The "Change oil" light should go on somewhere between 6,000 and 7,500 miles. Depending, of course, on your particular use.

SAVE the WAVE!
It is true that the oil life monitor cannot be reprogramed but the statement about what it takes into account is not correct.

The OLM "looks" at only two parameters
1) Number of engine revolutions since last reset
2) Oil temperature history since last reset.

Note that the OLM should not be used if the engine is operated in dusty environments or is frequently operated on short trips.

Lastly, the question about the oil life monitor and engine oils which can be used to extended drain intervals (Red Line, Amszoil and etc) is a good one.

I use Red Line and my rule of thumb is to change the oil at 150% oil life or once a year. That is, I run the engine until the light comes on, then I reset it and go to 50% oil life. You may need a scan tester to read the oil life monitor. I change the filter at every 50%

I have a 96 Lingenfelter Corvette. I am a Manager at a NAPA store and I tend to treat my car right and you make perfect sence. I sell Redline and use it in my car and that stuff is incredible!!!! I too change the oil once a year and replace it with a NAPA Platinum filter wich is WIX's top of the line and it runs great! It's a huge improvement using Redline! Sure it's expensive but if you have a Corvette you should pamper it?

Default Reset oil light

hey guys first day here and this got my attention, I just got a 96 LT 4 and first thing I did was check and change fluids. I did not see an oil light but I think it will come on when it needs to. I think this site is great I am also on Smokenvetes too they never said anything about lights. I will post my info as soon as I can. Thanks again

I figured out why I couldn't reset the oil change light. The problem is the Tact switches under the buttons in the driver information panel go bad. You can buy a whole new button panel for $220..... or if you have some soldering skills, you can repair it yourself for around $5-$7. I wrote up a nice tutorial with pictures on how to do it. Should I post it in here, or start a new How to thread?

I would suggest you start a "New Thread" with your question/issue.

In this way, you would bring attention to your specific problem.

Your "Service Engine" light is not the same as the "Change Oil" light.

The "Service Engine" light illuminates when there is a problem with the Emissions System.

2. Press ENG MET on the Trip Monitor. Then, within
five seconds, press it again.

3. Witbin 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
about ten seconds.

When the light goes out, the monitor is reset. If the
monitor doesn’t reset, turn the ignition off, then try
again.

YES!! The music does it! So nineties!! what is it?

I bought my '95 new in March '96 so Gangsta "Snoop Dogg" and Smashing Pumpkins " The world is a Vampire" works, although I usually play thru my CASSETTE deck Firehouse "Bye Bye Baby bYe Bye.. she wrote in a letter..." or Winger or GnR.
