W24 Engine Oil Change Reminder Message Reset

[Knightly]

I have a 2007 Itasca with a W24 Workhorse Chassis. I do all the routine maintenance as per the owners manual. Upon completing an oil change, I reset the computor as per the instructions in the owner's manual. My problem is that the instrument cluster will randomly indicate that the engine oil needs changing. It does not appear to be synchronized with the Scheduled Maintenance Services. Is it possible to synchronize the cluster warning with the actual service schedule?

Derek, When your reset the OLM it will accumulate data and trigger a follow on event when it's scheduled to. I have not heard that the OLM DTC can be set to coincide with Scheduled Maintenance Services that are being applied to your vehicle.

Here is the service manual for the 2007 Actia Instrument Cluster...perhaps it may help you!

I'm sure Mike is correct. It is definitely more than an alarm clock which only measures time, or an odometer which only measures distance travelled.

We have been told here in the forums and elsewhere that the GM Oil Life Monitoring system contains a set of alogorithims which calculate "when" an oil change is required based on a set of actual engine conditions such as time at idle, RPMs, min & max temperature achieved, operating hours, etc. It does not have the ability to "test" the oil, or verify any oil quality issues, but rather is a calculation of what the oil's condition should be (assuming the recommended oil and viscosity is being used) after being used under the moinitored operating parameters.

However, because it is "only" a calculation of a theory about the oil condition, I certainly do NOT wait on my OLM to tell me "when" I need to change my oil. IMO, fresh oil and a clean filter is one of the cheapest forms of PM. I won't drive mine more than 4,000 miles between oil changes, and I've had to change my oil while overnighting in a CG several times. Ed

Thanks to Mike, Jon and Ed for the information. I now have a much better understanding of how the Workhorse engine instrument cluster functions.

Merry Christmas,

Ed, I had a 10 minute " expanation" from my Honda service writer the other day on this subject. I " think" he was trying to say, what you have said here, but not nearly so well.. Thanks.....rgr...
