5 Signs It’s Time to Change Your Engine Oil
Routine oil changes are one of the simplest ways to protect your engine — yet many drivers ignore them until it’s too late. Here are five signs your car is due (or overdue) for an oil change.
-
Dark or Dirty Oil: Fresh oil is amber and translucent. If it’s dark and gritty, it’s full of contaminants.
-
Engine Noise or Knocking: Old oil loses viscosity, causing metal-on-metal contact.
-
Oil Change Light: Modern cars have sensors that alert you when it’s time for maintenance.
-
Excess Exhaust Smoke: Thick or dark smoke may signal oil burning inside your engine.
-
Rough Idling or Poor Performance: Dirty oil can clog internal passages, reducing efficiency.
How Often Should You Change It?
While many modern synthetics last up to 10,000 km, driving conditions matter. Frequent short trips, towing, or extreme temperatures shorten oil life.
At PD Oils, we recommend following your vehicle’s manufacturer interval and using premium-grade lubricants for maximum protection. Whether you need full synthetic or Dexos™ certified options, we ensure your engine stays protected — mile after mile.
