The quality and grade of engine oil plays a crucial role in controlling oil consumption:

Correct oil grade: Using the recommended oil grade for the Prius, typically 0W-20 synthetic oil, ensures proper lubrication, reduces friction, and minimizes oil burning.
High-quality oil: Premium, fully synthetic oils maintain their viscosity and performance over time, protecting the engine better than conventional oils. Low-quality oils can break down faster, contributing to higher oil consumption.

In Pakistan, where temperatures can be quite high, using the recommended oil grade and changing the oil regularly is important for optimal engine performance.
