What Our Customers Say

Maddison Macartney

Thanks to Flash Diesel for making driving fun for me again. After the work done on my Cruiser, I noticed great improvement in the acceleration and the vehicle’s ability to maintain a speed of 100 Km/h when towing. I couldn’t have asked for any more improvement. I will definitely recommend.

I’ve had some towing issues with my Colorado for a while now, and it has seen 2 other workshops in the past 2 months. However, my last stop was Flash Diesel, who was able to diagnose the problem swiftly, explain the solution in simple terms and resolve my concerns within half a day. Thank you
