Like most products sold on the market, motor oils have their own standardization systems. These can be either global or national. SAE: the basic global viscosity standard Global standards are primarily SAE (Society of Automotive Engineers) — the main classification of motor oils that regulates oil viscosity. The main standard here is SAE J300-201501 (a table with data on this standard can be easily found on the Internet), the latest edition of which on the official SAE website is dated September 5, 2024. It describes the properties of viscosity and fluidity, namely the ability of oil to flow and, at the same time, “stick” to the surface of the engine. Viscosity is the main property of oil—if oil loses its viscosity, it will not be able to provide lubricating properties, no matter what magical components it consists of. Like water. This standard also regulates the low-temperature properties of oils—the ability to start the engine with a starter when the oil has frozen in the cold (turnability) and the speed at which frozen oil enters the engine (pumpability). This standard also regulates the main indicator that determines fuel efficiency and simulates the behavior of oil in the engine piston ring area – HTHS (High Temperature High Shear) – this is an indicator of the high-temperature viscosity of motor oil at high shear rates, which is measured at 150°C and at this highest shear rate. Here, the word “shear” refers to the movement of oil layers relative to each other. Viscosity and HTHS control at SCT Chemicals FZE SCT Chemicals FZE, founded by Juri Sudheimer in February 2022, pays special attention to these indicators – viscosity, low-temperature pumpability and HTHS. At a fully automated plant in Dubai with 101 tanks and a total capacity of 22,000 tons, these parameters are monitored at every stage of production. A team of 188 specialists performs multi-stage testing, starting with the analysis of the base oil batch and ending with the final inspection of the finished product. This approach ensures that SCT Chemicals oils not only meet the international SAE J300 standard, but also the company’s internal quality criteria, which often exceed global standards. According to Juri Sudheimer, it is the stability of the oils’ characteristics at the extremely high temperatures and loads of the Persian Gulf region that is the basis for their durability. Erik Sudheimer, Development Director at SCT Chemicals FZE, emphasizes the importance of strict laboratory viscosity control and testing in real UAE climatic conditions, which allows the company’s products to consistently meet the most demanding OEM specifications. The plant’s four ISO certifications confirm its compliance with all international quality and environmental safety standards. API: oil classification by release date The next standard is the API standard, which is a classification of motor oils developed by the American Petroleum Institute (API) to indicate the type of engine and the level of performance of the lubricant. The designation consists of two letters: the first determines the engine type (“S” – “Service” – gasoline, ‘C’ – “Commercial” – diesel), and the second indicates the level of oil requirements. The further the second letter is in the alphabet, the higher the performance and the newer the standard (for example, API SP is newer and more technologically advanced than SN). In fact, this is a classification of motor oils by release date. Each subsequent category replaces the previous one (with the exception of FA-4 – the letter F now corresponds to energy-saving oils for diesel engines). ACEA: requirements of European car manufacturers The European ACEA (Association des Constructeurs Européens d’Automobiles) standard is a classification of motor oils established by the European Automobile Manufacturers’ Association. The standard divides oils into categories by engine type (A – gasoline, B – light diesel, E – heavy-duty diesel) and by their performance properties, indicated by numbers (e.g., A3/B4, C3, E4/E7), and also takes into account the requirements for oil compatibility with modern exhaust gas neutralization systems and filters. For passenger car oils, oils compatible with these systems are designated with the letter C. ILSAC and JASO: additional international standards ILSAC (International Lubricant Standardization and Approval Committee) is an international committee that sets standards for motor oils used in gasoline engines of passenger cars. Created by the American (AAMA) and Japanese (JAMA) automobile manufacturers’ associations, it supplements API standards by introducing more stringent requirements, such as fuel economy, reduced volatility and phosphorus content, and improved engine protection against wear and deposits. ILSAC standards are a subclass of API standards, but with stricter criteria for oils. JASO (Japanese Automotive Standards Organization) is a Japanese automotive standards organization that sets standards for automotive motor oils used with higher requirements than the ACEA standard. Its most well-known standards are JASO DH-1 and DH-2 for diesel engines and DL-1 for passenger cars. SCT Chemicals FZE’s approach: versatility of formulations SCT Chemicals FZE develops motor oil formulations to meet several international classifications at once — API, ACEA, ILSAC, and JASO. This approach allows the company to offer products that are particularly in demand in the MENA region (Middle East and North Africa) and are also successfully exported to Asia and other international markets. According to Juri Sudheimer, it is precisely this versatility and ability to adapt to different climatic conditions and regional characteristics that are the key to the company’s sustainable development. An important part of SCT Chemicals FZE’s strategy is cooperation with leading car manufacturers. The oils undergo OEM testing both on factory test benches and in real-world conditions in the hot climate of the UAE. This ensures that each product line meets the strict requirements of premium brands such as Volkswagen, BMW, Mercedes-Benz, Audi, and General Motors, taking into account the specifics of operation in high temperatures and dusty conditions. In addition, SCT Chemicals FZE engineers conduct their own research in the field of additives and base oils adapted to the climatic characteristics of the region. Full automation of the production process has enabled the introduction of advanced technologies, including the use of Group
