Brief discussion about motor oils in general...

Viscosity
Viscosity is a variable quantity that depends on temperature. During the operation of an automotive engine, there are also changes in operating temperatures. For proper lubrication efficiency, the viscosity of the oil should change as little as possible with temperature. This dependency is determined by the so-called viscosity index. The higher this index, the lower the viscosity dependency on temperature changes. The viscosity characteristics of motor oils are specified according to SAE (Society of Automotive Engineers, USA). For oil classification, this standard uses 6 winter classes designated by a number and "W" (for Winter) and 5 summer classes designated by a number.

Winter classes: 0W, 5W, 10W, 15W, 20W, 25W (-35°C, -30°C, -25°C, -20°C, -15°C, -10°C)
Summer classes: 20, 30, 40, 50, 60 (20°C, 30°C, 40°C, 50°C, 60°C)
The winter marking value indicates the behavior of the oil at low temperatures (e.g., SAE 15W oil has a pumpability limit of -25 °C).

The summer marking value indicates the use of oil at high temperatures.

temperatures. If only one class is used in the designation, it means that it is a monograde oil (summer or winter). When a combination of summer and winter grades is used (e.g., 5W-40), it is a multigrade oil or all-season oil. Currently, multigrade motor oils are almost exclusively used.

Performance categories
They characterize both the immediate and long-term properties of motor oil under various forms of operational load. Various properties are assessed, such as oxidative stability, volatility, wear protection, deposit formation, corrosion protection, fuel economy, etc.

The following standards are used to designate performance categories of motor oils:
API classification (American Petroleum Institute, USA)
ACEA classification (European Automobile Manufacturers Association, EU)
corporate standards of engine and vehicle manufacturers (VW, MB, MAN, VOLVO, TATRA)
MIL-L classification (U.S. Army standards)
other classifications (e.g., ILSAC)
Currently, the most influential specifications are those of API, ACEA, and the corporate standards of engine and vehicle manufacturers. The CCMC classification is already outdated and is mentioned only temporarily.

API classification
According to this standard, motor oils are classified by use into oils for spark-ignition (petrol) engines, designated by the letter "S" (from the English Service), and for compression-ignition (diesel) engines, designated by the letter "C" (from the English Commercial). Most oils can be used in both types of engines and are then marked with a combination of both letters, e.g., SL/CF.

Performance classes for spark-ignition engines
SA - Oils without additives for engines operating in mild conditions with low loads, produced between 1940 and 1950.
SB - Oils with additives to prevent deposit formation for engines produced between 1951 and 1963.
SC - Oils with additives to prevent deposit formation and low-temperature sludge for engines produced between 1964 and 1967.
SD - Additized oils with detergent and dispersant additives for engines produced between 1968 and 1971.
SE - Oils for highly stressed engines produced between 1971 and 1979.
SF - Oils for very highly stressed engines produced between 1980 and 1988.
SG - Oils for engines produced between 1988 and 1993 that meet the most stringent requirements for minimizing wear and deposit formation.
SH - Oils with the same properties as SG but tested under more demanding standards. Designed for engines produced in 1996 and older.
SJ - Oil for engines produced in 2001 and older.
SL - Oils exceeding API SJ with increased fuel economy and extended service intervals.
SM - Oils of the highest quality exceeding API SL with increased oxidative stability, better wear, and deposit protection. Effective since 2004.

Oils for spark-ignition and light diesel engines
A1/B1 - Oils Additized to prevent deposit formation on pistons, sludge formation, wear, and oxidation at high temperatures. They meet requirements for super-light operation and fuel economy. Suitable only for certain engines.
A3/B3 - Oils intended for heavily loaded spark-ignition and diesel engines or for extended service intervals per manufacturer’s recommendations.
A3/B4 - Oils for high-performance spark-ignition engines and diesel engines with direct fuel injection, also suitable for use as described in category B3.
A5/B5 - Highly stable oils designed for extended service intervals in heavily loaded spark-ignition and diesel engines. They meet requirements for super-light operation and fuel economy. Suitable only for specially designed engines.
Catalyst-compatible oils - for spark...light and heavy-duty diesel engines
C1 - Oils designed for use with DPF (diesel particulate filter) and TWC (three-way catalyst) in high-performance engines requiring low viscosity oil with low SAPS (chemical limits) and with a high-temperature high shear viscosity (HTHSV) greater than 2.9 mPa.s. These oils extend the lifespan of catalysts and reduce fuel consumption. They are suitable only for specially designed engines.
C2 - Oils for use with DPF and TWC in high-performance engines designed for low viscosity oils with HTHSV greater than 2.9 mPa.s. These oils extend the lifespan of DPF and TWC catalysts and reduce fuel consumption. They are suitable only for specially designed engines.
C3 - Oils for use with DPF and TWC in high-performance engines. They extend the lifespan of DPF and TWC catalysts. They are suitable only for specially designed engines.
Oils for diesel engines of commercial vehicles
E2 - Common use oils for naturally aspirated and turbocharged engines, moderately to heavily loaded and with normal change intervals.
E4 - Oils providing excellent protection for cylinder cleanliness – against wear and soot. They are recommended for high-performance engines meeting Euro 1, Euro 2, Euro 3, and Euro 4 emissions limits, operating under heavy conditions, such as extended change intervals, according to the engine manufacturer's recommendations. They are suitable for engines without particulate filters and for some engines equipped with exhaust gas recirculation or SCR (selective catalytic reduction) systems, depending on the engine manufacturer's recommendations.
E6 - Oils providing excellent protection for cylinder cleanliness – against wear and soot. They are recommended for high-performance engines meeting Euro 1, Euro 2, Euro 3, and Euro 4 emissions limits, operating under heavy conditions, such as extended change intervals, according to the engine manufacturer's recommendations. They are suitable for engines equipped with exhaust gas recirculation with or without particulate filters and for engines with SCR systems. E6 – quality specifically recommended for engines with particulate filters and is qualified in combination with low-sulfur fuel (max. 50 ppm). However, always follow the engine manufacturer's recommendations.
E7 - Oils providing effective cleanliness protection and against cylinder polishing. They also provide improved protection against wear, deposits, and soot. They are recommended for high-performance engines meeting Euro 1, Euro 2, Euro 3, and Euro 4 emissions limits, operating under heavy conditions, such as extended change intervals, according to the engine manufacturer's recommendations. They are suitable for engines without particulate filters and for most engines equipped with exhaust gas recirculation or SCR systems, according to the engine manufacturers' recommendations.
Note: Categories A2 and B2 are not included in the current release. However, they remain valid in the latest version until manufacturers recommend them in service manuals.
Categories E3 and E5 are replaced by categories E6 and E7.

Explanations:

DPF (Diesel Particulate Filter) - diesel particulate filter
TWC (Three Way Catalyst) - three-way catalyst
EGR (Exhaust Gas Recirculation) - exhaust gas recirculation
SCR (Selective Catalytic Reduction) - selective catalytic reduction of NOx: treatment of exhaust gas composition with urea (agent AdBlue = 32.5% aqueous solution of urea)

Manufacturer and engine standards
Many manufacturers of automobiles and engines require motor oils to meet additional requirements not included in the previous classification methodology.


How to correctly select motor oil?
1. The first principle in selecting motor oil isFollow the manufacturer's instructions for the motorcycle, as contained in the manual for each vehicle. Only the manufacturer of the engine (vehicle) can responsibly say which oil can be used. Practically no manufacturer recommends a specific brand of oil (it contradicts the competition laws in the European Union). Manufacturers (of cars) recommend oils according to the so-called performance specifications, for example API SH/CD, ACEA A3, VW 505.00, MB 229.1 and viscosity specifications SAE, for example 15W-40, 10W-40. Change intervals are then determined for such recommended oils.
2. For oils of the same performance specification, the same change interval is recommended.
3. If you do not have the vehicle manual, ask the manufacturer. Remember, the vehicle manufacturer does not recommend a brand of oil, only the performance and viscosity specifications.
4. If the oil meets the performance and viscosity specifications (or a higher specification), it can be used. A higher performance level is not a problem, but it is usually more expensive and does not bring much additional benefit.
5. If you are changing an oil of a low-performance specification (M5AD, M6AD) to a new high-performance oil, shorten the change interval for the first change (there will be a flushing of deposits).
6. Do not mix mineral oils (SAE 15W-40, 15W-50, 20W-30, 40) with synthetic oils (SAE 0W and 5W-30, 40, 50).
