Dealer Recommended Wrong Oil

steveg241 said:

So I went in for my 7500 mile oil change and the dealer recommended Mobil Delvac 1 ESP as the synthetic oil for my car.

They were very understanding and used my Mobil 1 ESP 5w30. Seems the education still isn't getting through.

I was also told by one employee that I would void my warranty if I used a non-Dexos 2 oil. Not really confidence inspiring but they were willing to listen to my concerns.

I hope they get this figured out. Officially there is no listed synthetic oil for the Cruze in the GM parts manual.

Looks like a nice oil other then the ash is at 1%... 0.8% or less is the sweet spot. Too bad, I expect ignorance from someone off the street but from the service department of the company selling the product...unacceptable under any circumstance. If you're not 100% confident, ask someone else who is or take the time to make a call/look something up....Like we've all done

This is why I want to just do the oil changes myself but my dealer has a deal if I go to them for maintenance then I get free tires for life. When it does come time for my service I am going to print everything out that they car should have done to it and hand it to the service manager.

Is Mobil 1 Dexos 2 approved? I know it's Dexos 1.

Any time anyone tells you that doing something will "void" your warranty give em the bird. The magnuson moss act of 1975 dictates that no manufacturer can void a warranty for altering a car, and only if there is undeniable proof that a modification caused a malfunction can it be denied as a warranty claim. If your window switch goes out and is covered under warranty and they tell you they wont fix it because you use the wrong oil, get a lawyer you have free money waiting for you in the form of a lawsuit.

AGREED! They would have to prove that the oil caused any failure (which it won't) to deny a warranty claim.

Yeah...I'm worried about my first service on the Cruze diesel. I'm really hoping I can find a savvy dealership to do the work. Printing out what the specs are is a good idea. Where can you find that kind of information? It would be great if it were printed in the user manual.

Y'all can come to were I work. But when a diesel comes in I don't know what goes on up front but I make sure the right oil comes in for it even if they have to come back later in the day. I guess one of the perks of being on here I know a little bit about the cruze's

Also the dealer didn't know to drain the fuel filter of water or to fill the DEF tank.

This is so painful and a huge waste of my time. All the dealer had to do was look at the required services for the service before I got here.

If you don't know diesels, do not buy a Cruze Diesel. I feel bad for all the people who will have issues because the dealers are not trained and GM is doing a poor job as well.

People will probably end up with water in the fuel filter issues and run out of DEF in the middle of a service interval and have no idea why.

How are we supposed to take GM seriously if they cannot even coordinate something this simple? Honestly love the car but there has been so much BS and confusion associated with it and it's really leaving a bad taste in my mouth for GM. All this has already changed my better halfs mind from even considering a GM vehicle to ensuring the next car will be a Volkswagen or Audi.

Seriously veg with all of the unbearable troubles you've expressed with your Cruze diesel ownership experience I'm astounded that you simply haven't dumped it for something, anything, better.

It's not problems with owning the Cruze diesel. It's problems getting it serviced at dealerships. I had to remind them to use dexos 2 oil when I got my first oil change. The dealer only had 24 quarts of it and had to wait an hour to get the oil filter from another dealer.

Now, your service manager is right that you could void your warranty using oil that's not dexos 2 approved, no matter the specs (although if the specs are better then if it went to court I'd have to think you might win). The manual specifically states to use only dexos 2 approved.

I don't trust getting service done at dealerships, so I always remind them to use the correct product or bring my own

going in tomorrow for my second oil change. I made a pretty big production on my first oil change. I placarded the vehicle in multiple places "dexos 2 only". This time when I called to schedule my visit the dealer called and told me they have dexos 2 in stock. I will still insist on being provided with an empty bottle of oil as proof. Wrong oil will prematurely clog up your DPF.

It really is just dealing with the dealer. The car has been great so far. I just would like a dealership that sold the car to know something about it.

I know the manual says Dexos 2 but they can't require you to use something that is licensed. The oil I'm using meets ACEA C3 specs which is what the manual says to use if you can't use Dexos 2.

I probably won't buy another unless GM can turn around the knowledge and education aspects. However I'm keeping this unless there are mechanical issues. I can work around the mis-information and knowledge gap.

Yeah. I don't think I should have to tell the dealer what oil to use. They should know to begin with. With this new dexos 2 and Cruze diesel there should have been education for the service side before cars even hit the lot.
I don't think wrong oil will clog up the dpf prematurely. It's going to clog your engine with soot. It is my understanding that the dexos 2 oil is to prevent soot from sticking to engine parts. Thanks to the government we have to have an EGR system recirculating soot back into the engine. Such a brilliant idea

I think we are both right. Soot is bad for the engine. Ash is bad for the DPF. Dexos to is good for both issues. DPF, SCR, EGR, DEF,ETC. I wish we could get rid of all these acronyms. Ash Accumulation in Diesel Particulate Filters

Yes. Just left my car at the dealer for a oil change and some warranty work. Scared to death the wrong oil will be used. The parts guy insured me when they come for the filter he will give them the right oil. I can only hope.
