The "Change Oil " light comes on for a few seconds when you turn the ignition on. It will come on and stay on when it's time to change your oil in your 1992-93-94-95-96 Corvette, LT1 C4
The monitor uses oil temperatures and engine revolutions to decide when the oil is nearly worn out. The light is only a reminder, though. You should change your oil at the intervals recommended in your owner's manual, even if the "CHANGE OIL" light hasn't come on.
Be sure to reset the monitor when your oil is changed, even if the "CHANGE OIL" light didn't come on. If you do not reset the monitor, it will not work correctly.
To reset your monitor, take these steps:
1. Turn the key to "RUN", but do not start the engine
2. Press "ENG MET" on the trip monitor, Then, within five seconds, press it again
3. Within five seconds, press and hold "GAUGES" on the trip monitor. The "CHANGE OIL" light should flash
4. Hold the "GAUGES" button until the "CHANGE OIL" light stops flashing and goes out. This should take no more than ten seconds
When the light goes out, the monitor is reset. If the monitor does not reset, turn the ignition off, then try again.
Always use Mobile one 5W30, which is a synthetic oil, and change it per your owner's manual intervals. This will keep your Corvette running like new for a long, long time. And oh yeah, use a K & N or Mobil 1 oil filter for additional filtration protection.
