Mobil 1 extended service oil

Darwins Child · 04-24-2016, 11:32 AM

Thanks for the advice.

Although I think that changing oil every two years with the extended-service oil would be fine, as I have in all my vehicles of the past, I'll continue to be overcautious and change oil once per year. For our summer-only Z, this will be at the end of the last ride of the driving season with regular-service Mobil 1.

Thanks again.

I think some commenters need an update for our 3K km per driving season Z.

I hate quoting myself, but I already conceded defeat on the two-year interval in my post #13 earlier in this thread:

Then, a few posts later, the logic of a 1-year change for a summer-only vehicle:

For a summer-only, low-km vehicle, this is patently ridiculous for some very good reasons.

In Edmonton the winter's are normally at least 6 months long, and for summer-only Z drivers this means that the vehicle will not be operated for 6 months or more.

With the above in mind, let's say the owner attempts to not exceed the Nissan-mandated 6-month oil-change interval. So the owner changes the oil in say mid April and, in our case, after driving 3K km or so, 6 months later in mid October. Sounds very reasonable, right?

But what happens next April, after the car has been sitting all 6 months of winter? Just to satisfy Nissan's requirement, am I actually supposed to go out to buy (and get a dated receipt for) a new filter and new oil, then drain the "old" new oil out of the vehicle, trash the "old" new oil filter, then screw on the new new oil filter and pour in some more new new oil?

Again, for summer-only Z drivers, and there must be millions of them, Nissan's requirement is ridiculous and should be fought. IMO, the oil change requirements for mileage might remain the same, but the time interval must be changed to 1 year. That is, 8K km (5K miles) or 12 months, whichever comes first.

I'll be heading to the local Nissan dealer to buy an oil filter in the next day or two. I'll discuss the matter with the service manager and report back what he has to say. I can't believe that he's going to stand there with a straight face and tell me that it is necessary for Edmonton's summer-only, low-km Z owners to go through that ridiculous, wasteful procedure.

If contamination of the new oil during the winter in which the car is not operated is of concern, one could in the fall drain the old oil for a few days, remove the old filter and install the new filter and plug Then just wait until the beginning of the driving season to remove the plug to drain any old oil that slowly dripped down over the months, reinstall the plug and pour in the new oil.

Then you're sitting there with undiluted "bad" oil on all the parts all Winter.

Yes, one can get away with longer than 6 months oil changes. Between the materials used in newer engines and the great advances made in lubrication, corrosion is not as big of a deal as it used to be. BUT ... neither materials nor oils are perfect and there will be a significant amount of corrosion if you don't change the oil often.
In your situation, changing your oil at one year intervals probably won't do enough harm to really worry about. But why take a chance? Oil and filter aren't that expensive. As someone said before, it's cheap insurance.

I encourage you to send off samples of your oil after each change to Blackstone Labs. It only costs $25 and they'll even send you free materials to ship the oil. They will give you straight up facts about the quality of your oil and the amount of contaminants.

You said you've done two year OCIs in all your previous cars. I still question what makes you think that a two year interval is ok. It is very likely that your other car manufacturers recommend 6 month minimum OCI just like Nissan. I bet its not 2 years

Also, I read your logic for 1 year oil changes ... Go read the Bob The Oil Guy forums and you'll quickly realize it's far more complicated than your explanation. FWIW, I have seen manufacturer recommended 12,500mile/1year OCIs recommended on some vehicles in recent years, but they were not high performance sports cars.

the 335 recommended a 16000km interval on their manual...not a super high performance but nothing to baff at either. still way too much (10k mile) interval.

BMW had actually recommended a 15,000 mile / 24 month interval before reducing it to every 10,000 miles / 12 months. I wonder why they changed it ...

I have to apologize for not being clear in an earlier post. I even re-quoted it without realizing it.

I thought that the last phrase with the word "continue" would make clear that I've always changed in our previous vehicles at a 1-year interval, but I guess I wasn't clear enough. I must admit that the phrase "as I have in all my vehicles of the past" could be understood to apply to the first part of the sentence. It does not.

So now I'll say that I've never changed any of our present or previous vehicles' oil at a two-year interval. In fact, for our year-round Outlander I have changed oil twice in one year when we have put on more than normal kms.

I'm glad to hear that you are not doing 2 year oil changes. I change the oil on my Z 3-4 times a year based on mileage alone.

Also, my oil changes cost ~$30, so there's really no reason to try and extend the life of the oil. I just picked up 5 quarts of Mobil 1 at Walmart for $22.88 the weekend before last.

If you're worried about changing your own damn oil and having Nissan break out of warranty if something arises, you may want to get a freaking honda Odyssey. Changing any fluids regardless of leasing or buying won't have any bearing on warranty work for the most part. Any dealership doesn't give a shyt what you use as long as it's 5w-30 or whatever. They care about mileage, breaks, tires, and cosmetics. If you're paranoid, write down the damn mileage change logs in the maintenance book and hot glue the damn receipts to the back of it.

If anyone is dumb enough to change the oil, forgot to screw the drain bolt back on, drive for 5k miles, wonder why the engine sounds funny, and then bitches at the dealership afterwards. Just...wow......

I use a stapler.

What makes you you think a 2-year oil change interval is ok when Nissan recommends 6 months minimum?

Tell you what OP ... wait two years and then send off a sample of your oil to Blackstone Labs for an oil analysis and see what they have to say about the matter

Nixin · 04-25-2016, 05:46 PM

DC, honestly the cheapest maintenance and insurance to keep your Z running well is an oil change. DO NOT wait 2 years for an oil change.
