Change Engine Oil message


KHE

Recommended Posts

I was scrolling through the parameters on the DIC of my '05 Deville and noticed the oil life was at 2%. I have not received the CHANGE ENGINE OIL message on the DIC. Does the message display at 0% or not at all? The '96-'97 Sevilles will display the CHANGE ENGINE OIL message on the DIC when the oil life percentage falls below 10%.

Your owners manual says this

CHANGE ENGINE OIL – 82: This means that the life

of the engine oil has expired. See Scheduled

Maintenance on page 6-4. After an oil change, the oil

life indicator must be reset. See Engine Oil Life System

on page 5-17. See Engine Oil on page 5-14 and Oil

Life Indicator on page 3-79 for more information.

and this on 5-17

When to Change Engine Oil

Your vehicle has a computer system that lets you know

when to change the engine oil and filter. This is based on

engine revolutions and engine temperature, and not on

mileage. Based on driving conditions, the mileage at

which an oil change will be indicated can vary

considerably. For the oil life system to work properly, you

must reset the system every time the oil is changed.

When the system has calculated that oil life has been

diminished, it will indicate that an oil change is necessary.

A CHANGE ENGINE OIL message in the Driver

Information Center (DIC) will come on. Change your oil

as soon as possible within the next 600 miles (1 000 km).

It is possible that, if you are driving under the best

conditions, the oil life system may not indicate that an oil

change is necessary for over a year. However, your

engine oil and filter must be changed at least once a year

and at this time the system must be reset. Your dealer

has GM-trained people who will perform this work using

genuine GM parts and reset the system. It is also

important to check your oil regularly and keep it at the

proper level.

If the system is ever reset accidentally, you must

change your oil at 3,000 miles (5 000 km) since your

last oil change. Remember to reset the oil life system

whenever the oil is changed.

But it is not clear when it states to change the oil

I would go by the DIC. On my 1997, if you miss the message, it will come back after you shut off the car for awhile and restart it, or if you press the "Reset Info" button while the display is on a non-resettable quantity like average mileage.

I haven't received the CHANGE ENGINE OIL message yet and it is at 1% as of this morning. The owner's manual didn't specify at what percentage the message would display. I'll see if it comes on at 0% - at any rate, way, I am going to change the oil very soon.

My '97 came on at 10%. This car has never gotten that low so I don't know. I'm surprised that GM changed it from the 10% warning. What do you want to bet the tree huggers are behind it.

You could be right those wack-jobs have way too much power as far as I am concerned. Mine is at 1% right now. Even at 0%, there is a safety factor in the oil life - I just want to see if the CHANGE ENGINE OIL message will appear. My guess is that at 0%, it will appear on the DIC.

I hope that is not true. The fact that the OLM gets owners away from the 3000 mile change (GUESS) interval, should be enough for the ecoenvironmentalists, given that the change interval is much greater than 3000 miles unless you are driving exclusively local short trips.

If I were GM I would have pushed that issue, that the OLMs average change interval is about 6000 miles, up 100% from the 3000 mile interval that the oil change shops PUSH and the OLD standard

Something tells me you will not get that message. Mine would appear at 10% and stay there.

UPDATE: The oil life monitor hit 0% yesterday and when I started the car this morning, there was no message. I wonder why the CHANGE ENGINE OIL message was eliminated???

Update, I called GM customer assistance. Spoke to a nice lady who said that it SHOULD tell you at 10%, she told me that she read it in the owner's manual!!! I said I looked at an on line copy of the owners manual and did not see it, and Kevin you looked also and didnt see it.

She told me what she was reading said it should come on

She advised taking it to the dealer that is might be something that a tech could activate after I suggested that maybe just maybe, this message was suppressed so that ON STAR could handle the deed, via email, etc..

Just looking out for you Kevin, see what you find out

This is interesting.

I remember on my 2000 DTS it would come on after 10% but towards my last changes it would get down real low without warning me and I would change it anyway.

Guess we should figure out what part of the computer calculates, what sensors it reads and how it figures out when it needs changed.

My 96 fleetwood it warned me real early this year to change the oil but hasnt since. It just has a dummy light for that. But supposedly it calculates it. So here I am probably 9 months and 6k miles since a change and no light. I dont know if its broke or if its really not time to change it yet?

I just checked my 1997 FSM and it says that the CHANGE ENGINE OIL message comes at 0%; we know that's wrong, but I personally have never let my go that long. We know it's 10% because lots of people have checked their data display after getting the message and it say s10%.

I looked for an override or some other condition and did not see one. There don't seem to be any overrides for the PCM available through the A/C interface. I suspect that this message might be disabled with a Tech II but I have my doubts about even that.

I would check for OBD codes. Also, I would reset my oil life counter and watch it this time, and see if it happens again. If it does, I think that a checkup with a Tech II might be in order because one malfunction of the PCM might not be the only one.

So as to not confuse or hijack this thread, I started a thread on the Oil Life Monitor

Here is an odd one, this was in my 96 manual, I would think this is a mis-print OIL LEVEL?????? I never saw this info before, it does not make sense

The DIC may display a CHECK OIL LEVEL message.

Always keep a written record of the mileage and date

when you changed your oil. For more information, see

the Cadillac Maintenance Schedule booklet. If you see

CHECK OIL LEVEL, it means that you have less than

10% of the oil life left and you should consider

changing your engine oil. If you see CHANGE

ENGINE OIL, it means the oil lifei s gone and you

should change the oil right away

This was also in my manual

CHANGE ENGINE OIL - 82: This means that the life

of the engine oil has expired and it should be changed

within 200 miles. See “Engine Oil” and “Filter

Recommendations” in the Maintenance Schedule. After

an oil change, the Oil Life Indicator must be reset. See

“Oil Life Indicator” in the Index on how to reset it.

Thanks - I'll see what I can find out but paying the stealership $100 to activate the feature isn't on the top of my list...

The Fleetwoods canculate the oil life in the same manner as the FWD cars - they just don't display the percentage on the dash. When the oil life drops below 10%, the CHANGE OIL light illuminates.

6,000 miles can be well within the range allowed with OLM if you do mostly highway driving.

nah, all city.

So Ill probably go ahead and change it anyway but you know what I mean when I say I wish I knew when it was going to come on? Cuz if I change the oil then in a month it pops up then I have to reset it and now its always going to be off of when the oil actually needs changed :wacko:

6,000 is way past due for a city driving. I would not rely on OLM , just keep the records and change in some 4,000 miles.

I too find it hard to believe that the message was eliminated. If that's the case, what's the sense in equipping it with an OLM?

The OLM is there to prevent inadvertent abuse of the car. I never wait for the OLM to warn me. I do use it, though. I check it occasionally through the computer readout and change my oil when it reads 50%. I have never let it get below 40%.

That's a good news. Nevertheless, if the message is displayed at or below %0, the OLM alert is useless. I would disconnect the battery (the both cables for the heck of it) to reset the computers (if there is something to be reset), and keep a log of oil life versus mileage and date for reference and analysis.
