How much does an oil change cost in the UK?

Oil change cost by engine type

Prices below include labour and parts (oil and filter) at a typical UK independent garage. Dealer prices are usually 20 to 40 percent higher.

Prices are approximate and vary by garage, oil brand, and local labour rates. Always ask for a written quote before work starts.

Oil change cost by city (typical independent garage)

Labour rates vary across the UK. London and the South East are consistently more expensive than the North, Scotland, and the Midlands.

Based on typical workshop rates for a standard petrol engine using fully synthetic oil. Diesel and larger engines will be towards the higher end of the range.

What is included in an oil change?

A standard oil and filter service at a UK garage covers the following:

Draining and disposal of old oil

The garage will drain the old engine oil completely and dispose of it responsibly. This is an essential step: old oil loses its viscosity and cleaning properties over time, and leaving it in the engine causes accelerated wear.

Replacement oil filter

The oil filter traps metal particles, soot, and contaminants. A new filter should always be fitted with every oil change. Reusing the old filter with fresh oil means contaminants from the old oil circulate straight back into the engine.

Fresh engine oil to the correct grade

The garage will fill the engine to the correct level using the oil grade specified for your vehicle. Common grades include 5W-30, 5W-40, and 0W-20. Using the wrong grade can reduce engine protection and, on some modern engines, affect performance or economy.

Fluid top-ups and visual checks

Most garages will also check and top up coolant, screenwash, and brake fluid levels as part of the visit, and carry out a brief visual inspection of accessible components. This is not a full service, but it does mean obvious issues such as a split hose or a low tyre are likely to be flagged.

What affects the price of an oil change?

Engine size and oil capacity

A small 1.0L petrol engine holds around 3.5 litres of oil. A 3.0L diesel may hold 6 to 8 litres. Because oil is priced per litre, larger engines cost noticeably more to fill. Performance cars with dry-sump systems or large diesel vans can hold even more.

Oil specification required

Many European manufacturers specify a proprietary oil standard that goes beyond the standard viscosity grade. VW Group, BMW, Mercedes, and Renault all have their own specifications. Oils meeting these standards cost more per litre than generic equivalents.

Filter accessibility

On some engines the oil filter is awkward to reach, adding a small amount of labour time. Cartridge-type filters (common on newer European cars) tend to be quicker to replace than screw-on canister filters.

Garage type and location

Independent garages are typically 20 to 40 percent cheaper than main dealers for an oil change on an out-of-warranty vehicle. Mobile mechanics are often at the lower end of the price range and come to your home or workplace.

Common questions about oil changes

How often should I change my engine oil?

For modern cars, the standard interval is every 10,000 to 15,000 miles or once a year, whichever comes first. Older vehicles and those used heavily in stop-start city driving may benefit from shorter intervals of 6,000 to 10,000 miles. Many newer cars have a variable service indicator that alerts you when an oil change is due based on driving conditions rather than a fixed mileage. Always follow the interval in your vehicle handbook. When in doubt, once a year is a safe minimum.

What happens if I do not change my engine oil?

Skipping oil changes is the single biggest cause of avoidable engine damage in UK vehicles. Oil degrades over time and loses its ability to lubricate and clean internal components. Old oil turns into sludge that coats engine passages, starves moving parts of lubrication, and causes metal-on-metal wear. In serious cases this leads to a seized engine, which costs £2,000 to £8,000 or more to repair or replace. A £60 oil change every 12 months is the cheapest engine insurance you can buy.

What oil grade does my car need?

The correct oil grade for your car is specified in the vehicle handbook, usually on a page titled engine oil or lubrication. Common grades for UK cars include 5W-30 (most modern petrol and diesel cars), 0W-20 (newer fuel-efficient engines), and 5W-40 (older or higher-mileage engines). Some manufacturers such as BMW, Volkswagen Group, and Mercedes have their own oil specifications that go beyond the standard grade, for example BMW Longlife-04. Using the wrong oil can cause increased wear and may void the manufacturer warranty on a newer car. If you are unsure, ask the garage before work starts.

Can I do an oil change myself?

Yes, an oil change is one of the more accessible DIY car jobs if you are comfortable working underneath a car. You will need a drain pan, the correct oil and filter for your vehicle, a filter removal tool, and a way to safely raise the car. The main risk for DIY oil changes is using the wrong oil grade or filter, not torquing the drain plug correctly, or over-filling the engine. Used oil must be disposed of at a recycling centre, not poured down the drain. If you are not confident, the professional cost is low enough that having a garage do it is rarely worth skipping.

Is an oil change the same as a car service?

No. An oil change covers only the engine oil and filter, plus basic fluid checks. A full car service covers a much longer list of checks: brakes, tyres, lights, air filter, spark plugs, fuel filter, belts, suspension, steering, and more. An oil change is a subset of what a service covers. Some garages offer an oil and filter service as a standalone product between full service intervals. If your car has passed its service interval, an oil change alone is not a substitute for a full service.

How long does an oil change take?

Most oil changes take between 30 and 60 minutes at an independent garage. The drain time for old oil accounts for much of this. If the garage is busy or your car has an inaccessible filter or sump plug, it may take slightly longer. Mobile mechanics can often complete the job at your home or workplace in a similar time, though they need a level surface and access to the underside of the car.

Does a full car service include an oil change?

Yes. An oil and filter change is always included in a full service or interim service. If you have had a full service recently, you may only need a standalone oil change at the halfway point in your service interval. Some manufacturers specify an annual oil change in addition to the main service schedule, particularly for vehicles that cover low annual mileage. Check your service schedule to avoid paying for a full service when an oil change is all that is needed.

What is the difference between synthetic and semi-synthetic oil?

Fully synthetic oil is engineered to a consistent molecular structure, offering better performance across a wide temperature range, improved fuel economy, and a longer service life. Semi-synthetic oil blends synthetic base oil with conventional mineral oil, offering better performance than mineral oil at a lower price than full synthetic. Most modern cars require fully synthetic oil. Older or high-mileage engines sometimes run better on semi-synthetic or mineral oil, as fully synthetic oil is thinner and can seep past worn seals. Always check the grade and specification in your handbook rather than choosing by price.
