Just a simple question, between all you guys out there, what is the normal miles that the computer reminds you of an oil change ? 3000, 4000, 5000, or what ever. Just wanted a ball park for my 04 burb 5.3.

 

 

 

thanks

It doesn't determine by mileage, but it goes by start-ups, temps, driving conditions...alot of variables go into it.

Right now I'm at about 20% life left after about 4500 miles since resetting/changing the oil. I've got synthetic in there so I'm not going to change it just yet. Not sure if the oil life is linear with engine revolutions or not.

On my 2002, which only has the 'change oil' message, I usually see it between 5000-6000kms, which is appromimately 3000-3600 miles.

I am having the same issue. I have 0% left running on Mobile 1 Syn with 4800+/- miles. To verify this, I will send a sample off to have analyzed. That way I will be able keep track of the actual miles and/or an accurate life span of it.

Here is the info on the OLM.

GM OIL LIFE SYSTEM...HOW DOES IT REALLY WORK

This is taken from the May 2003 GM Techlink publication

How often should engine oil be changed? 3,000 miles, 5,000 miles, 7,500 miles, 10,000 miles? Actually, all of these are correct, depending on operating conditions. Oil life is affected by many factors other than just miles driven. The type of driving, temperature, and engine load all play a part.

That’s why GM has developed the GM Oil Life System, an electronic watchdog that keeps track of all these variables and notifies the driver when it’s time to change oil. This system has become standard equipment on nearly all GM products since 2000.

Briefly, the Oil Life System is programmed with a certain number of engine revolutions. As the engine runs, this number is reduced until it reaches zero, and the Oil Life light or message comes on. But there’s more. Operating the engine under low or high temperatures, and under high load conditions subtracts (penalizes) extra revolutions, so the light comes on sooner. Changing engine oil according to actual need rather than an inflexible schedule provides several benefits.

First is simplified determination about when to change oil. No more decisions about normal conditions vs. severe conditions. Second is reduced operating costs for GM’s customers, who now have to change oil only when it’s needed. Third is minimizing the amount of used oil that must be disposed of. And fourth, engines will always be running with sufficiently fresh oil, for long life.

Traditionally, the vehicle maintenance schedule has been based on miles or time, while the oil change interval is now based on the GM Oil Life System.

When the change engine oil light or message comes on, it means that service is required on the vehicle. I should be serviced as soon as possible within the next 600 miles. It is possible that, under the best conditions, the engine oil life system may not indicate that vehicle service is necessary for over a year. However, engine oil and filter must be changed at least once per year, and at this time the system must be reset.

The OLM came on in my '05 iron block 5.3 last week at 5500 miles/150 engine hours.

6qts of Mobil 1 Truck & SUV and a new PureOne filter please.

mine came on when i changed my ecm. I reset it and I'll do my oil change at 3k. Then Ill reset it again and see where it takes me.

 

Can you reset the OLS if the change oil light isnt on, and how do you do it? the normal slam the gas 3 times in 5 sec?

One important thing to remember, is that the oil life monitor has no idea if you are running synthetic oil. It is programmed for Dino oil...

My '06 has 10K miles on the clock. OLM told me to change it the first time at about 7.5K miles. Right now its showing something like 60% oil life remaining. I use Mobil 1 Extended Service and K&N oil filters. This is the first vehicle I have owned where I will be relying on the OLM 100% for oil changes. No more 3mo/3000 mile oil changes for me.

      Oil Consumption

      By Chuck FB · Posted

      Ok that confirms the extra quart theme they are still going with which must mean they have noted some initial use more so then some engines and probably the bigger factor in all of this probably isn't the engine so much as its the insane distance or OLM that lulls a lot of the driving public into driving their new vehicle off the lot and not even doing one short interval oil change because the manufacturer doesn't say different and if the dealer follows that logic as well. Selling the rarely needing to be serviced concept seems to go over well with the public that wants to get away with as little as possible for dollars spent on the vehicles maintenance and I bet there are 3.0 engines just like other vehicles out there that never have their oil checked by the owner which goes back to why they probably felt the need to add that extra quart to avoid a costly theme.    Speaking of cutting filters open, it was probably over two years ago now that a youtuber who buys vehicles to do longer term reviews and pulls a fifth wheel through the mountains of Colorado on summer trips and that becomes part of the testing. Anyway he had a GM HD with the 6.6 gas and a Ford 250 with the 7.3 gas at the same time and of no surprise the Ford had more power etc but somewhere along the way in the few thousand miles he put on the truck, he changed the oil and was seeing glitter and cut open the filter and yeah, things were not looking spectacular. The truck about that time or soon after seemed down on power compared to what it had been and then threw some engine code, I expect the cam/lifters were failing and so he brought the truck back to the dealer and made some deal to get out of it as he knew it would sit for months waiting on a new engine as they were so backlogged at the time. He kept the GM for some time after that using it exclusively until he sold it after buying his next vehicle to do a review on. Definitely the filter can tell a story when things are starting to go sideways, but it would be a sickening feeling to cut it open and be faced with an ugly mess like that and be running a magnet through the pleats and the oil on the dirty side of the filter and see all the fines sticking to the magnet.    The dealer may have some ideas based on experience as to where that coolant smell is coming from, I would imagine if they can't find it but its smelling they would put dye in it to they could give it a run cycle and use the black light to see where it pops up, if its a hose connection, water pump, rad or even a head gasket etc.

      charm.li (website) has the vehicle-specific diagnostic procedure for that code, you can use to find what the cause of it is.

      Oil Consumption

      By KARNUT · Posted

      It’s at the point of amusement. I’m retired I have time. It’s fun seeing people try to convince me I’m using oil. I’m buying oil at the prescribed time. It gets drained and new goes in. Do I add in between, no. My oil doesn’t even get dirty in 5k miles. I don’t even see any drop on the stick. I check in the same place. All is well.
