How to Reset the Engine Oil Life Monitor on a 1990 to 1996 Corvette

Corvette models manufactured between 1990 and 1996 have an Engine Oil Life Monitor. The Engine Control Module (ECM) calculates the lifespan of the engine oil by measuring the engine’s RPM engine temperature over time. Resetting the Engine Oil Life Monitor after every oil change, regardless of whether the Change Oil indicator light illuminates or not is recommended.

Reset Procedure

  1. Turn the key to the ON position, but don’t start the engine.
  2. Press the ENG MET button on the Trip Monitor and release it. Then, within five seconds, press and release the ENG MET button again.
  3. Within five seconds of Step 2, press and hold the RANGE (1990 to 1991 Corvette models) button or the GAUGES (1992 to 1996 Corvette models) button on the Trip Monitor. The CHANGE OIL light will flash.
  4. Hold the RANGE or GAUGES button until the CHANGE OIL light stops flashing and goes out. When the light goes out, the Engine Oil Life Monitor is reset. This should take about ten seconds. Turn the ignition OFF and repeat the procedure if it doesn’t reset.
