Satisfied Client Stories
I have known George and his team for over 15 years and highly recommend. We have eliminated our vehicle down time with dieseltec fleet schedule maintenance
Dieseltec is my first point of contact for all my transport mechanical and electrical needs
We use Dieseltec for all our major repairs as we carry out our general servicing. The guys have the knowledge pin pointing a fault with experience on all vehicles and a fast turn around getting our vehicles back on the road
We moved our Fleet maintenance over to George and the team at Dieseltec 10 years ago due to the incompetent mechanics we had been using in the past, since then we have saved massively on repairs due to the minimisation of breakdown and down time of our fleet
