Debunking the Colour Myths A prevalent myth in the automotive world is that darker oil is inherently bad or that lighter oil is always superior.
What Causes Milky Oil Colour and Coolant Leak Issues
High-performance synthetic oils can remain lighter in colour over their lifespan due to superior thermal stability and resistance to oxidation, while poor-quality conventional oils may darken excessively due to rapid breakdown. This analysis moves beyond basic descriptions to explore the science behind the shade, the implications for engine performance, and how to interpret these visual cues accurately.
