ND oil change interval according to the car

  1. My model of MX-5 is: __MY23 ND 2L
  2. I’m based near: __High Wycombe
  3. I’m looking for technical help or recommendations on: __service interval

So the car indicates an oil change will be required somewhat within the 12K miles/1yr ‘standard’ for the car in the UK. Is this dynamic/based on how it’s driven on these vehicles? Interesting that I don’t thrash the car nor drive short journeys most of the time, but whatever. Just wondering if the car’s oil change recommendation is something folk use. Planning a 1500m road trip which will tip it over the edge, so prob need to get the service done early.

Also, whilst the car’s still under warranty, will use a Mazda dealer so there’s less argument over potential warranty claims, of which I have a minor one (door card a bit loose /clicking when you open/close driver’s door). Any recommendations for a firm at a reasonable distance from High Wycombe? There’s one in the magazine offering 10% discount to club members and they’re in Milton Keynes. Can’t recall their name - anyone know if they’re to be recommended?

I have used Japex in Kings Langley for my last 2 services on my ND2 2.0L 2020.
Great guys who know the cars well.

Sadly not a Mazda main dealer. But good to know when the car gets out of warranty.

It’s Brayley’s in Milton Keynes. I use the, on a regular basis and have no trouble with them. Ask for Ed Ward to do the work if you can, he’s a long standing Mazda tech there.

So anyone know about the oil change indication in the car’s display?

Hit the applications button on the display, then the vehicle status monitor menu. That’ll bring up the oil change monitor/miles etc. You can adjust it reset yourself in the display

Many cars have these displays these days, they are usually just mileage / time based reminders, personally if I had any car, in warranty or not, I would not hesitate to get the oil change done early in anticipation of a long trip because dirty old oil is one of a number of factors than can cause excessive wear in engines.

Yes I know. Question is if it’s reset at the last oil change is it normal for it to indicate the next change based on driving conditions etc, say at about 9K miles?

I will get the oil changed if this indication is reliable.

I’m not sure if that’s the case with the ND or it’s just a case of resetting to your or the Mazda dealer/service centre preferred (set) intervals.

As you know UK cars are set at the factory to 12,500 miles/12 months which ever the car reaches first.

From memory there is the option to use ‘variable’ service reminders in the settings but you would have to look for it.

From your description of the reminder it looks like your car may have been set up that way. If you definitely know when and at what milage the car was last serviced it would help. If you know the garage name you could ring and ask them what they did.

I have just looked at the latest Mazda MX5 manual Manuals & Know your Mazda | Mazda UK and in there it states that UK is Table 1 and indicates that later cars have the maintenance monitoring system. This indicates that they can, dependant on use, show the service required sooner than 12,500miles/12 months.

This is the first time I have seen this UK service schedule and tends to confirm that your cars oil is being monitored and it thinks it is not in good enough condition to go to 12,500 miles.

It depends if the oil change interval is displayed as a percentage or mileage. If it’s a percentage, then it’s “flexible” based on driving. This is how it should be set at delivery, with the “Scheduled” set to off. If it’s displayed as a mileage, then it’s a fixed interval. Even on flexible, it will never exceed 12 months or 12500 miles.

Interesting. It shows as miles, but indicates a mileage less than 12500 from the last service.

Last serviced at 1,452 miles in the Mazda service record

13,952 Miles Latest Scheduled Service Due Mileage in the Mazda service record, so 12500 from the last service as expected.

Current mileage is 6477

Current indicated mileage remaining before next oil change on the car’s display is 1869

Current indicated scheduled maintenance is in 7410 miles on the car’s display.

So it looks like it it wants an oil change by 8364 miles, about 5600 miles short of the mileage for a scheduled change. Of course I’ll do if that makes sense, just odd as I almost never redline it, let it warm up before pushing it, occasionally get it to 5 or 6k revs, rarely do trips less that 10 or 15 miles, etc etc.

As it’s displayed in miles it’s a fix interval. It could have been that it wasn’t set right when it was serviced last. If you want it changing to “flexible” your dealer can do that when they service it.

So you would ignore the mileage to oil change indicator in this case, unless I wanted an “unscheduled” oil change?

Have you looked at the latest manual that I linked to which I think is for the latest incarnation of the ND. See page 9-7 onwards It clearly shows that UK is now on schedule 1 which has no time or milage, it just shows 1st, 2nd, 3rd etc. It looks like things have changed but I could be wrong.

Yes, that’s classed as Flexible Servicing or “My Mazda” service. It been like that for ages. I think on the Mazda Connect screen on the NE is listed as Automatic.

Yeah at the top of table 1 it says

My Mazda Service is the maintenance monitoring feature that alerts you of maintenance
needs by turning on the wrench indicator light and/or displaying a specific message in the
instrument panel.
In any case, every maintenance must be done within 20,000 km or 12 months at the latest
after the previous maintenance, whichever of the three events (20,000 km, 12 months or dis‐
play/wrench indication) occurs first.

So I expect the wrench to come on when the oil service mileage expires before 12500 miles…

That is my interpretation.
With the latest cars you can NOT go beyond the ‘old’ limits but you can be called in early for oil.

Would be nice to get a sense of the actual algorithm that’s used to determine next oil service, but I guess we’ll never know.
