What car maintenance involves

Car maintenance is about preventing problems before they become expensive or unsafe. Regular checks and servicing help keep your vehicle running smoothly and protect its long-term value.

Routine maintenance typically includes:

  • Servicing and oil changes

  • Tyres, brakes, and suspension checks

  • MOT preparation and repairs

  • Fluid levels and warning lights

  • Wear-and-tear items

Staying on top of these areas can reduce breakdowns and make your car easier to sell later.

If you’re thinking about selling, our car selling guidance explains how maintenance impacts value.

Routine maintenance checks every owner should know

Servicing schedules

Following the manufacturer’s service schedule helps prevent mechanical issues and reassures future buyers.

Regular upkeep plays a big role in valuation — our car valuation guidance explains what buyers look for.

Tyres, brakes, and safety items

Tyres and brakes are critical for safety and are often checked during valuations and inspections.

Warning lights and dashboard alerts

Ignoring warning lights can lead to larger problems and reduced resale value.

MOTs, repairs, and roadworthiness

An MOT is a legal requirement and a key indicator of a car’s condition. Preparing properly can reduce failures and unexpected repair costs.

Common MOT-related issues include:

  • Worn tyres or brakes

  • Suspension wear

  • Lighting faults

  • Emissions problems

If repairs outweigh the car’s value, our scrapping guidance explains your options.

MOT guidance and preparation

If your car fails its MOT, you still have options depending on the cost and severity of repairs.

How maintenance affects your car’s value

Good maintenance doesn’t just improve reliability — it directly affects how buyers and dealers value your car.

Well-maintained cars tend to:

  • Attract higher offers

  • Sell faster

  • Raise fewer inspection concerns

Poor maintenance can reduce value, even if the car still runs.

Maintenance myths & misconceptions

“Servicing isn’t necessary if the car runs fine.”
Many problems develop quietly and only appear once damage is done.

“Old cars aren’t worth maintaining.”
Basic maintenance can keep older cars reliable and preserve resale or scrap value.

“Minor faults don’t affect value.”
Small issues can signal neglect and lower buyer confidence.

“I should fix everything before selling.”
Some repairs help value, others don’t — it’s about choosing wisely.

More information

Most cars need a service every 12 months or 10,000 miles, whichever comes first.
If you drive shorter trips, tow heavy loads, or use your car in extreme temperatures, servicing may be needed more often. Regular servicing helps prevent breakdowns and keeps repair costs low.

How to check if I need a new car battery?

You should never ignore the following dashboard lights:

  • Engine management light (amber or red)

  • Oil pressure warning

  • Battery/charging warning

  • Brake system warning

If a red light appears, stop the car as soon as it’s safe and investigate immediately. Ignoring these can cause expensive engine or electrical damage.

You may need new tyres if:

  • Tread depth is below 1.6mm (the legal limit)

  • There are cracks, bulges, or uneven wear

  • The steering wheel vibrates at speed

  • Braking distances feel longer

Checking your tyres regularly improves safety and fuel efficiency.

What fluids should I check regularly?

Every driver should check:

  • Engine oil

  • Coolant/antifreeze

  • Brake fluid

  • Power steering fluid

  • Windscreen washer fluid

Running low on any of these can cause performance issues, overheating, or even engine failure.
