At some point, every driver experiences unexpected car troubles. While some issues are minor, others can escalate quickly if ignored—affecting safety, comfort, and repair costs.To help you stay informed and confident on the road, our experts have compiled a list of the most common vehicle problems, their likely causes, and what to do next.

When selecting the right grease oil, operating temperature range is one of the most critical factors to consider. Grease oil is composed of base oil, thickener, and additives, and its temperature tolerance depends on the properties of all three components.

In the daily use of lubricating oil, some users may notice visible fine impurities and sediments in the oil. These can include mechanical impurities such as sand, dust, metal shavings, fibers, and certain insoluble salts. In technical terms, sediments refer to all inorganic and organic substances in the oil that are insoluble in solvents (such as toluene). They are one of the specification indicators for medium and heavy fuels. Sediments may include both mechanical impurities and additives that precipitate at low temperatures.

Engine oil replacement is a critical part of vehicle maintenance. Choosing the correct oil for the season is essential, as temperature changes in winter and summer have a direct impact on engine performance and protection. Many drivers are unaware that engine oil requirements vary with seasonal temperatures—let’s break it down.

When it comes to keeping a diesel engine running smoothly, engine oil is its most reliable partner. Unlike gasoline engine oil, diesel engine oil must withstand long hours of high-speed operation, tough road conditions, and heavy loads. But despite its importance, many drivers still have doubts and misconceptions about diesel oil. Let’s take a closer look at some common issues.

Transmission systems are one of the most vital components of a vehicle, ensuring smooth power delivery and efficient performance. Just like the engine, the transmission requires proper lubrication to function reliably, and that’s where transmission oil comes in. Depending on the type of transmission, there are two main categories: manual transmission oil and automatic transmission oil. Both play an essential role in keeping the system running at its best.
