The fact is, engine oil oxidizes over time, losing its operational properties and thus providing poor lubrication for the engine. Additionally, the oil’s oxidation process is significantly accelerated when used in the engine, as it constantly collects and accumulates combustion products from fuel, contaminants, and wear products from engine parts, all while being subjected to high temperatures. To prevent engine damage resulting from oil degradation, all car manufacturers recommend oils of a certain quality according to APIACEA standards, specifying viscosity and the desired replacement interval. Adhering to the recommended oil change interval ensures the timely removal of accumulated contaminants and wear products from the engine, providing optimal lubrication with fresh oil. Vehicle operating conditions also play a crucial role in determining the oil change interval, including driving style (moderate or aggressive), usage conditions (urban or rural driving, terrain), and vehicle load. Each of these factors can influence the oil change interval to varying degrees.
During engine operation, it’s important to monitor the oil’s condition and level. However, it’s crucial to remember that oil darkening doesn’t always indicate wear and tear. If the oil gradually darkens without changing its consistency (thickening or separating into different colors), it typically indicates normal operation. On the other hand, if the oil becomes thick and resembles fuel oil, it may indicate excessive soot content, coolant contamination, or poor oil quality.
Hartol engine oils are available in various SAE viscosity ranges and meet the strictest API/ACEA requirements. This ensures that you can always select a high-quality and suitable engine oil for your car or equipment from the Hartol range.
