Why Do Audi Cars Burn Engine Oil?

[CamillaAnn]

There are usually several reasons why Audi cars burn engine oil: 1. Use of unqualified engine oil: This refers to the inappropriate viscosity value of the selected engine oil. High-end cars generally use fully synthetic engine oil, and Audi cars are best suited for engine oil with a viscosity of at least 30, with the minimum requirement being 5W-40 oil. Using engine oil that does not meet the viscosity standard will lead to oil burning. 2. The engine block material is cast iron: Currently, most Audis that experience severe oil burning are models with 1.8T and 2.0T engines, which are mostly made of cast iron. Cast iron engines inherently consume more engine oil. Additionally, many European cars have cylinder walls designed with shallow mesh grooves to retain oil for lubrication and better break-in. Consequently, cylinder walls with mesh patterns hold more oil than flat cylinder walls, leading to higher oil consumption.
