A brief treatise on motor oils in general...

Viscosity
Viscosity is a variable that depends on temperature. During the operation of the vehicle engine, there are also changes in operating temperatures. For good 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 dependency of viscosity on temperature changes. The SAE (Society of Automotive Engineers, USA) specification is used to characterize the viscosity properties of motor oils. This standard uses 6 winter classes marked by a number and "W" (from English Winter) and 5 summer classes marked 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 name value determines the oil's behavior at low temperatures (for example, SAE 15W oil has a pouring point of -25 °C).

The summer name value determines the oil's use at summer temperatures. If only one...not grades, this 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 engine oils are almost exclusively used.

Performance Categories
They characterize both immediate and long-term properties of engine oil under different types of operational loads. Various properties are evaluated, such as oxidative stability, volatility, wear protection, deposit formation, corrosion resistance, fuel economy, etc.

The following standards are used to designate the performance category of engine 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. military standards)
other classifications (e.g., ILSAC)
Currently, the most significant are the API, ACEA, and corporate standards of engine and vehicle manufacturers. The CCMC classification is already outdated and is only mentioned temporarily.

API Classification
According to this standard, engine oils are distinguished by use into oils for spark-ignition (gasoline) engines, designated by the letter "S" (from English Service), and oils for compression-ignition (diesel) engines, designated by the letter "C" (from English Commercial). Most oils are suitable for 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 under mild conditions with low load, produced between 1940 and 1950.
SB - Oils with deposit-forming additives for engines produced between 1951 and 1963.
SC - Oils with deposit-forming additives 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 heavily loaded engines produced between 1971 and 1979.
SF - Oils for highly loaded engines produced between 1980 and 1988.
SG - Oils for engines produced between 1988 and 1993, meeting the strictest requirements for minimizing wear and deposit formation.
SH - Oils with the same properties as SG but tested according to more demanding standards. Intended 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 oxidative stability, higher wear and deposit protection. Implemented from 2004.

Oils for Spark-Ignition and Light Compression-Ignition Engines
A1/B1 - Oils additive against deposit formation on pistons, sludge formation, wear, and oxidation at high temperatures. Meet requirements for super light operation and fuel economy. Suitable only for certain engines.
A3/B3 - Oils intended for highly loaded spark-ignition and compression-ignition engines or for extended oil change intervals according to the engine manufacturer's recommendations.
A3/B4 - Oils for high-performance spark-ignition engines and compression-ignition engines with direct fuel injection, also suitable for use described in category B3.
A5/B5 - Highly stable oils intended for extended oil change intervals in highly loaded spark-ignition and compression-ignition engines. Meet requirements for super light operation and fuel economy. Suitable only for specially designed engines.
Oils compatible with catalysts – for spark-ignition and light compression-ignition engines
C1 - Oils designed forthe use of DPF (Diesel Particulate Filter) and TWC (Three Way Catalyst) catalysts in high-performance engines requiring low-viscosity oil with low SAPS (chemical limits) and a high temperature, high shear stability (HTHSV) viscosity greater than 2.9 mPa.s. 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. Oils extend the life 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 catalysts in high-performance engines. They extend the life of DPF and TWC catalysts. They are suitable only for specially designed engines.
Oils for diesel engines of trucks
E2 - Oils for general use for naturally aspirated and turbocharged engines, mildly to heavily loaded, with normal change intervals.
E4 - Oils providing excellent protection of cylinder cleanliness – against wear and soot. They are recommended for high-performance engines meeting Euro 1, Euro 2, Euro 3, and Euro 4 emission limits, operating under severe conditions, e.g. extended change intervals, according to the engine manufacturer's recommendations. They are suitable for engines without a particulate filter and for some engines equipped with exhaust gas recirculation or SCR (selective catalytic reduction of NOx) systems, according to the manufacturer's recommendations.
E6 - Oils providing excellent protection of cylinder cleanliness – against wear and soot. They are recommended for high-performance engines meeting Euro 1, Euro 2, Euro 3, and Euro 4 emission limits, operating under severe conditions, e.g. 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 especially 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 polishing. They further 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 emission limits, operating under severe conditions, e.g. 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 manufacturers' recommendations.
Note: Categories A2 and B2 are not included in the current edition. However, they are still valid in the last version, as long as they are recommended in the service books by 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 Catalysts Reduction) - selective catalytic reduction of NOx: modifying the composition of exhaust gases with urea (AdBlue agent = 32.5% aqueous urea solution)

Standards of automobile and engine manufacturers
Many automobile and engine manufacturers require engine oils to meet additional requirements not included in the methodology of previous classifications.


How to choose the right engine oil?
1. The first principle when selecting engine oil is to follow the instructions of the motorcycle manufacturer, contained in the manual.Each vehicle has its own requirements. Only the engine manufacturer (of the vehicle) can responsibly state which oil can be used. Practically no manufacturer recommends a specific brand of oil (as it contradicts competition laws in the European Union). Manufacturers (of cars) recommend oils according to the 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. For oils that are so recommended, the change intervals are then established.
2. For oils of the same performance specification, the same change interval is recommended.
3. If you do not have a vehicle manual, ask the manufacturer. Remember, the vehicle manufacturer does not recommend a brand of oil, but only 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 acceptable, but it is generally more expensive and does not bring much benefit.
5. If you are changing oil of low performance specifications (M5AD, M6AD) for a new oil with high performance, shorten the change interval for the first change (this will result in the 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).
