Qué significan los números del aceite
In the world of automotive maintenance, understanding the numbers on motor oil bottles is crucial for ensuring the longevity and performance of your vehicle. The numbers on these bottles are not just arbitrary digits; they hold significant information that can help you choose the right oil for your car. So, what do these numbers actually mean?
The most prominent numbers on motor oil bottles are the viscosity grades, which are typically represented by a two-digit code. For example, you might see a bottle labeled “5W-30.” The first number, “5W,” refers to the oil’s viscosity at low temperatures, while the second number, “30,” indicates its viscosity at high temperatures. This system is standardized by the Society of Automotive Engineers (SAE) and ensures that oils meet specific performance criteria.
The “W” in the viscosity code stands for “winter,” indicating that the oil is suitable for cold weather conditions. The lower the number before the “W,” the thinner the oil, which allows it to flow more easily in cold temperatures. Conversely, the higher the number after the “W,” the thicker the oil, which provides better protection against engine wear at high temperatures.
In addition to the viscosity grades, some motor oils may also feature a third number, such as “5W-30 SN.” This additional number signifies that the oil meets or exceeds certain performance standards set by the API (American Petroleum Institute). The “SN” in this example stands for the latest API service category, which ensures that the oil provides optimal protection for modern engines.
It’s important to note that while viscosity is a critical factor in choosing the right motor oil, it’s not the only one. Other factors, such as the base oil used, additives, and the specific requirements of your vehicle’s engine, also play a role in determining the best oil for your car.
In conclusion, the numbers on motor oil bottles provide valuable information about the oil’s viscosity and performance characteristics. By understanding what these numbers mean, you can make an informed decision when selecting the right motor oil for your vehicle. Remember to consult your vehicle’s owner’s manual for specific recommendations and to ensure that the oil you choose meets the necessary standards for your car’s engine.
