About Peninsula Diesel
Who We Are
Peninsula Diesel Repairs is a family-owned business that’s been trusted by operators across the Mornington Peninsula and Melbourne’s South East for more than 30 years. Run by the Sutherland family, we’ve grown from a modest workshop into one of the region’s leading diesel service specialists.
We work with local councils, fleet managers, bus companies and business owners—anyone who depends on diesel vehicles and equipment to get the job done. Our Mornington workshop is fully equipped and purpose-built for diesel diagnostics, repairs, and servicing. Whether you run a single truck or manage an entire fleet, we’re here to keep you moving.
Our team of qualified mechanics is backed by decades of real-world experience. We understand the pressures of keeping vehicles on the road, and we know the difference reliable servicing can make.
How We Work
At Peninsula Diesel, we keep things straightforward. That means no jargon, no delays, and no unexpected surprises. Just honest advice, clear communication, and high-quality workmanship you can count on.
We focus on what actually matters to our customers:
Less downtime
Reliable turnaround times
Upfront, transparent service
Work done right the first time
Our approach is built on long-term relationships, not quick fixes. We’re here to be a trusted partner for your business—someone you can rely on when time is tight and quality matters.
Because when your vehicles are working, your business is working. And that’s what drives us.
