What's Included in a Full Car Service?

Published 2026-03-27 · Park Royal Tyre & Alignment Centre

A full car service covers an engine oil and filter change, a thorough check and top-up of all fluids, an inspection of the brakes and tyres, a battery and electrics test, and a multi-point safety check across the whole vehicle. It is the most comprehensive routine service most cars receive.

What does the oil and filter change involve?

The oil and filter change is the heart of any full service. We drain the old engine oil completely, fit a new oil filter, then refill with the correct grade of oil for your engine. Fresh oil keeps moving parts lubricated, helps control engine temperature, and clears away the grime that builds up over the year.

Old oil thins and fills with contaminants as the miles add up. Once that happens it lubricates poorly, which lets components wear faster and can shorten engine life. Changing the filter at the same time matters just as much, since a clogged filter cannot trap the particles that cause damage.

During a full service we also inspect and, where due, replace the other filters: the air filter, the fuel filter on many models, and the cabin pollen filter. Our car servicing team uses oil that meets your manufacturer's specification, which protects both the engine and your warranty.

Which fluids are checked and topped up?

A full service includes a check of every fluid your car relies on, with top-ups where needed. That means coolant, brake fluid, power steering fluid, clutch fluid where fitted, screen wash and, on some vehicles, transmission fluid. Each one plays a specific role, and a low or contaminated fluid is an early warning of a developing problem.

Think about what these fluids do. Coolant stops the engine overheating, brake fluid lets the brakes respond instantly, and screen wash keeps your view clear in dirty weather. Topping them up is quick, but checking them often reveals more, such as a slow coolant leak or brake fluid that has absorbed moisture and needs replacing.

Why fluid condition matters as much as level

A fluid can be at the right level yet still be past its best. Brake fluid attracts water over time, which lowers its boiling point and can make the pedal feel soft. Coolant loses its protective additives. That is why we look at colour and condition, not just the level on the dipstick.

How are the brakes and tyres inspected?

Brakes and tyres are your two biggest safety items, so both get a careful inspection during a full service. We check brake pad and disc thickness, look for scoring or warping, and examine the brake lines and fluid. Then we inspect each tyre for tread depth, uneven wear, sidewall damage and correct pressure.

Brake wear is gradual, so it rarely announces itself until performance has already dropped. Measuring pad and disc thickness lets us tell you how much life is left and plan ahead rather than reacting to a grinding noise. If pads are close to the limit, we will flag it before it becomes a safety risk.

Tyres tell a story too. Patchy or one-sided wear often points to a wheel alignment that has drifted, while low tread reduces grip in the wet. We will measure tread against the legal limit and recommend any tyre or alignment work separately, so you decide what to do with a clear picture.

What happens during the battery and electrics check?

The battery and electrical check confirms your car will start reliably and that its key electrics work. We test the battery's charge and condition, inspect the terminals for corrosion, and check the charging output from the alternator. We also confirm that the lights, indicators, wipers and warning lamps are all working as they should.

Batteries weaken slowly, especially after cold winters and lots of short trips. A battery can seem fine right up until the morning it will not turn the engine over. Testing it as part of a service gives you warning while there is still time to plan a replacement rather than facing a no-start on the driveway.

If a fault light is showing or something electrical seems off, that points towards a closer look. Persistent warning lamps usually need a diagnostic scan, which sits alongside servicing rather than inside it.

What does the multi-point safety check cover?

The multi-point safety check is a head-to-toe inspection of the components that keep you safe and legal. It covers the suspension and steering, the exhaust system, drive belts and hoses, wipers and washers, all exterior lights, and the condition of the bodywork around safety-critical areas. Anything worn or close to failing gets noted and explained.

This is where a full service earns its keep. Many faults are easy to fix when caught early but expensive once they are left to worsen. A perished hose, a leaking shock absorber or a fraying drive belt can each be spotted on the ramp long before they leave you stranded or cause a knock-on failure elsewhere.

We give you a clear report of what we found, split into what needs attention now and what to keep an eye on. Nothing extra is carried out without your say-so, so you stay in control of any further work and the cost.

What does a full service not cover?

A full service does not cover major repairs or replacement parts beyond filters and consumables. It is a planned maintenance and inspection package, not a repair job. If the inspection finds worn brakes, tyres or a failing component, those are quoted and carried out separately once you approve them.

Frequently asked questions

How often should I get a full service?

Most cars benefit from a full service once a year, or roughly every 12,000 miles, whichever comes first. Check your handbook, as some manufacturers set their own intervals. If you cover low mileage but mostly short trips, an annual service is still wise because the oil ages with time as well as distance.

How long does a full service take?

A full service typically takes a few hours, depending on the vehicle and what the inspection uncovers. If we find work that needs doing, such as worn brakes or a tyre near the limit, we will call you with a quote first. You are welcome to wait or drop the car off, whichever suits.

Will a full service highlight problems before they get worse?

Yes, that is one of its main benefits. By inspecting brakes, tyres, fluids, the battery and the suspension on a schedule, a full service catches wear early. You get a clear report of what needs attention now and what to watch, which helps you budget and avoids surprise breakdowns down the line.
