This 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. The reset procedure is different on the 2019 Focus (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 – though completely undocumented by Ford. All you do is:
- Turn on the ignition (or push the start button with the clutch up)
- 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 onwards.
Does this work on other Ford models?
You’ll have to try it and see. Logic would dictate that Ford has implemented the same procedure on all its current (pre-2019) models. 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 the model here.
I am told it also works on the Ford Fiesta.
Does it work on the latest (2019) 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!
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). 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.
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.
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.
Disclaimer: I take no responsibility if an oil change really is due and you ignore it.
