Pakistan’s hot climate can accelerate oil evaporation and increase engine wear, leading to higher oil consumption. High temperatures cause the engine to run hotter, thinning the oil and making it burn off faster. Additionally, fluctuating fuel quality and dusty environments can cause the engine to work harder, contributing to oil degradation and leakage. Regularly monitoring oil levels and using high-quality synthetic oils designed for extreme temperatures can help mitigate excessive consumption.
