What a car service actually improves (and how it can save you money)

It’s easy to see a car service as just another job on the to-do list. In reality, regular servicing plays a big part in how well your car runs, and how much it costs you in the long run. A proper car service isn’t just about ticking boxes! It’s about spotting wear early, keeping things working as they should, and avoiding problems that get expensive when they’re left too long.

While it isn’t a legal requirement like your MOT, we can’t recommend regular servicing enough. After all, who wouldn’t want to save money on maintenance and avoid bigger repair bills down the line?

What to expect in this piece:

• How servicing prevents expensive repairs
• How it saves you money on fuel
• How it protects your cars value

1. Prevents costly repairs

Most major repairs don’t happen suddenly. They develop over time from small, manageable issues.

During a service, key components such as fluids, brakes, tyres, and engine parts are checked for wear or faults. Picking up problems early, like low fluid levels, worn brake pads, or minor leaks, is far cheaper than dealing with a breakdown or mechanical failure later on.

Preventative maintenance reduces the risk of unexpected repairs and helps avoid emergency garage visits.

2. Improves fuel efficiency & reduces running costs

A well-serviced car runs more efficiently. Fresh engine oil, clean filters, and properly maintained components allow the engine to work as it should – without unnecessary strain. Dirty air filters restrict airflow, which means the engine works harder and consequently, more fuel is used.

Similarly, old oil in your car thickens and increases friction, which reduces efficiency. A recipe for disaster and more £££ spent.

When a car isn’t maintained, fuel consumption often increases and parts wear faster. Regular servicing helps maintain fuel efficiency, reduce emissions, and cut day-to-day running costs. Small savings at the pump can quickly add up over the year.

3. Protects your car’s value

A full service history is one of the first things buyers and dealerships look for. Regular servicing shows a car has been properly cared for, helping to maintain resale and part-exchange value while reducing the risk of MOT failures caused by neglected components.

• Skipping services can invalidate warranties, meaning repairs that should be covered may come out of your own pocket.
• Cars with a full service history can be worth 15 – 25% more than similar vehicles without one, while missing history often knocks thousands off resale value.
• Some finance agreements require servicing at recommended intervals, and failing to do so can cause issues when returning or settling the car.

Simply put, keeping up with servicing protects both your car and your wallet in the long run.

Interim vs full car service – What’s the difference?

Interim service (usually every 6 months or 6,000 miles): A lighter check, ideal for high-mileage drivers or between annual services
Full service (annually, or every 10,000 miles): A more comprehensive inspection covering key mechanical, safety, and fluid checks, such as:

• Engine oil & oil filter replacement
• Air filter inspection/replacement
• Brake pads, discs & brake fluid check
• Suspension components
• Tyre tread depth & pressure
• Battery health
• Lights & electrics
• Coolant & other fluid levels
• Exhaust system inspection

Conclusion: Why servicing is an investment, not a cost

Regular servicing keeps your car reliable, safer to drive, and cheaper to run over time. It helps prevent breakdowns, reduces the risk of costly repairs, and keeps your vehicle performing as it should.

Staying proactive with servicing is one of the simplest ways to avoid unnecessary repair bills and keep your car on the road for longer.
