How much does an oil change cost?

An oil change is the cheapest job on a car that can save you the most money, and it is the one people put off longest, because nothing looks wrong when it is overdue. Oil does not run out. It wears out quietly, and the engine keeps running on it right up until something expensive happens.

This guide gives the real UK prices first, then the part that actually decides whether you are getting value, which is whether an oil change bought on its own is the right thing to buy at all.

What you are paying for

A proper oil change is not just fresh oil. The job is to drain the old oil while the engine is warm, replace the oil filter, fit a new sump plug washer, refill with the exact grade and quantity the manufacturer specifies, run the engine and check for leaks, reset the service indicator, and take the old oil away for recycling.

Two things move the price. The first is how much oil the car takes: the handbook gives an exact figure, and most family cars sit somewhere between four and six litres while larger engines take considerably more. The second is which oil it has to be, and that is set by the manufacturer, not by the garage. A long life synthetic to a specific manufacturer approval can cost several times what a general purpose oil costs per litre, which is most of the difference between a £90 bill and a £250 one.

If you are not sure whether yours is due, our guide to checking your engine oil covers reading the dipstick properly, what healthy oil looks like against oil that is finished, and the two minute check that tells you whether you need a garage this week or this month.

What an oil change costs in the UK

The clearest public price data comes from the RAC, which publishes what its own mobile mechanics charged by manufacturer. For October to December 2025 the average oil change came to £229, covering draining the old oil, a new oil filter and a refill.

Here is how that average breaks down by manufacturer.

Read those figures for what they are. They are prices for a mechanic who drives to your house with the oil, the filter and the means to take the waste away, so they carry the cost of the van and the travelling. A local independent garage doing the same work on a ramp is usually cheaper, and a main dealer using its own branded oil is usually dearer. Our comparison of a mobile mechanic against a garage sets out where each genuinely wins, and main dealer against independent covers the price gap on the same job.

The spread between makes is not the garage being greedy either. It tracks oil quantity and specification. A car that takes eight litres of an oil built to one manufacturer approval will always cost more to change than a small petrol that takes four litres of a common grade.

Why an interim service is often the better buy

This is the part most price guides leave out, and it is worth more than the price list above.

An interim service is an oil and filter change, with a check of around 30 other items wrapped around it: brakes, tyres, lights, steering, suspension, exhaust, and every fluid level under the bonnet. The RAC puts an interim at roughly a third to a half of a full service, and a full service on a medium car at £210 to £300. That puts a typical interim somewhere around £70 to £150.

In other words, the checklist version of the same job frequently costs less than the £229 average for an oil change on its own. If you are ringing round for an oil change price, ask what an interim service costs at the same time, because the answer is often lower and always covers more. Our guide to interim against full service explains which one your mileage points to, and what is included in a full service lists what the extra money buys. For the wider picture on price, see what a car service costs.

There is one case where a standalone oil change is exactly right: a car that has just had a full service but is racking up motorway miles fast, or an older engine that a mechanic has recommended keeps fresh oil in it more often than the schedule requires.

How often does the oil actually need changing?

The general rule for a modern car is every 12,000 miles or 12 months, whichever comes first, and every 6,000 miles or six months where the manufacturer sets a shorter schedule or the car is on an interim and full service alternation.

The months matter as much as the miles, which surprises people who barely drive. Oil degrades by absorbing combustion by-products, water and unburnt fuel whether the car is moving or not, so a low mileage car still needs its annual change.

Long life or variable servicing complicates it. On these cars a computer estimates oil condition from how you drive and can stretch the interval to two years or up to 20,000 miles or so. That calculation assumes a reasonable share of long, hot runs. A car doing four mile school runs in winter never gets its oil hot enough to boil off the condensation and fuel that dilute it, so the honest answer for a short journey car is to change the oil on the shorter fixed interval in the handbook rather than waiting for the light. Our guide to how often you should service your car covers this in full.

The grade matters more than the price

"Fully synthetic" on the bottle is marketing, not a specification. What matters is the standard the oil is built to, and for anything with a catalytic converter or a particulate filter the relevant family is the ACEA C class, defined by the European Automobile Manufacturers Association as catalyst and filter compatible oils.

Two details in the current 2023 sequences are worth knowing, because a lot of what is written about oil online is out of date:

• C1 no longer exists. It was withdrawn with the 2021 sequences, so an oil still sold as meeting C1 is being described against a standard that has been retired.
• Only C4 is genuinely low ash. C2, C3, C5, C6 and C7 are all mid SAPS oils, meaning a reduced but not minimal level of the sulphated ash, phosphorus and sulphur that clog a filter and poison a catalyst. The categories also differ by viscosity, so C2 and C3 are not interchangeable even though both protect a filter.

The practical version: your handbook names the exact standard, often an ACEA category plus a manufacturer approval such as a VW or BMW number, and the garage should be putting in an oil that carries it. Ash that the filter cannot burn off simply accumulates, and once it does the fix is a clean or a replacement, so an oil saving of £20 can become the price of a DPF clean. Using the wrong oil also gives a manufacturer a reason to look hard at a warranty claim, which our guide to servicing and your warranty explains.

So ask one question when you book: which oil, to what specification, and does it meet what my handbook asks for. A good garage answers it in a sentence.

An oil leak is an MOT failure

Oil that is leaking rather than being burnt has a legal consequence most drivers do not expect. Under section 8.4.1 of the DVSA MOT inspection manual, fluid that is "leaking excessively and likely to harm the environment or to pose a safety risk to other road users" is a Major defect, which is a fail. Fluid "leaking continuously and likely to pose a serious risk to road safety" is Dangerous.

The manual gives testers something measurable rather than leaving it to opinion: a fail applies where the leak forms a pool on the floor more than 75mm across within five minutes, or where several smaller leaks together add up to the same rate. A tester can also refuse to carry out the test at all if a leak is excessive, which means a wasted trip and a second fee.

Worth knowing what is not caught by this: leaks of coolant, screen wash and the AdBlue used by selective catalytic reduction systems are not failure items. Engine oil is. If you have a patch on the drive, get it looked at before the test rather than after it, and read what is checked in an MOT and the most common reasons cars fail to see what else the tester will be looking at.

Oil disappearing with no puddle underneath is a different problem, and the exhaust usually tells you: blue smoke means the engine is burning it. Our guide to what exhaust smoke colour means works through where it is going, whether that is worn valve stem seals, piston rings or a failing turbo.

What happens if you leave it

Old oil thickens and turns to sludge, and sludge blocks the narrow galleries that feed oil to the top of the engine and to the turbo bearing. The parts that starve first are the expensive ones. A turbo spinning at over 100,000rpm on oil that is not reaching it fails quickly, and a badly sludged engine can lose a camshaft or the bearings.

The warning you get is the oil pressure light, a red oil can symbol, and it is not a reminder. It means stop as soon as it is safe and switch off, because pressure has already been lost. Our dashboard warning lights guide covers which lights mean stop now and which mean book it in. Overheating that follows starved lubrication can also take a head gasket with it, and a head gasket repair costs many times an oil change.

Doing it yourself, and the bit people get wrong

Changing your own oil is one of the more approachable jobs on a car, provided you can raise it safely on axle stands and you have the exact oil and filter for the engine. The parts cost a fraction of a garage bill.

The part that trips people up is the used oil. Never pour it down a drain, and never burn it. The Environment Agency is blunt about this, and the reason is practical rather than bureaucratic: oil in a watercourse strips oxygen out of the water and coats the feathers and gills of anything living in it. A litre goes a very long way. Take it to a household waste recycling centre, which will accept small quantities from the public, and take the old filter too.

Two things that catch out people who pay somebody else to do it on the cheap. A business carrying away waste oil must be a registered waste carrier, and you can check that for free on the Environment Agency public register. And paid repair or servicing work carried out on a public road is a criminal offence under section 4 of the Clean Neighbourhoods and Environment Act 2005, with a maximum fine of £2,500. If you have no off street parking, a mobile oil change at the kerb is not a legal option, whatever the advert says.

An oil change is not a service history

An oil change on its own does not fill in the service book, and that matters when you sell. A buyer wants a stamped record and a warranty provider wants evidence the schedule was followed, and neither is satisfied by a stack of receipts for oil. If you are keeping the car for a few more years, the interim service you were already going to be offered is what builds the record. Our guide to what a full service history is worth puts numbers on the difference at resale.

Getting a fair price where you are

Ask every garage the same five things and the quotes become comparable: which oil and to what specification, how many litres the car takes, whether a new oil filter and sump washer are included, whether the service light reset and the disposal of the old oil are in the price, and what the total is including VAT.

Then compare two or three local garages rather than accepting the first number. Prices for identical work vary more than most drivers expect, and our guides to the questions to ask before booking and the signs a garage is overcharging cover how to tell a fair quote from a padded one before you hand over the keys.
