This part is about the engine oil number meaning.

Engine oil numbers, also known as viscosity grades, indicate the oil's viscosity or thickness. The numbers represent the oil's behavior at different temperatures and play a crucial role in determining the oil's suitability for specific applications. Understanding the meaning of these numbers is essential for selecting the right oil for an engine. Here's an explanation of engine oil numbers:

The first number, such as 0W, 5W, or 10W, indicates the oil's viscosity at low temperatures. The "W" stands for winter, signifying the oil's performance during cold starts. A lower number indicates better cold-start performance, meaning the oil flows more easily at low temperatures. This ensures proper lubrication and protection during initial engine startup, which is critical for preventing wear and damage.

The second number, such as 20, 30, or 40, represents the oil's viscosity at high temperatures. It measures the oil's resistance to thinning out and its ability to maintain a consistent thickness and protective film under high operating temperatures. A higher number indicates a thicker oil, which provides better protection under extreme conditions, such as heavy loads or high operating temperatures.

For example, 5W-30 oil has a lower viscosity at low temperatures (better cold-start flowability) and a medium viscosity at high temperatures (suitable for normal operating conditions). On the other hand, 10W-40 oil has a slightly higher viscosity at low temperatures and a higher viscosity at high temperatures, making it more suitable for warmer climates or heavy-duty applications.

The choice of engine oil number depends on various factors, including the climate, engine design, and manufacturer's recommendations. Cold climates generally require oils with lower first numbers, such as 0W or 5W, to ensure proper flowability during cold starts. In contrast, hot climates or heavy-duty applications may require oils with higher second numbers, such as 40 or 50, for better protection under extreme temperatures or heavy loads.

Engine oil codes explained

This part is about the engine oil codes explained.

Engine oil codes, such as API (American Petroleum Institute) and ACEA (European Automobile Manufacturers' Association), are alphanumeric designations that provide important information about the performance, quality, and compatibility of engine oils. These codes help users select the right oil for their specific vehicles and applications. Here's an explanation of engine oil codes:
