Mobil 1 extended service oil

Trips

I usually change it at 5k even though you can go higher.

I don't put a lot of miles per year probably 5k so in my case its more of a yearly thing.

We'll put closer to 3000 km (well under 2000 miles) our summer-only vehicle here in our sometimes-seven-months-of-winter climate. That's why I'm interested in a perhaps 3-year oil-change interval rather than annual.

I do 5K or 6 mos. as that is what it takes for warranty.......my Ram truck I do yearly as I don't drive it , maybe 5K year. oil is cheap insurance.

You know, I wasn't sure what Nissan's official "regular service" interval was, so last night I checked the maintenance manual in the glove box and, sure enough, 8K km (5K miles), or 6 months, whichever comes first.

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.

good luck with the stealership.

oil doesn't 'go bad' but it's up to you how you want to store your car. I swap the oil before storage. after storage I drive a few hundred clicks then swap the oil.

I change my oil every 5k km. although I'm doing one at 3k before my road trip.

It's no longer a question of oils or storage. It's the question of what procedure the owner has to follow, and prove with receipts, in order to maintain Nissan's warranty. To me, this means dated receipts for filter and oil as proof that the oil was at least purchased on specific dates. Although these do not provide proof that the old oil and filter were replaced with new, they are strong evidence that it was. After all, what will one do with a collection of new jugs of oil and new filters other than use them?

I'm curious as to what those reasons are.

As has been mentioned before, for your circumstances, it's not usually dirt or oil degradation that is the problem, it's the acids and other crap that get in your oil. Need to flush that stuff out on a regular basis.

I just spelled them out.

What "acids and other crap" get into the new oil after draining the old oil, putting in the new oil and then not starting the vehicle for 6 or more months?

SouthArk370Z

You did a piss-poor job.

Unless you are cleaning/flushing the engine before putting in the new oil, it's the same crap that was there before you did the oil change. It will be less concentrated than before the change, but still there.

It also depends on how many miles you drive each time. It is a good idea to drive at least 20 miles or more and keep the oil temp around 210 to burn off any condensation in the oil. The worst scenario is to drive it for a few miles and shut it down. It would create more condensation each time.

I think you will be fine with M-1 oil & filter change every couple of years if you drive it enough to burn off the condensation in the oil.

im sure darwin will take care of his child ..
