Ford Focus service cost
Full service at an independent garage, parts and labour included — the annual benchmark for every Focus engine.
- Interim £95 – £130
- Major £235 – £320
- Add an MOT for £35 – £45
A Ford Focus full service costs £150–£205 at an independent garage, an interim £95–£130 and a major £235–£320. The complication is peculiar to this car: across its generations the Focus has taken three entirely different Ford oil specifications, and the badge on the boot tells you which one you need — nothing. Getting that single line right is worth more than shopping the price.
Focus service cost by engine — and which of the three oils it takes
Same checklist across the range; the money moves with the sump. Note how the specification column refuses to line up neatly with either fuel or age — that is the whole problem with this model, and the reason the section below exists.
| Engine | Oil specification | Full service, fitted | Watch for |
|---|---|---|---|
| 1.4 / 1.6 Duratec petrol | WSS-M2C913-D · 5W-30 | £150–£180 | The cheapest Focus to service, no surprises |
| 1.0 EcoBoost | WSS-M2C948-B · 5W-20 | £165–£205 | Belt runs in this oil — spec is not optional |
| 1.5 EcoBoost | WSS-M2C948-B · 5W-20 | £165–£205 | Four plugs at major level, not three |
| 1.6 TDCi diesel | WSS-M2C913-D · 5W-30 | £160–£195 | Fuel filter joins the major |
| 1.5 / 2.0 EcoBlue diesel | WSS-M2C950-A · 0W-30 | £170–£205 | Third spec — thinner, low-SAPS, for the DPF |
Independent prices to Ford’s schedule, parts and labour included; all ranges sit inside the national Focus row on our car service cost guide. Performance ST and RS variants take more oil and more plugs and sit at the top of the range — confirm the specification on the filler cap rather than assuming. A main dealer charges roughly 50% more for the identical work.
One nameplate, three oil specifications — the Focus problem
No other car in our range asks this much of a parts counter. A Focus can want WSS-M2C913-D in 5W-30 if it is an older Duratec petrol or a TDCi diesel; WSS-M2C948-B in 5W-20 if it is a three-cylinder EcoBoost; or WSS-M2C950-A in 0W-30 if it is one of the later EcoBlue diesels. Three codes, three viscosities, one badge. Buy oil by looking at the car and you have roughly a one-in-three chance of being right, which is precisely how the wrong oil ends up in the right engine.
Each wrong answer fails differently, and that matters. Put 5W-30 into an EcoBoost and you are not merely running thick oil — you are running the wrong chemistry past a timing belt that lives submerged in it, which is the failure our wet-belt page exists to price. Put a non-low-SAPS oil into an EcoBlue diesel and the ash it leaves builds in the particulate filter, where no amount of motorway driving will burn it out; that bill is on our DPF guide. Neither mistake announces itself for a year or two, which is why nobody ever connects the cheap service to the expensive consequence.
So the question worth asking when you book, and worth checking on the invoice before you pay: which of Ford’s three specifications does my engine take, and will that code be printed on the invoice? The code lives on the oil filler cap and in the handbook, and any competent garage reads it off the system without hesitating. It is also what protects the warranty — the block exemption rules explained on our service cost hub require the correct specification to be used and recorded, so an invoice naming a brand instead of a standard is doing half a job.
The cheap suspect here is not a part but a habit: buying oil on price at a motor factor and handing it to the garage. Supplying your own oil saves perhaps fifteen pounds and transfers the entire specification risk from a professional to you. On a Focus, of all cars, that is a bad trade.
How often a Focus needs servicing
The Focus kept a fixed schedule where its smaller sibling did not. Ford’s interval for the Mk3 generation, EcoBoost included, is twelve months or 12,500 miles, whichever comes first — a plain count with no oil-life monitor making judgement calls. That is worth knowing if you own both a Focus and a newer Fiesta, because the Fiesta’s own schedule stretches considerably further and the two cars in one driveway do not follow the same rules; the detail sits on the Fiesta service page.
The items that age by time rather than distance are where a low-mileage Focus catches people out. Brake fluid runs on a roughly two-year cycle whatever the odometer says, because it absorbs moisture from the air rather than from driving. Coolant and the cabin filter behave the same way. A Focus covering 5,000 miles a year can be years from its next oil change on paper and still overdue on three other counts, which is the honest argument for the annual full service rather than waiting for a mileage trigger.
Spark plugs and the fuel filter are major-service territory. On the petrols the plugs come round at the two-yearly major; on the TDCi and EcoBlue diesels the fuel filter joins them, and skipping it is a false economy that ends at the injectors. That is also the visit where a garage will find the things the schedule cannot predict, so budget the service and keep headroom for the phone call.
One thing the MOT will not tell you: it tests condition on the day and says nothing about whether the service is overdue or whether the oil in the engine is the right standard. A Focus can pass cleanly with an EcoBlue quietly ashing up its filter. The MOT guide covers the test; this page covers the schedule the test ignores.
Why the paperwork is worth more on a Focus than on most cars
The Focus is one of the most heavily traded used cars in Britain, which cuts both ways. There is always another one for sale, so a buyer facing a thin service record simply walks to the next advert rather than negotiating — the discount you accept is not a haggle, it is the whole difference between selling and not selling. Most modern examples carry a digital service record held by Ford rather than a stamped book, and a good independent can update it; ask them to, because an unstamped digital record and a genuinely missed service look identical to whoever checks it next.
Worth keeping specifically on this model: invoices that name the oil specification code. For an EcoBoost or EcoBlue owner, that paperwork is the evidence that the engine was fed correctly through your ownership — and on cars where oil specification is tied to a known weak point, evidence is what turns an awkward conversation into a short one. It costs nothing to ask for, and it is the cheapest thing on this page.
| Engine oil, 4.1 litres to WSS-M2C948-B spec | £45 |
| Oil filter and sump plug washer | £12 |
| Air filter | £16 |
| Labour, 1.75 hours at £58/hour | £102 |
| Total, 70-point check included | £175 |
The same visit at a Ford dealer prices around £250–£310. A 1.6 TDCi at major level lands nearer £270 once the fuel filter and plugs are counted. Booked alongside an MOT, add £35–£45 rather than the full capped fee.
FAQ
How much does a Ford Focus service cost?
£150–£205 for a full service at an independent garage, £95–£130 for an interim and £235–£320 for a major. A main dealer charges roughly 50% more for the same checklist. EcoBoost and EcoBlue models sit at the top of the range because of the specialist oils they require.
What oil does a Ford Focus take?
One of three Ford specifications depending on engine: WSS-M2C913-D in 5W-30 for older Duratec petrols and TDCi diesels, WSS-M2C948-B in 5W-20 for the EcoBoost petrols, and WSS-M2C950-A in 0W-30 for the later EcoBlue diesels. The code is on the filler cap and in the handbook.
How often should a Ford Focus be serviced?
Every twelve months or 12,500 miles, whichever comes first, on the Mk3 generation including the EcoBoost engines. Unlike the newer Fiesta, the Focus uses a fixed count rather than an oil-life monitor. Brake fluid, coolant and the cabin filter age by time regardless of mileage.
Can I put 5W-30 in a Focus EcoBoost?
No. The three-cylinder EcoBoost needs WSS-M2C948-B in 5W-20, because its timing belt runs submerged in the oil and the wrong additive package degrades the belt. Ford allows a small top-up with an ACEA A5/B5 5W-20 if the correct oil is unavailable, but that is a stopgap, not a substitute.
Is a diesel Focus more expensive to service?
Modestly — £160–£205 for a full service against £150–£180 for an older petrol, driven by the oil specification and the fuel filter at major level. The larger cost is indirect: short urban journeys stop the particulate filter regenerating, and that repair dwarfs any servicing difference.
What is included in a Focus major service?
Everything in a full service plus the two-yearly items: spark plugs on petrols, fuel filter on diesels, brake fluid, and coolant if due. It typically lands every second visit, and on a diesel it is the one to book properly rather than trimming, because the fuel filter protects the injectors.
Will servicing my Focus outside a Ford dealer void the warranty?
No. Block exemption rules protect you provided the garage follows Ford’s schedule, uses original-equipment quality parts and the correct oil specification, and records the work. Ask for the specification code on the invoice and for the digital service record to be updated before you pay.
How long does a Focus service take?
Around two hours of workshop time for a full service, though most garages will keep the car for a morning. An interim is closer to an hour. A major can take half a day when plugs, brake fluid and a diesel fuel filter all fall due together.
