Car maintenance schedule by mileage: when to service your car

Your car maintenance schedule by mileage is set by the manufacturer's manual, and the rule is always the same: a job is due when you reach the distance or the time shown, whichever comes first. As a general guide, the RACE (Spain's largest motoring club) puts the oil change at every year or 15,000 km, brake fluid every 2 years and the timing belt usually at 150,000 km or 10 years. Below you will find the full table and a simple way to never miss one.

How often should a car be serviced in Spain?

It depends on the manufacturer. According to the RACE, scheduled services usually come every 10,000, 15,000 or 30,000 km, and each brand sets the exact plan for each model and engine. Cars in Spain show kilometres, so every interval in this guide is in km (15,000 km is roughly 9,300 miles).

Your first source is always the service book (libro de mantenimiento) or owner's manual. If you bought the car second hand in Spain and it came without one, the brand's official dealer can usually tell you the exact plan from the chassis number (VIN, número de bastidor).

There is one detail many drivers miss: almost every interval has two conditions, one for distance and one for time. If you drive little, time is what counts. Oil degrades, brake fluid absorbs moisture and the rubber of the timing belt ages even when the car sits parked. A car that covers 6,000 km a year cannot wait two and a half years for an oil change just because it "hasn't reached 15,000 yet". This catches out a lot of people who split the year between Spain and another country and leave the car parked for months.

Car maintenance schedule by mileage: the table

This is a reference table based on figures from the RACE and the DGT (Dirección General de Tráfico, Spain's traffic authority). Where there is no reliable general figure, we say so: in those cases the manufacturer decides.

Oil and filter: the job people forget most

It is the most frequent job and, for that very reason, the one that slips through most often. The RACE recommends changing the oil every year or every 15,000 km. If your car uses long life oil (the manual will say), the interval rises to 2 years or 30,000 km. In cars more than 15 years old it is worth shortening it: every year or before reaching 10,000 km.

The oil filter is always changed with the oil. Putting fresh oil in with the old filter is like taking a shower and putting your dirty clothes back on.

Brake fluid and brake pads: two different rhythms

Brake fluid has a time interval, not a distance one: every 2 years, according to the RACE. Over time it absorbs moisture and brakes less well, even if the car has hardly moved.

Brake pads, on the other hand, have no fixed interval. They depend on how you drive, whether you do town or motorway driving and how heavy the car is. What you need to watch is wear (the garage checks it at every service) and the warning signs: a metallic squeal when braking, the pad wear light on the dashboard or a pedal that feels different. If you hear noises, do not wait for the next service.

What happens if you don't change the timing belt in time?

The timing belt keeps the crankshaft and the valves moving in sync. The RACE usually places it at every 150,000 km or 10 years, although here more than anywhere the manual decides: some engines have shorter intervals and others use a chain instead of a belt.

If it snaps with the engine running, the car stops on the spot. In many engines the pistons and valves also hit each other, and what was a planned maintenance job turns into serious engine damage. It is one of the few repairs where waiting a bit longer saves nothing: the planned change costs far less than the breakdown it prevents.

The same applies the other way round: if you are selling, keep that invoice like gold. Our guide to why a full service history helps you sell your car explains why.

Tyres and battery: what you can check without a garage

Tyres are the only thing connecting your car to the road. The DGT sets the legal minimum tread depth at 1.6 mm, but recommends not going below about 3 mm, because under that braking on wet roads gets much worse. Driving on a tyre below the legal minimum is fined in Spain, according to the motoring press, with a usual fine of €200.

Check the pressure once a month, always with the tyres cold (before driving any distance). The correct figures are usually on a sticker on the driver's door frame or inside the fuel filler flap.

According to the RACE, a battery lasts 3 to 5 years. From the fifth year it can fail at any moment, and in very cold weather it loses up to 20% of its capacity. If yours is a few years old, have it tested before winter.

The 5-minute monthly checklist

You do not need to know anything about mechanics. Once a month, with the car parked and cold:

1. Tyre pressure, including the spare wheel if you carry one.
2. Fluid levels: oil (with the dipstick), coolant and screenwash.
3. Lights: dipped beam, main beam, indicators, brake lights and reversing lights. Ask someone to help or use the reflection on a wall.
4. Wiper blades: if they streak or squeak, it is time to replace them.
5. Tyre tread: look for the wear indicators in the grooves and check that the tread is wearing evenly across the tyre.

Scheduled service, ITV and real maintenance: not the same thing

They are often confused, and it helps to keep them apart:

• The scheduled service is the one the manufacturer sets in the service book. While the warranty lasts, doing it on time and getting it stamped is what protects you if something breaks.
• The ITV (Inspección Técnica de Vehículos) is Spain's compulsory roadworthiness test, the equivalent of the British MOT. It checks safety and emissions, so it confirms the car can be driven, not that it is well maintained. A car can pass the ITV with its oil change overdue. If you are unsure about the dates, see when your ITV inspection is due in Spain.
• Real maintenance is everything else: what you do between services, such as tyres, the battery, wiper blades or that squealing brake pad. It is often done at different garages and never recorded in any book.

The problem is that real maintenance is exactly what gets forgotten. Nobody sends you a letter to say your timing belt is turning ten.

How to never forget your car maintenance

The method that works is dull and simple: every time you do something, write down the date, the kilometres and what was done. With those three facts you can work out when the next job is due, by distance or by time. A notebook in the glovebox works. So does a spreadsheet. The hard part is not writing it down, it is remembering to write it down and then remembering to look.

That is where Vehistrack fits in. You message Jack, our assistant, on WhatsApp: "changed the oil and filter, 87,400 km", and he records it in the car's history with the date. You can also send him a photo of the invoice. When the next service, the ITV or your insurance renewal gets close, he warns you in good time. No app to install.

If you also fit a GPS tracker in your car, you do not even have to note the kilometres: the car tracker plugs into the OBD port under the steering wheel and reads the real mileage automatically. That way your mileage-based maintenance reminders arrive when the job is actually due, even if you never look at the odometer. We go into more detail in whether a car GPS tracker is worth it. If you just want the history and the reminders, there is more information on our page for individuals.

Frequently asked questions

What does "whichever comes first" mean in car maintenance?

It means the interval has two limits, one for distance and one for time, and the job is due as soon as the first one is reached. If the oil is due every year or 15,000 km and you drive 8,000 km a year, you change it every year.

Can I service my car outside the main dealer without losing the warranty?

In general yes, as long as the work follows the manufacturer's requirements, uses suitable parts and is stamped in the service book or backed by a detailed invoice. Always keep the invoices.

How often should the air filter and cabin filter be changed?

There is no reliable general figure: it depends on the manufacturer and on how you use the car. Check your manual. If you drive in very dusty areas, the air filter may need changing sooner.

If my car has a timing chain, can I forget about it?

A timing chain usually lasts much longer than a belt and in many engines has no replacement interval, but it is not eternal. If you hear a metallic rattle when starting from cold, mention it to your garage.

Is there a fine for not maintaining your car in Spain?

Not for skipping a service. But a tyre below 1.6 mm is fined, and a badly maintained car may fail the ITV.
