Engine oil is the lifeblood of your vehicle's engine, ensuring that all moving parts operate smoothly and efficiently. However, it's not unusual for engine oil levels to gradually decrease over time. In this article, we'll delve into the factors contributing to engine oil consumption and the significance of regular oil replacement.

1. Oil Consumption

Engine oil consumption refers to the gradual reduction in oil levels within the engine. This natural process occurs as a small portion of the oil is burned alongside the fuel during the combustion process after lubricating the engine's components. This controlled oil consumption helps maintain engine efficiency.

Replacement Intervals

To uphold your engine's performance and longevity, it's crucial to adhere to a regular oil replacement schedule. The frequency of replacement depends on variables like driving distance and the time elapsed since the last change. The recommended replacement intervals may differ based on your vehicle's make, model, and usage conditions.

For example, for most Corolla models in various countries:

• Gasoline Engine: It is advisable to replace the engine oil every 10,000 kilometers (6,000 miles) or annually.
• Diesel Engine: Diesel engines typically require oil replacement every 5,000 kilometers (3,000 miles) or every six months.

However, it is imperative to consult your vehicle's maintenance schedule, as the recommended replacement intervals can vary depending on your specific model and usage.

Types of Engine Oil

Engine oil is available in various types categorized by API (American Petroleum Institute) rating, which reflects quality performance, and SAE (Society of Automotive Engineers) rating, indicating viscosity. To determine the most suitable engine oil for your vehicle, refer to your Owner's Manual. Using the correct engine oil is crucial for maintaining optimal engine performance and durability.

In conclusion, engine oil consumption is a natural process wherein a small amount of oil is consumed during engine operation. Regular oil replacement is essential to preserve engine health and performance. Adhere to the recommended replacement intervals specific to your vehicle model, and consult your Owner's Manual to select the appropriate engine oil type.
