Lubricants aren’t just about viscosity and performance—sometimes, their colour can tell a deeper story. While most people assume a darkening lubricant simply means it’s time for a change, the reality is far more nuanced.
🔹 Darkening Too Quickly? This could indicate oxidation, thermal degradation, or contamination with combustion by-products—particularly in engine oils.
🔹 Turning Green or Blue? This may point to coolant leaks in industrial or automotive applications, which can accelerate oil degradation and impact component longevity.
🔹 Reddish Tinge in Gear Oils? This could be a sign of excessive wear, particularly in high-load applications, where fine metal particles suspend in the fluid.
Lubricant colour shifts are early warning signals of potential system issues, contamination, or additive depletion. That’s why routine oil analysis isn’t just a maintenance add-on—it’s a crucial diagnostic tool for maximising equipment life and performance.
At Valorem Chemicals, we provide specialised lubricant additives designed to combat oxidation, extend oil life, and enhance performance, ensuring your lubricants stay in peak condition. Want to optimise your formulations? We’re here to help.
