Audi Q3 oil filler port: The yellow (or red) pull ring on the left side of the engine is the oil filler port. Effects of overfilling engine oil: Overfilling engine oil can affect the operation of the three-way catalytic converter. Additionally, due to increased oil pressure, it may cause certain damage to sealing components. It also leads to intense agitation of the crankshaft and connecting rod big end during engine operation, which not only increases internal power loss but also results in more oil splashing onto the cylinder walls, causing oil burning and exhaust emission issues. Functions of engine oil: The engine is the heart of a car, containing many metal surfaces that move against each other with high speed and under harsh conditions, with operating temperatures ranging from 400 to 600 degrees Celsius. Under such severe working conditions, only qualified lubricating oil can reduce the wear of engine components and extend their service life.
