FAQs

  • How often should I service my diesel vehicle?

    Diesel vehicles should typically be serviced every 10,000 to 15,000 kilometres or every six months—whichever comes first. However, this may vary based on vehicle use and manufacturer guidelines. Regular servicing helps detect early issues, maintains performance, and prevents costly repairs over time.

  • What are the signs my vehicle needs mechanical attention?

    Warning signs include strange engine noises, dashboard lights, poor fuel efficiency, reduced braking power, or unusual vibrations. These symptoms may point to underlying mechanical issues. Ignoring them can lead to further damage, safety risks, or breakdowns—so it’s best to have them inspected promptly.

  • Why is preventative maintenance important?

    Preventative maintenance helps identify and fix minor issues before they become major problems. It keeps the vehicle running efficiently, improves safety, and lowers long-term repair costs. Regular checks of fluids, belts, brakes, and suspension extend the life of your vehicle and minimise the risk of breakdowns.
