There are many myths around motor oils, which often mislead car owners and prevent them from making the right choice.
Myth No. 1
If the oil turns dark, it’s bad.
This is one of the most popular, yet erroneous, myths. In fact, darkening of the oil doesn’t necessarily mean it’s bad. Modern, high-quality motor oils, including PEXOL formulations, contain special detergent additives designed to keep contaminants suspended, preventing them from settling on engine parts. This active internal cleaning process is what gives the oil its dark color. This is a sign that the oil is truly working, protecting and cleaning the engine.
Of course, if the oil remains light-colored, it’s not always an indication of poor performance, as the degree of color change depends on many factors: mileage, fuel quality, engine condition, and operating conditions. The key is to trust the oil change recommendations and quality of the oil, not just its appearance.
Myth No.2
All motor oils are the same; it’s easier to just use the cheaper ones.
Experience consistently proves otherwise. Oils vary in composition, viscosity, additive package, and production technology. Choosing the wrong oil, especially in modern engines with high demands, can lead to reduced performance, increased wear, and even failure. However, high-quality PEXOL motor oil guarantees reliable protection and durability of the engine.
Myth No. 3
Oil loses its properties quickly—it needs to be changed every 5,000 km.
Modern technology has made significant advances in oil durability and stability. Car manufacturers, including BMW and Mercedes-Benz, recommend oil change intervals of up to 15,000 km or one year of operation, whichever comes first. However, real-world operating conditions may require adjustments to these parameters.
For example, when using PEXOL P5 5W-30 motor oil in a BMW 5 Series or Mercedes-Benz CLK-Class, the basic change recommendation is 15,000 km. However, given Russian climate and road conditions, as well as the specific nature of the oil (which in this case is medium-ash), the optimal interval is recommended to be reduced to 7,500 km to maintain maximum protection and stable engine performance.
