Your First Car: Essential Maintenance You Can't Ignore
You have the keys in your hand. The car is yours. Now comes the part nobody explains to you at the dealership or driving school: how to maintain it so it keeps working.
It’s not that it’s difficult. It’s that there’s a lot of scattered information, filled with technical jargon, written for someone who already knows. If it’s your first car—new or secondhand—what you need is a clear list of what to watch for and why. That’s exactly what you have here.
There are five things you can’t overlook. The rest will come later.
Oil: The Most Basic Engine Element
Oil lubricates all the moving parts of the engine. Without it, friction destroys the metal. With oil in poor condition, the effect is similar.
Each manufacturer sets a different service interval. In most modern cars it’s between 10,000 and 20,000 km, or once a year, whichever comes first. Check your vehicle’s manual for your specific car’s information.
What happens if you don’t change it? The oil degrades, loses its properties, and stops protecting the engine as it should. Over time, it can cause premature wear and, in extreme cases, serious damage. It’s the cheapest maintenance and the one with the biggest consequences if neglected.
If you bought the car secondhand and don’t know when the last oil change was, take it to a workshop. Get it checked before you pass the first 1,000 or 2,000 km.
MOT: Mandatory and Date-Specific
The MOT (Ministry of Transport test) is mandatory in the UK. If you have a new car, the first MOT is due four years from the registration date. After that, every two years until the car is more than ten years old, at which point it becomes annual.
The process is straightforward: book an appointment at an MOT testing station, take your car in, and within an hour you’ll know if it passes or not. The cost ranges from £40 to £60 depending on your region.
Not passing the MOT within the deadline is a traffic offense. Additionally, if you have an accident with an expired MOT, it can have consequences with your insurance.
The deadline is shown on your MOT certificate and also on your vehicle registration document. Write it down and keep track of it.
Tires: Pressure and Wear
Tires are the only contact between the car and the road. Their condition directly affects braking, fuel consumption, and safety.
Two things you need to watch:
Pressure: The correct pressure is indicated on a sticker on the driver’s door frame or in the manual. It’s measured in bars or PSI. Incorrect pressure—even if just slightly—increases fuel consumption, causes uneven tire wear, and can compromise the car’s stability during braking. Check it approximately once a month, always with cold tires.
Wear: Tires have wear indicators in the tread pattern. In the European Union, the legal limit is 1.6 mm of depth, although it’s recommended to check for replacement before reaching that limit. If you see the tread is almost flat, it’s time to consult the workshop.
Brakes: The Noise You Shouldn’t Ignore
Brakes don’t fail suddenly. They give warnings. Squeaking when braking is one of those signals. So are vibrations in the pedal or the feeling that the car is taking longer to stop than normal.
If you hear constant squeaking when braking, take the car to the workshop. Don’t let it go for weeks. The brake system has components that wear progressively—brake pads, discs—and catching it early is much cheaper than waiting for the problem to get worse.
How often do they need changing? It depends a lot on your driving style and mileage. There’s no universal fixed interval. The mechanic can see the condition of the pads and discs at each service and tell you how much useful life they have left.
Battery: Warning Signs Before It Stops Working
The battery is one of those components that works fine until one day it doesn’t. Pre-warning signs exist, but they’re easy to ignore if you don’t know them.
Pay attention if the engine starts with more difficulty than usual, if the headlights flicker, if warnings appear on the dashboard for no apparent reason, or if the battery needs charging more frequently than normal. These are signs that it might be starting to fail.
The average lifespan of a battery is between 3 and 5 years, though it varies depending on use and weather conditions. If the car is secondhand and you don’t know when the battery was last replaced, it’s worth having a workshop check it.
Start Building Your Service History From Day One
If you bought the car new, you have the advantage of knowing exactly the starting point. If you bought it secondhand with no documented history, that’s fine: just start now.
Every time you change the oil, check the tires, pass the MOT, or replace any part, write it down. The date, the mileage, what was done, and what it cost. You don’t need anything fancy to start.
Over time, that record is valuable: it saves you from “I don’t know when the last change was due,” it helps you plan future maintenance, and when it’s time to sell the car, a documented history speaks well of the owner who took care of it.
OwnAutoCare is a free app for iPhone, iPad, Mac, and Android that lets you keep that record from day one. You can note each service with its date and mileage, attach the workshop receipt, and set a reminder with the date for the next change. Your data is saved in your Google Drive or iCloud, with no intermediate servers.
Your car’s first maintenance always comes sooner than you think. What matters is that when it arrives, you already have the habit.
