Ford Focus oil change messageThis article was originally written a few years ago, but it has become extremely popular, and gets hundreds of hits a week.

The original article refers to all models between 2016 and 2018 (not the latest model). The reset procedure is different on the 2019 Focus, and be careful with that because there may be an issue with the latest model that Ford is being very cagey about (see later).

It all began back in 2016, when I got a message on my brand new Ford Focus TDCi Titanium centre display telling me that it was due for an oil change. I wouldn’t have minded, except that it was only on 5,500 miles and my official service points (set by my lease agent) are every 12,500 miles.

I spoke with the local dealer and they said just to book it in so they could reset it. I wasn’t too keen on that, since visits to the dealer inevitably mean at least half a day in lost lesson time.

I didn’t for a moment think it was anything other than an erroneous message. There is an oil warning lamp on the dash which I would never ignore, but centre display messages are a different matter entirely. I mean, how many of us have been driving up a 40% slope only to be advised to change the gear to 4th, 5th, or even 6th? The car just won’t do it. Before I quite realised this, my first action was to buy an OBD II monitor tool so I could check/reset the message myself, but the OBD found no faults, and there was nothing to reset. I should have realised this – and the oil change warning remained stubbornly visible.

Then I did what I should have done in the first place and Googled it. It turns out Ford has a system which gives an oil change warning at various points based on how it thinks the car is being driven. No fault is logged, since the trigger is software-based and is “calculated”. Apparently, you used to be able to set different trigger points manually (in America, at least), but there is no such option in the UK that I can see.

Since 2016, and across at least four other Focuses, I’ve had it come on at as low as around 1,000 miles, and at other silly points shortly after a service. None of my pupils (or me) drives it that badly, of that I’m certain.

How to reset the oil change warning

Resetting it is incredibly simple (pre-2018) – though completely undocumented by Ford. All you do is:

  1. Turn on the ignition (or push the start button with the clutch up)
  2. Press the brake and accelerator fully down

After a moment, the centre display will tell you that the reset is in progress. Keep the pedals down until it informs you that reset is complete. No more oil change warning! From what I understand, this applies to all Focus models from MkII up until the last of the pre-2018 models.

Does this work on other Ford cars?

You’ll have to try it and see. Logic would dictate that Ford has implemented the same procedure on all its current (pre-2019) vehicles. However, when you consider Ford’s indexing system at the back of the User Manual, logic isn’t something they seem to waste much time on, and there’s every possibility that the reset procedure is totally different on other models. If you try it and it works, drop me a line so I can add it here.

I am told it also works on the Ford Fiesta and C-Max.

Does it work on the latest (2018) Focus?

No. Resetting the oil on the new model is done through the settings page on the information console (this is how it ought to have been on the earlier models). You simply scroll to the little cog symbol, then select Information, then scroll down to Oil Life. Press and hold OK and it resets after a few seconds. Mine came on after 3,900 miles!

However, be aware that many people are experiencing the problem in the new (2018) Focus. The dealers are playing as ignorant as ever, and Ford as secretive as ever, but piecing information I have received from readers together there may be an issue with the 2018 Focus where the oil change warning ought not to be ignored.

How soon should I get my oil changed when the warning message comes on?

For a Focus, if your car is under the manufacturer’s warranty then I think they allow 1,000 miles on top of the normal service points (but check that with your local agents). My lease company allows me the range of 11,500-13,500 to book it in for a service. Whatever your local agent allows, outside of that might affect your warranty, so I say again: check with them before assuming anything.

Of course, if the oil change warning message appears before 12,500 miles (or whatever your service points are) then you can safely ignore it (or reset it, as explained above) in the pre-2018 models. It isn’t a sensor warning, just a software-based calculated value. If the oil warning dashboard light comes on, though, you mustn’t ignore that.

Note that the 2018 Focus may have an issue, so be careful if you ignore the warning.

You shouldn’t ignore the message because you could damage your car

Someone wrote to me making this point. As I have explained above, the alert (it isn’t a warning) is calculated based on how the in-car computer thinks you’re driving. Frankly, when it comes on at around 1,000 miles when you’ve only had the car a few weeks, or several days after it has had a service, and the oil definitely isn’t old, yes you can ignore it. Having said that, read the update at the end of this article relating to the 2018-onwards models (between the lines, there may be an issue that no one at Ford is revealing).

My lease agent sets the service points at every 12,500 miles. They will not allow me to have it serviced any earlier (±1,000 miles). I know that Ford talks of 7,500 mile service points, and that’s fine. If you have a private vehicle then follow their advice. But if the warning comes on at any other time before that you can safely reset it – if nothing else, until you can get it in for its service.

However, note that the 2018 Focus may have an issue, so be careful if you ignore the warning.

Update 10 April 2019: I have heard from an instructor who is with the AA that they’ve been told not to reset the message if it comes on with the 2018-onwards vehicles (the latest model), but to book it into the dealership. My own lease agent hasn’t said anything.

I must say that this would be extremely annoying, as my personal experience of my dealership is that even when there is indisputable video evidence of an intermittent fault occurring several times, they will still insist of having it in for a full day, then not find anything wrong (even though it was obvious they wouldn’t because of what “intermittent” means), and then want it back again the next time it happens. Every lost day costs me up to £200 in earnings.

They did it when I had the floppy clutch pedal problem last year. It turned out to be a known issue with one of the cylinders, and the engineer actually witnessed it sticking down, but they still wanted the bloody thing in, did a namby-pamby hydraulic fluid bleed, then had it in for another day when that didn’t work – which I discovered about an hour after taking it away the first time.

Right now, Sync3 has a habit of freezing (though as of April 2019 there is an update which fixes that). Judging from the Google results on that, it is another known issue. I have videoed the damned thing in its frozen and unresponsive state and shown it to them at the dealership. And… they want it in for a full day to test it. Aaargh.

Update 12 May 2019: Another reader tells me that their dealer has suggested there is a problem with the latest Focus engines and “the oil degrades”. Personally, I cannot see how the oil – synthetic motor oil – can degrade ten times faster than it should, but be aware of this if you have a 2018-onwards Focus.

Disclaimer: I take no responsibility if an oil change really is needed and you ignore it – especially in the new (2018-onwards) Focus, which may have an issue that Ford isn’t letting on about.
