Frequently Asked Questions

Enquire Now

  • What’s the difference between diesel and petrol engine servicing?

    Diesel engines require different servicing due to their fuel systems, filters, and compression levels. They often need more frequent fuel filter and injector servicing to maintain performance.

  • How do I know if my diesel engine needs a service?

    Signs include hard starting, black smoke from the exhaust, reduced fuel economy, loss of power, or unusual engine noises. Regular servicing can help prevent bigger issues down the track.

  • How often should a diesel vehicle be serviced?

    Most diesel vehicles should be serviced every 10,000 to 15,000 kilometres, depending on the manufacturer’s guidelines and how the vehicle is used—especially if it's for towing or long-distance driving.
