When Should You Replace Your Engine Oil?
If you are unsure, a good rule of thumb regarding oil change intervals is to follow a 5,000 mile replacement schedule. However, breakthroughs in synthetic oil technology and other advanced Lexus innovations have made it possible to extend this interval.
Most Lexus vehicles now include an Oil Life Monitor (OLM). This system automatically monitors the oil life in your vehicle using an advanced algorithm. The system measures the engine oil life by three criteria: crankcase temperature, combustion chamber conditions (how the engine performs), and moisture (internal/external environment). The Oil Life Monitor will alert the driver with an indicator light, letting them know that an oil change is required soon.
It’s important to note that the Oil Life Monitor should serve as a helpful guideline for proper oil maintenance. Certain factors such as driving terrain, outside temperature, and individual driving habits can still impact oil life. For specific maintenance schedules and requirements for your Lexus vehicle, please consult your owner’s manual.
