Chevy "Complete Care"

[duquephart]

Elsewhere I read that the first two oil changes are "free" but restricted to the first 12,000 miles or 12 months. On the web I find:

 

During your first 24,000 miles or 24 months of ownership (whichever comes first), we cover two oil and oil filter changes and tire rotations according to your vehicle’s maintenance schedule.

 

Sounds like the deal has been expanded. Am I missing something?

My understanding is that the free oil changes and time limit were reduced from 4 changes in two years to two changes in 1 year. My 15 had the 4 free changes.

Almost correct Don, they have 24 months/24K miles for the free oil changes now.

 

I never have used mine so I still have 4 available.

I thought it was 2 changes in the firrst 24 months? Is it 4?

[Thomcat]

Just bought a '17 Impala and like the '16 Silverado it is up to 2 changes per year for the first two years/24K miles.....so up to 4 total. My dealer said he would change at any mileage within that time frame and mileage regardless of what that engine killing OLM in the DIC reads, i.e. would even do the first two free oil/filter changes during the first year at 1K miles and again at 4K (which is what I routinely do on a new vehicle) if I wanted.

Is there any special deals with oil changes on GM certified used trucks? I had an oil change, the first one on my used 2014 Silverado with 25K on it and ended up being no charge. I figured i was paying for it and they must of made a mistake so I didn't ask why.

Don't understand why people would not use them. I have one left.I go every 6 months. I had 4 oil changes and tire rotation.

Didn't I read that by early 2017 that GM is switching to full synthetic Dexos 0-20 oil for oil changes done at a dealership? If that is correct, does the DIC oil interval display need to be changed as synthetic does not need to be changes as often?

[SilveradoSaver]

When I bought my '15 it was 4 oil changes in 2 years or 40,000 km's. I got my 4th and final one in at like, 39,900 km's haha. Didn't want to lose it!

One would think so! But, that would assume that there are engineers and computer programmers continuously updating the software to account for all changes of parameters feeding the algorithm upon which it operates and that sensors exist to monitor all possible parameters that will affect oil life....My .02......B$hit.

 

In order to truly operate effectively the OLM would need sensors to read those exact parameters which it does not monitor i.e. viscosity, organic/inorganic acid content, particulate content and more importantly the type and quality of oil added. Instead it "monitors"quality indirectly using the few available sensor inputs used innormal engine operation, i.e. engine running time, mileage, temperatures, speed, running time, oil pressure, engine temperature and attempts to indirectly "predict" what the condition and remaining lifespan remains in the oil. The code was probably written years ago and never updated since the reliability of the parameters it does use bear no relationship to the condition of what is actually in the crankcase.

 

The reason many mechanics refer to the Oil Life Monitors as "engine killers" is because many motorists take them for gospel instead using them as a general guideline for maintenance their accuracy being based upon assumptions for many parameters that are not being monitored.. For example, aside from the OLM having no idea what the acid types and levels, particulate content, or effective viscosity is present it has no idea whether the mechanic: threw in dino or synthetic oil..... used 8 qts. instead of underfilling 25% with 6 qts... whether it was 0W-20,10W-40, SAE 30, even if the correct grade whether specs are SL, SH or lower or bulk mystery grade re-refined from recycled oil......whether the filter (or the oil for that matter) was actually changed with the correct filter when the OLM was reset.....if there is coolant contamination from a leaking head gasket........etc., etc. In actuality the OLM has little more objectivity in ones determining when to change oil as using the presence of skid marks to indicate when to change ones underwear.

 

Common sense, knowing your usage patterns, the quality of the oil and filter and confirmation of the change is worth more than any blind obedience to the OLM. But there is one thing for certain - No engine has ever damaged by changing oil and filter too often, but many have died from not having changed them often enough.

I'm thinking of having changes at the dealer, at least initially, in conjunction with tire rotations. Every 6,000 miles sound reasonable?

[VeronaGMC]

I would assume you can take it back to any GM dealer for the 2 free oil changes?

Bought mine out of state etc...

[15 Z71]

I follow the oil life monitor on all my gm vehicles. My 06 silverado still running fine with 120,000 and wife's Acadia 65,000 running just fine. I have noticed that they all are towards 0% at about 6,000 miles or so.

Yep, any GM dealer/service center.

I reset the OLM every oil change. I don't remember what the percentage is when reset button it's never zero nor would I go that long. I changed oil every 5000 miles. It's easy to know when to change. My next is due at 75000. After that at 80000 it will be oil and filter along with tire rotation. Tires rotation every 10000 miles. Takes me an hour or so to do it all and I know it's done correctly every time.
