Lightweight and Safe Tips: Rules for the Safe Storage of Lubricating Oils

In fact, people’s understanding of lubricating oils may be overly one-sided. Although lubricating oils are petroleum-based products, they’re neither toxic, harmful, nor flammable—so there’s really no need to “turn pale at the mere mention of oil.” Moreover, lubricating oils play an important role in many aspects of our daily lives; let’s stop looking at them through tinted glasses! Today, we’ll take you through some key knowledge about storing lubricating oils.

If the lubricating oil turns black, do you need to replace it immediately?

After being used for a period of time, lubricating oil tends to turn black. Some car owners mistakenly believe that this indicates the oil has severely deteriorated and thus replace it prematurely, leading to unnecessary waste. Typically, motor oils are formulated with detergents and dispersants designed to wash away the sticky film and black carbon deposits that accumulate on pistons. As a result, the color of the lubricating oil often darkens after some use—but this does not mean the oil has gone bad. So why does the color of lubricating oil turn black? Today, our editor will explain it to you.

Hydraulic Oil Contamination Control for Construction Machinery

Hydraulic oil serves as the working medium in hydraulic transmission systems, playing a crucial role in energy transfer, conversion, and control. At the same time, it provides lubrication, corrosion prevention, rust inhibition, and cooling for various components within the hydraulic system. Controlling contamination in construction machinery hydraulic systems ensures their normal operation, thereby extending the machinery's service life and enhancing its value. To effectively control hydraulic oil contamination, it is essential to select the right hydraulic oil: a. Choose high-grade anti-wear hydraulic oils; whenever possible, opt for hydraulic oils that match the original manufacturer’s specified brand and grade. Currently, there are numerous manufacturers and suppliers of hydraulic oils both domestically and internationally, and hydraulic oils vary significantly in quality—some are superior, while others are inferior or even counterfeit and substandard.

How do you determine whether a bearing can be reused? Pay attention to the bearing grease seal.

When performing regular maintenance, operational inspections, and replacement of peripheral components on equipment, the bearings that have been removed should be inspected to determine whether they can be reused or whether their current condition is better or worse than before. It is essential to carefully examine and document the condition of the removed bearings, including their external appearance. To accurately determine and investigate the remaining amount of lubricant, after taking samples, the bearings must be thoroughly cleaned. Next, inspect the raceway surfaces, rolling element surfaces, mating surfaces, and the condition of the retainer for any signs of damage or abnormalities. To decide whether a bearing can be reused, the China Lubricant Network recommends considering factors such as the extent of bearing damage, machine performance, the importance of the component, operating conditions, and inspection results.

A Brief Discussion on the Uncertainty of Base Oils

As the variety and availability of base oils on the market continue to expand, lubricant suppliers are also making ongoing efforts to better understand the differences among various types of base oils, thereby gaining a clearer grasp of the relative performance advantages each type offers. Giovanni Loizzo, Head of Base Oil Procurement at Lubrizol, highlighted several base-oil-related questions frequently raised by lubricant formulation developers when designing engine oils. Base oils are the primary components of lubricants, accounting for anywhere from 75% to 90% of the formulation in passenger car or heavy-duty vehicle engine oils. The properties of different base oils vary significantly from one another, which can have a substantial impact on the overall performance of the lubricant.

Trends in Heavy-Duty Engine Oil Development

Currently, heavy-duty on-road and off-road applications may continue to use the same engine oil specifications. However, at some point, it might become necessary to consider a dedicated off-road performance specification or develop unique products better suited to this market. This, in itself, presents certain challenges. Sometimes, the development of heavy-duty engines seems like that of a slow but steady turtle, whereas the development of passenger-car engines resembles that of a swiftly darting hare. Nevertheless, heavy-duty engine oils are steadily moving in the same direction as light-duty oils, with sulfur ash content emerging as a newer focus—particularly in off-road applications. Fuel economy is driving demand among Chevron’s heavy-duty original equipment manufacturers.

Here are two quick tips to help you identify genuine imported motor oil.

Attention, car owners: Currently, there are over 4,000 different brands of motor oil on the market, with widely varying quality. Although genuine imported motor oils are of high quality, it’s often difficult for ordinary consumers to tell them apart. We’ll show you a simple little experiment—just two easy steps—to help you easily identify genuine imported motor oils. First: Look! On the front and back of the original imported oil drum, the large label is entirely in English, with absolutely no Chinese characters. You can also check the barcode and the double-circle seal. (We’ll go into detail below.) Second: Burn! The term “genuine imported” means that the oil was filled into the drums overseas before being imported—both the oil itself and the oil drums are imported! Whether or not something is genuinely imported can sometimes fool people, though.

The “production + service” model is becoming the direction for lubricant companies.

In the post-pandemic era, as demand for lubricants declines, the “production + service” supply-chain model should become the development direction for domestic lubricant manufacturers and distributors. This was the key message conveyed at the second session of the second general meeting of the Shandong Province Lubricant Industry Association, held in Jinan on June 27. At the meeting, experts pointed out that due to the impact of the COVID-19 pandemic, both domestic and international demand for lubricants has declined. Specifically, domestic demand for lubricants is expected to drop by 7% to 10% year-on-year. However, China’s current oil-grade structure lags behind the evolving environmental standards for vehicles; thus, there remains considerable room for improvement in China’s oil-grade levels in the future, which could lead to an increase in demand for lubricants. Zhang Chenhui, deputy director of the Specialized Committee of the National Lubricant Enterprises Alliance, noted that, amid the decline in lubricant demand caused by the pandemic, lubricant companies need to innovate their production and sales models—shifting from a focus on quantity growth to one emphasizing quality enhancement and efficiency improvement. They should develop high-quality, specialized, and niche products, moving away from a single-product structure toward product diversification. At the same time, lubricant companies should also enhance the service levels provided by their sales networks. According to Da Jianwen, head of the expert panel of the Specialized Committee on Research and Application of Special Oil (Wax) Production Technologies, the impact of the pandemic will see domestic sales replacing imports, making it more important than ever to expand domestic sales channels. Nevertheless, in areas such as specialty oils—for example, oils used in vaccines and nuclear power—China still largely relies on imports. Therefore, domestic lubricant companies must persist in pursuing a path of differentiation, specialization, and high-end development, continuously enhancing the added value of their products to meet the new demands of the post-pandemic era.

Historical China VI Emission Standards and Their Requirements for Engines and Oils

What is China’s Stage VI Emission Standard? “China Stage VI” is the common nickname for the country’s sixth-phase motor vehicle emission standards. The Stage VI standard represents an upgrade over the previous Stage V standard. Compared to Stage V, Stage VI imposes significantly stricter limits on pollutant emissions. Specifically, for gasoline vehicles, the Stage VI standard reduces carbon monoxide emissions by 50%, cuts total hydrocarbon and non-methane hydrocarbon emission limits by 50%, and tightens nitrogen oxide emission limits by 42%. The Stage VI standard is divided into two phases: Phase 6A and Phase 6B. Phase 6A began on July 1, 2020, prohibiting the sale, registration, and licensing of vehicles that fail to meet the Stage 6A emission standards. Phase 6B, starting from July 1, 2023, will similarly ban the sale, registration, and licensing of vehicles that do not meet the Stage 6B emission standards. Currently, some regions have already begun implementing these standards ahead of schedule. How do the emission limits of Stage V and Stage VI differ? Compared to the Stage V standard, Stage VI—especially Stage VI B—significantly improves emission performance. Here’s a comparison of emission limits between Stage V and Stage VI: | Emission Type | Stage V | Stage VI A | Stage VI B | Reduction (%) | |---------------|----------|------------|------------|--------------| | CO (Carbon Monoxide) | 1000 | 700 | 500 | 50% | | THC (Total Hydrocarbons) | 100 | 100 | 50 | 50% | | NMHC (Non-Methane Hydrocarbons) | 68 | 68 | 35 | 48% | | NOx (Nitrogen Oxides) | 60 | 60 | 35 | 42% | | PM (Particulate Matter) | 4.5 | 4.5 | 3 | 33% | To meet the stringent Stage VI emission standards, newly launched vehicles—whether heavy-duty trucks or passenger cars—must adopt new technologies and components in their engines, such as turbocharged direct-injection technology (TGDI), exhaust gas recirculation (EGR), selective catalytic reduction systems (SCR), and particulate filters (DPF or GPF). These technologies are now widely used in engines. The new technologies and components introduced in Stage VI engines place special demands on engine oils: Turbocharged direct-injection technology can easily lead to early combustion at low speeds, requiring lubricants that can effectively inhibit sludge and carbon deposits around the combustion chamber and fuel injectors. Additionally, selective catalytic reduction systems and particulate filters contain precious metals like platinum, gallium, and palladium, which are prone to oxidation and damage; therefore, both fuel gasoline and lubricating oils must have low sulfur and low ash content. To ensure smooth operation and extend the lifespan of Stage VI engines, existing oil grades no longer meet the requirements, necessitating the development of higher-quality Stage VI-specific oils. As a result, the new SP-grade oil standard has been introduced. What is API? API stands for the American Petroleum Institute. The API rating indicates the quality grade of an oil, but it’s important to note that this quality grade does not directly reflect anti-wear performance alone—it represents a “comprehensive quality threshold,” including environmental performance. API ratings are categorized into two main groups: oils for gasoline engines, labeled with “S,” and oils for diesel engines, labeled with “C.” There are also universal lubricants that carry both “S” and “C” designations, compatible with both gasoline and diesel engines within a certain range. Gasoline-engine oils with “S” ratings include: SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN, and the newer SP rating. Why update the standards? In response to increasingly stringent national environmental regulations and energy-saving requirements, automakers are adopting various technologies—including engine downsizing, direct injection, turbocharging, reduced friction, and advanced exhaust treatment and combustion technologies—to further improve fuel efficiency and meet emission standards. For passenger cars, the trend in traditional powertrains has shifted gradually from larger displacement engines to smaller ones: 2.0-liter engines are being replaced by 1.6L, 1.5L, and 1.3L engines, and naturally aspirated engines are giving way to turbocharged engines. These changes all require higher-quality lubricants to provide adequate hardware protection and prevent operational issues, while also leveraging lower viscosity grades to enhance fuel economy. As a result, the lubricant industry faces ever-greater challenges, and updating lubricant formulations has become imperative. From the earlier API SA to today’s API SN, SNplus, and the recently announced API SP, each new standard brings higher requirements for various lubricant parameters. Currently, the mainstream grades in the engine oil market are API SN and SNplus. As the industry continues to evolve, oils of SL grade and below will gradually be replaced by other products. Meanwhile, the SP-grade oil, designed to meet the Stage VI engine requirements and align with national environmental policies, is poised to become the market’s dominant choice in the future.
