Yes, never miss a manufacturer’s sceduled oil service (miles or time), but the question here is the benefit of changing the oil more frequently than they deem ‘necessary’.
Re golden vs black oil, you actually want the oil to go black quicker, not slower. Good quality oil goes black quicker because it’s doing a good job of suspending all the (black) cr@p in the oil rather than leaving the cr@p to stick itself to engine parts 
I always pre-fill the oil filter and do it several times until its at the top of the filter.
Very simple answer, that “Oil Change” alert is set by owner iirc, it’s nothing to do with any sensors and you can reset it yourself in the menu. I’m guessing it wasn’t reset after the oil change, so it’s still counting down from the previous one.
Just stick with the scheduled 12,000 miles or 12 months servicing (including an oil change) and the car will be fine, ran my previous ND1 like that for over 7 years and the engine was still healthy.
The NC will turn over but not fire if you depress the accelerator pedal to the floor. I often do this if it has stood for a couple of weeks just in case…
Yes, flexible servicing needs to be turned on by the dealer. You’ll notice the the services are headed 1st, 2nd, 3rd etc rather than by time or mileage.
I see no mention of Diff oil on that page, whereas it is included in my NC owner’s manuals immediately after transmission for every fourth service.
However none mention clutch fluid, and I’ve had to argue with both main dealers it was part of the brake fluid change.
RE: Diff oil; you don’t want to know the answer to that question 
If they have it in the air it hardly going to cost them time. I bleed the brakes recently and missed out the clutch as it was tricky to get at on the usual supports. Need to try harder….
So you still have old fluid in the system… 
I really hope you don’t pay for a full service every year after 1500 miles, that’s literally just throwing your money away.
Modern oils and fluids last for many thousands of miles. I’d stop using your regular garage as they’re almost robbing you, unless you do it yourself, although that’s still a complete waste of money.
Keep on topic please.
Interesting discussion about oil changes.
My ND only does about 1.5k miles year, but as It’s still under warranty the annual service is not something I want to vary just yet.
But how times have changed! My first car was a Ford Popular with white metal bearings and an oil pressure of about 10 psi (a bit worn). Recommended oil change was every 500 miles with SAE 30 oil. No multigrades then!
I fitted an external cartridge filter and got it up to 1000 miles!
Maybe, but I don’t mind spending money on it. It’s not like I’m throwing it away on booze or cigarettes. It isn’t always a ‘full service’ (full as in brake fluid and extras) after 1-1.5K miles anyway.
And ask 5 people about changing oil after 1-1.5K miles and a YEAR on, and you often get 11 different opinions. Indeed, ask 6 people about changing brake fluid after 2 years, but only 2-3K miles on, and you’ll often get 15 different opinions.
Which says to me know one really knows for sure. Hence I just stick to the manufacturer’s schedule.
So the car is clearly set up today for mileage based intervals. And I can manually adjust that mileage.
What’s odd is that when I reset it (before I manually change it) it defaults to 6250 miles, exactly half the default in the manual…
I think that’s because under certain conditions (see your Owner’s Manual) the oil should be changed at 6250 miles so it defaults to the worst case scenario.
6250 miles is the tyre rotation, did you reset that too?
Tyre rotation is switched off. This is def oil default.
Fair enough. I realise it’s a very subjective issue, but I’ve never understood the 12,000 miles or 12 months specification. That’s like car manufacturers suggesting that oil will stop protecting your engine after 12 months, regardless of mileage - will it? I honestly don’t think so.
I’m sure if you asked the actual people who manufacture the oils, then you’d get a totally different answer.
The bottom line is, it’s all about money. Car manufacturers want to sell you their oil, hence 12 months. Independent garages want you to change your oil, hence the 12 months, and oil manufacturers want you to buy their oil, hence the 12 months.
I’m absolutely positive that if you spoke to a scientist who knew all about the actual production of oils, they’d tell you that car engine oil will continue to protect your oil long after 12 months.
Same thing with brake fluid. Just how much water/moisture does it actual absorb? I’ve owned cars in the past, Audis and BMW’s and I never once changed the brake fluid - pads and discs yes, fluid no. When I changed the brake fluid on my '94 NA Eunos Roadster, many years ago, did I notice/feel the difference, no, not one bit.
As I said, all subjective, but to change oil after anything less than 10-12,000 miles is a genuine waste of money, and probably not allowing oil to do its job of actually cleaning your engine - as someone said earlier, black oil is what you want to see, as it’s done its job, then change it.
I would be changing my oil once a decade then. Think I’ll keep doing it every year instead 
It is subjective to a certain degree, I agree. But then I’m in the camp that buying 20 fags and 4 cans is a genuine waste of money,
