How often should I change my car’s engine oil?

For most modern cars, engine oil should be changed every 5,000 to 7,500 miles when using full synthetic oil, although some vehicles can go 10,000 to 15,000 miles between changes. Cars using conventional oil may need an oil change every 3,000 to 5,000 miles. Depending on the vehicle, oil should also be changed at least every 12 months.

Driving conditions such as frequent short trips, stop-and-go traffic, extreme temperatures, or towing can mean more frequent oil changes are needed.

For the most accurate interval, check your car’s owner’s manual or speak to a qualified mechanic.

When do I need to replace my car battery?

Most car batteries last around three to five years, depending on factors such as climate, driving habits and battery type.

If your battery is approaching the three-year mark, consider having it tested, especially before winter. Extreme temperatures, both hot and cold, can affect battery performance and shorten its lifespan.

How often should I rotate my tyres, and why?

You should swap your front and rear tyres around every 5,000 to 8,000 miles, or as recommended by your manufacturers.

Regular rotation helps ensure even tyre wear, extends the tyres life, and improves handling and safety.

What does the ‘check engine’ light mean, and is it safe to drive?

If your check engine light pops up on your dashboard, it indicates a potential engine, exhaust or emissions problem.

If the light remains lit up and your car feels normal, arrange a diagnostic check promptly. If it flashes, pull over safely, switch off the engine, and seek professional assistance to prevent serious damage.

How often should I replace my car’s brakes?

Brake pads typically need replacing every 30,000-70,000 miles, depending on your driving habits and road conditions.

Squealing or grinding noises, vibrations, or longer stopping distances are signs your brakes need inspecting as soon as possible.
