Most people don't realise how much a failing EGR valve is costing them until it's too late.

The Exhaust Gas Recirculation (EGR) valve is designed to reduce emissions - but on American diesel trucks, it's one of the most common causes of:

→ Increased fuel consumption
→ Black smoke under load
→ Rough idling and hesitation
→ Loss of power under tow

A clogged or stuck EGR won't always throw a code early. That's the problem. By the time the light comes on, carbon buildup can already be significant.

We diagnose and service EGR systems on Powerstroke, Duramax and Cummins engines. If your truck doesn't feel right, don't ignore it.

Winter in Queensland might be mild compared to the southern states - but for a diesel engine, the cooler mornings still matter.

Here's what we see more of every Winter:

→ Glow plug failures showing up that were borderline all summer
→ Batteries that cope in the heat, dying in the cold
→ Injector seals that weren't leaking in warm weather, suddenly are

These aren't random failures. They're predictable. And a pre-winter check is a fraction of the cost of fixing them roadside.

It's EOFY season. And if you're a business owner running an American diesel truck - or a fleet of them - this is the time to get any outstanding repairs or maintenance done before 30 June.

Servicing, diagnostics, part replacements - these are all legitimate business expenses. Don't leave money on the table by rolling into the new financial year with deferred maintenance.

We're booking out fast in June. Call us now to lock in your appointment.

Michael originally started his business as a field service operation - mining belts, gas fields, heavy equipment across Central Queensland.

When he brought the business back to Toowoomba as MS Mechanical, he brought everything he'd learned in those conditions with him. The diagnostic discipline. The attitude that no job is too hard. The understanding that a broken-down vehicle isn't just an inconvenience - it's a real problem for real people.

That's still what drives the workshop today. We just happen to do it now with some of the best diesel trucks on the planet.

If you're local, come in. If you're not, we're worth the drive.

Not every day you get a piece of American history rolling into the workshop.

This is the limited edition Harley-Davidson F-150 - built to celebrate 105 years of one of the most iconic motorcycle brands on the planet. Ford and Harley-Davidson have had a collaboration going back decades, and this truck is exactly what you'd expect when two American icons get together.

Blacked out, badged up, and built to turn heads.
It came in to see us here at MS Mechanical - and we took a moment to appreciate it before we got to work.

This is exactly the kind of vehicle we love seeing in the workshop. Unique, American, diesel-capable, and with a story behind every badge.

Own something special? We treat it that way.

The American truck market in Australia isn't slowing down.

But the service infrastructure still hasn't caught up. Most workshops don't have the diagnostic software. Most don't have parts connections with international suppliers. Most haven't spent years learning the quirks of a 6.7L Powerstroke or a Duramax.

We have.

If you're in the Darling Downs or surrounding region and you own a Ram, Ford, Chev or GMC - you've got a specialist workshop in your backyard. Most truck owners in this country aren't that lucky.

Come and see us.

If fuel prices have you watching the gauge more closely, here are 5 things that directly affect how much diesel your truck is burning through - and that we can actually fix.

▪️Dirty or worn fuel injectors - poor spray pattern means incomplete combustion. More fuel in, less power out.

▪️EGR valve issues - a stuck or clogged EGR forces the engine to work harder than it needs to.

▪️DPF struggling to regenerate - a partially blocked filter creates back pressure that kills efficiency.

▪️Turbo underperforming - if boost pressure is down, the engine compensates by using more fuel.

▪️Air filter and intake restriction - one of the simplest fixes, and one of the most overlooked.

Any of these sound familiar? Drop your question below or book in for a diagnostic.

Here's something a lot of F-150 and Super Duty owners don't know - and it could save you from a costly mistake.

If you're running a pre-2020 Powerstroke and you've been looking at upgrading to the newer steel piston components, there's an important compatibility issue you need to understand before you spend a cent.

Michael breaks it down here in plain language. This is exactly the kind of specialist knowledge that separates a workshop that really knows these trucks from one that's just guessing.

If you've got questions about your Powerstroke after watching, drop them in the comments or give us a call.

We don't talk about our work as much as we probably should.

So we'll let this Google Review do it instead.

If you've got an American diesel truck in Queensland and you've been told it's too hard, too specialised, or too much of a problem - call us. That's exactly the type of challenge we love.

Winter is just around the corner, and cold starts are harder on diesel engines than most people realise.

Here's what we're checking on every American diesel truck this month:
→ Glow plugs - the first thing to show weakness in cold weather
→ Battery health - diesel cranking demands are serious. Over 3 years old? Get it tested. → Coolant condition - not just the level, but whether it's still doing its job
→ Injector seals - small leaks accelerate in the cold. White smoke on start-up is a sign. → Transmission and diff fluids - cold thickens everything and can hide early wear

A pre-winter check now is a lot cheaper than a breakdown in the colder months.
