This oil standard applies to petrol engines from 2004.

Diesel engines
CA	Oil for light duty of the diesel engine and a fuel up to 0.95% sulfur content.
CB	Also for not very highly stressed diesel engines and for fuel starting 0.95%. The oil must already better deal with attrition and other possible solids.
CC	This from 1961 valid oil norm is also already responsible for light-charged engines. For hard-working petrol engines, this oil is also suitable, but is there more to protect against corrosion.
CD	This oil must be able to to deal more effectively with high sulfur content in fuel. Special oils for this service were introduced in 1955 and offer protection against high temperature deposits and bearing corrosion.
CD+	For high-performance diesel engines. These oils are designed for extended oil change intervals allowed depending on the manufacturer's instructions
CE	Motor oils since 1983 for heaviest stress, especially for diesel engines with turbocharger or compressor. These oils meet the additional demands in relation to the tests for oil thickening, wear, oil consumption and piston cleanliness.
CF-4	Since 1990, typical for four-stroke diesel engines with very high speeds. The oils offer an improved control of the oil consumption and piston deposits. They are particularly suitable for highway driving and heavy trucks.
CF	Since 1994, typical for diesel engines with combustion chamber method and other diesel engines, a wide range of fuel types using, including fuel with high sulfur content, e.g. more than 5%. It is necessary an effective control of piston deposits, wear and copper-containing bearing corrosion.
CG-4	This oil is suitable for use in four-stroke diesel engines with very high performance requirements (0.05% low sulfur fuel). These oils provide effective control of piston deposits at high temperatures, wear, corrosion, foaming, oxidation stability and carbon black accumulation. Are especially effective in engines meet the emission standards from 1994.
CH-4	Suitable for four-stroke diesel engines with high rpm, developed to fulfill the emission standard by 1998 and specially designed for use with diesel fuels with a sulfur content up to 0.5%. CH-4 oils are superior in performance and can effectively lubricate engines.
CI-4	Oils for use in four-stroke diesel engines with high rpm level, to meet the emissions standards 2004. Intended for use in all diesel fuels up to a sulfur content of 0.05% and particularly effective for the lifetime of the engine, in the can be used exhaust gas recirculation (EGR) and other components of the exhaust gas regulations. Provides inter alia corrosion protection, protection against deposits on pistons and camshaft wear, foaming and loss of viscosity due to boost.
CJ-4	Motor oils correspond with the, starting in 2006 by the automotive industry fixed performance requirements for diesel engines (especially exhaust gas treatment systems).
CJ-4Plus	According to the highest standards set for diesel engines, offer a higher level of protection against carbon black-related increase in the viscosity and viscosity loss by boost in diesel engines.
