A brief discussion on motor oils in general.

Viscosity
Viscosity is a variable quantity that depends on temperature. During the operation of an automotive engine, operational temperatures change among other things. For good lubrication efficiency, it is important that the viscosity of the oil changes as little as possible depending on the temperature. This dependency is determined by the so-called viscosity index. The higher this index, the lower the dependence of viscosity 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 grades labeled with a number and “W” (from English Winter) and 5 summer grades labeled with a number.

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

The summer grade value determines the use of the oil at summer temperatures. If only one number is used in the designation...not classified, which means they are monograde oils (summer or winter). When a combination of summer and winter grades is used (e.g. 5W-40), it is a multigrade or all-season oil. Currently, multigrade motor oils are almost exclusively used.

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

To designate the performance category of motor oils, the following standards are used:
API classification (American Petroleum Institute, USA)
ACEA classification (Association des Constructeurs Européens d' Automobile, EU)
manufacturer's specifications for engines and vehicles (VW, MB, MAN, VOLVO, TATRA)
MIL-L classification (U.S. Army standards)
other classifications (e.g. ILSAC)
Currently, the most significant specifications are API, ACEA, and manufacturers' specifications for engines and vehicles. The CCMC classification is already outdated and is mentioned only temporarily.

API Classification
According to this standard, motor oils are distinguished based on their use for gasoline engines, marked with the letter "S" (from English Service), and for diesel engines, marked with the letter "C" (from English Commercial). Most oils are suitable for both types of engines and are then labeled with a combination of both letters, e.g. SL/CF.

Performance Classes for Gasoline Engines
SA - Oils without additives for engines operating under mild conditions with low load, produced from 1940 – 1950.
SB - Oils with additives to prevent deposit formation for engines produced from 1951 – 1963.
SC - Oils with additives to prevent deposit formation and low-temperature sludge for engines produced from 1964 – 1967.
SD - Additized oils with detergent and dispersant additives for engines produced from 1968 – 1971.
SE - Oils for highly stressed engines produced from 1971 – 1979.
SF - Oils for very high-stressed engines produced from 1980 – 1988.
SG - Oils for engines produced from 1988 – 1993 that meet the strictest requirements for minimizing wear and sludge formation.
SH - Oils with the same properties as SG but tested according to 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 oil change intervals.
SM - Oils of the highest quality exceeding API SL with increased oxidation stability, better wear and sludge protection. Effective from 2004.

Oils for Gasoline and Light Diesel Engines
A1/B1 - Oils additized to prevent deposit formation on the piston, sludge formation, wear, and oxidation at high temperatures. They meet the requirements for super lightweight operation and fuel economy. They are suitable only for certain engines.
A3/B3 - Oils intended for highly stressed gasoline and diesel engines or for extended oil change intervals as recommended by the engine manufacturer.
A3/B4 - Oils for high-performance gasoline engines and diesel engines with direct fuel injection, also suitable for use described in category B3.
A5/B5 - Highly stable oils designed for extended oil change intervals in highly stressed gasoline and diesel engines. They meet the requirements for super lightweight operation and fuel economy. They are suitable only for specially designed engines.
Catalyst-compatible oils – for gasoline and light diesel engines
C1 - Oils designed foruse 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 high-temperature viscosity and high shear stress (HTHSV) greater than 2.9 mPa.s. The oils extend the life of the catalysts and reduce fuel consumption. They are suitable only for specially designed engines.
C2 - Oils for use with DPF and TWC catalysts in high-performance engines designed for low viscosity oils with HTHSV greater than 2.9 mPa.s. The oils extend the life of the DPF and TWC catalysts and reduce fuel consumption. They are suitable only for specially designed engines.
C3 - Oils for use with DPF and TWC catalysts in high-performance engines. They extend the life of the DPF and TWC catalysts. They are suitable only for specially designed engines.
Oils for diesel engines of trucks
E2 - Common use oils for naturally aspirated and turbocharged engines, moderately to heavily loaded and with normal oil change intervals.
E4 - Oils providing excellent protection of cylinder cleanliness – against wear and carbon buildup. They are recommended for high-performance engines meeting Euro 1, Euro 2, Euro 3, and Euro 4 emission limits, operating under severe conditions, such as extended oil change intervals, according to the 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, according to the manufacturer's recommendations.
E6 - Oils providing excellent protection of cylinder cleanliness – against wear and carbon buildup. They are recommended for high-performance engines meeting Euro 1, Euro 2, Euro 3, and Euro 4 emission limits, operating under severe conditions, such as extended oil change intervals, according to the 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 particularly recommended for engines with particulate filters and is qualified in combination with low-sulfur fuel (max. 50 ppm). However, always follow the manufacturer's recommendations.
E7 - Oils providing effective protection of cleanliness and against cylinder scuffing. They further provide improved protection against wear, deposits, and carbon buildup. They are recommended for high-performance engines meeting Euro 1, Euro 2, Euro 3, and Euro 4 emission limits, operating under severe conditions, such as extended oil change intervals, according to the 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 manufacturer's recommendations.
Note: Categories A2 and B2 are not included in the current edition. However, they remain valid in their last version as long as they are recommended in the service books by car manufacturers.
Categories E3 and E5 are replaced by categories E6 and E7.

Explanations:

DPF (Diesel Particulate Filter) - 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: adjustment of exhaust gas composition with urea (AdBlue = 32.5% aqueous solution of urea)

Automaker and engine manufacturer standards
Many automakers and engine manufacturers require motor oils to meet additional requirements that are not included in the previous classification method.


How to correctly choose motor oil?
1. The first principle when choosing motor oil is to follow the motorcycle manufacturer's instructions contained in the manual.at each vehicle. Only the engine manufacturer (of the vehicle) can responsibly say which oil can be used. Practically no manufacturer recommends a specific brand of oil (it contradicts competition laws in the European Union). Manufacturers (of cars) recommend oils according to so-called performance specifications, e.g., API SH/CD, ACEA A3, VW 505.00, MB 229.1, and viscosity specifications SAE, e.g., 15W-40, 10W-40. The oil recommended this way has exchange intervals specified.
2. The same exchange interval is recommended for oils of the same performance specification.
3. If you do not have a vehicle manual, ask the manufacturer. Remember, the manufacturer of the vehicle does not recommend a brand of oil, but 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 may not bring much benefit.
5. If you are changing oil of a low performance specification (M5AD, M6AD) for new high-performance oil, shorten the exchange interval for the first change (there will be a cleansing 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).
