What is the Low Ash Engine Oil Label?
2 Answers
Low ash engine oil is labeled as C2/C3-04. Engine Oil Selection: When selecting engine oil, it's not about choosing the most expensive one, but rather selecting the appropriate oil based on the characteristics of your car's engine and your usual driving habits. Engine oil can be categorized based on winter and summer use. For winter, the primary consideration is the low-temperature viscosity grade. In summer, due to higher temperatures, there's no need to select oil with a superior low-temperature viscosity grade. Engine Oil Grades: Engine oil grades are classified based on quality and viscosity levels, specifically for gasoline engines.
As an experienced driver, I remember how troublesome it can be to choose the wrong engine oil. The labeling for low-ash oil is usually clearly marked on the bottle, such as "Low SAPS" or "Low Ash," and you might also see ACEA C-series symbols like C2 or C3. Some brands directly use the term "DPF friendly." Why is this important? High ash content can easily clog the engine's particulate filter, especially critical for diesel vehicles, leading to issues with the exhaust treatment system and costly repairs. Nowadays, before selecting oil, I carefully check the packaging instructions to confirm it has specifications like API SP or similar labels, avoiding the temptation to use cheaper conventional oil. After switching to low-ash oil, the car runs more smoothly and reduces pollution emissions. For new car models or vehicles frequently used for long-distance travel, this is essential knowledge.
