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, there are also changes in operating temperatures. For effective lubrication, it is essential that the viscosity of the oil changes as little as possible with temperature. This dependence is characterized by the so-called viscosity index. The higher this index, the lower the dependence of viscosity on temperature changes. The specifications for characterizing the viscosity properties of motor oils is based on SAE (Society of Automotive Engineers, USA). This standard uses 6 winter grades marked by a number and “W” (for Winter) and 5 summer grades marked by 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 indicates the behavior of the oil at low temperatures (e.g., SAE 15W oil has a minimum pumpability temperature of -25 °C).

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

Performance Category
They characterize both immediate and long-term properties of engine oil under various forms of operational load. Different properties are evaluated, such as oxidative stability, volatility, wear protection, sludge 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 (Association des Constructeurs Européens d'Automobile, EU)
manufacturer corporate standards for engines and vehicles (VW, MB, MAN, VOLVO, TATRA)
MIL-L classification (U.S. military standards)
other classifications (e.g., ILSAC)
Currently, the most significant specifications are those of API, ACEA, and the corporate standards from 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 The CCMC classification is already outdated and is only mentioned temporarily.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 usage into oils for gasoline (petrol) engines, marked with the letter "S" (from English: Service), and oils for diesel (compression ignition) engines, marked with the letter "C" (from English: Commercial). Most oils can be used for both types of engines and are then marked 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, manufactured between 1940 – 1950.
SB - Oils with additives to prevent deposits for engines manufactured between 1951 – 1963.
SC - Oils with additives to prevent deposits and low-temperature sludge for engines manufactured between 1964 – 1967.
SD - Additized oils with detergent and dispersant additives for engines manufactured between 1968 – 1971.
SE - Oils for heavily loaded engines manufactured between 1971 – 1979.
SF - Oils for highly loaded engines manufactured between 1980 – 1988.
SG - Oils for engines manufactured between 1988 – 1993 that meet the strictest requirements for minimizing wear and deposits.
SH - Oils with the same properties as SG but tested according to more stringent standards. Designed for engines manufactured in 1996 and older.
SJ - Oil for engines manufactured in 2001 and older.
SL - Oils exceeding API SJ with increased fuel economy and extended service intervals.
SM - The highest quality oils exceeding API SL with increased oxidative stability, better wear protection, and sludge resistance. Effective from 2004.

Suitable for engines without particulate filters and for most engines equipped with exhaust gas recirculation, or SCR systems, as per manufacturer’s recommendations.
Note: Categories A2 and B2 are not included in the current edition. However, they remain valid in their latest version as long as manufacturers recommend them in service manuals.
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: treatment of exhaust gas composition with urea (AdBlue reagent = 32.5% aqueous solution of urea)

Automaker and engine manufacturer standards
Many automakers and engine manufacturers require engine oils to meet additional requirements not included in the methodology of previous classifications.


How to correctly choose engine oil?
1. The first principle when selecting engine oil is...

1. Follow the manufacturer's instructions for the motorcycle, as contained in the manual for each vehicle. Only the engine manufacturer (of the vehicle) can responsibly state which oil can be used. Practically no manufacturer recommends a specific brand of oil (this contradicts the competition laws in the European Union). Manufacturers (of automobiles) recommend oils according to performance specifications such as API SH/CD, ACEA A3, VW 505.00, MB 229.1, and viscosity specifications SAE, such as 15W-40, 10W-40. For oils thus recommended, oil change intervals are then specified.
2. A uniform oil change interval is recommended for oils of the same performance specification.
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 acceptable, but it is usually more expensive and does not bring much benefit.
5. If you are changing oil of low performance specifications (M5AD, M6AD) for new oil of high performance, shorten the oil 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).
