How to Cut Car Costs: DIY Maintenance Advice from Justin Tettis, GM at Speed Parts

As the cost-of-living crisis continues to impact Aussie households, more drivers are putting off essential car maintenance. What might feel like a small saving now can end up costing big later. To help navigate this, we caught up with Justin Tettis, General Manager of Speed Parts, who shared practical, budget-friendly DIY maintenance tips. From debunking myths to pointing out which jobs you can handle at home, Justin offers advice that could save you both money and headaches down the road.

The Top Three Maintenance Tasks Aussies Delay (and Why They Matter)

When money gets tight, vehicle maintenance is often one of the first things to be postponed. But according to Justin Tettis from Speed Parts, putting off certain jobs can come back to bite you—hard. Below, he breaks down the top three tasks Australians delay and why avoiding them can turn into a much bigger problem.

1. Timing Chain Replacement

This one isn’t cheap, which is why many drivers put it off until it’s absolutely necessary. But Justin says that’s risky:

“Timing chain replacement is expensive, and since timing chains don’t typically fail suddenly, drivers may overlook it unless they hear rattling noises or the engine runs rough. It’s also a complex job that isn’t top-of-mind unless explicitly advised during a service.”

He also makes it clear what’s at stake:

“A worn timing chain can cause serious engine damage if it fails, potentially resulting in bent valves, damaged pistons, or a complete engine rebuild. This turns a delayed maintenance task into a catastrophic and costly repair.”

2. Transmission Service (Fluid Change, Filter Replacement)

It’s easy to skip transmission servicing because it’s not needed as frequently, and there’s a widespread belief that modern cars have “lifetime” fluids. Justin clears that up:

“Transmission services, like fluid and filter changes, are often delayed because they’re less frequent (every 60,000 to 100,000 km, depending on the vehicle) and are sometimes perceived as ‘optional.’ Some drivers also assume modern cars with ‘lifetime’ transmission fluids don’t need servicing at all, which can be misleading.”

He adds that skipping this could lead to major repairs:

“Old, degraded transmission fluid can lead to overheating, slipping gears, or transmission failure. Transmission repairs or replacements are among the most expensive fixes; therefore, regular servicing is crucial to avoid incurring potentially massive costs.”

3. Oil Changes and Filter Replacements

Because delayed oil changes don’t always cause instant problems, many drivers push them off. But Justin says that’s a mistake:

“People may not immediately notice the effects of delaying an oil change, as the car will still run for a while. With the perception that ‘it’ll be fine for now,’ it becomes easy to push back, especially when budgets are tight.”

But the long-term risks are real:

“Delaying oil changes can reduce engine efficiency and increase long-term wear, potentially leading to more costly repairs in the future.”

Justin’s advice makes one thing clear: staying on top of these tasks doesn’t just keep your car running—it can save you thousands.

Busting the Biggest Myths About DIY Car Maintenance

A lot of drivers steer clear of DIY maintenance because of common misconceptions—like thinking today’s cars are too complex or that you need to be a mechanic to do anything under the bonnet. We asked Justin Tettis from Speed Parts to weigh in and set the record straight.

Myth 1: You Need to Be a Professional Mechanic to Perform DIY Car Maintenance

This is a big one, and Justin says it just isn’t true:

“Many routine car maintenance tasks are well within reach for everyday drivers, even without formal training. Jobs like changing oil, replacing air filters, swapping out spark plugs, and even doing brake pad replacements can be done with basic tools and a bit of guidance. With step-by-step instructions, it’s easier than people think!”

Myth 2: Modern Cars Are Too Complicated to Maintain at Home

Modern cars do have more tech, but that doesn’t mean you can’t handle basic tasks. Justin explains:

“While it’s true that newer cars have more advanced electronics, plenty of traditional maintenance tasks are still simple and accessible. Replacing fluids (oil, coolant, brake fluid), changing bulbs, or maintaining tyres are straightforward, even on modern cars. Many Speed Parts customers save money by doing these tasks themselves instead of relying on mechanics for simple jobs.”

In other words, you don’t need a mechanic’s license—just a bit of know-how and a willingness to give it a go.

Your Pre-Road Trip Checklist: Three Must-Do DIY Checks

Planning a road trip is more than just packing snacks and cueing up the playlist—your car needs to be ready too. Justin shares three simple, DIY checks every driver should do before heading off, especially during busy travel periods like Easter.

1. Check Tyre Condition and Pressure

Tyres are the first thing to check, according to Justin, because they affect everything from safety to fuel economy:

“Proper tyre pressure improves fuel efficiency, enhances grip, and reduces the risk of a blowout. Checking the condition (including tread depth and looking for cracks or bulges) ensures your tyres can handle long-distance driving.”

Here’s how to do it at home:

“Use a tyre pressure gauge (available at Speed Parts) and inflate to the recommended PSI, usually found in the owner’s manual or on the driver-side door frame. Don’t forget to check the spare tyre too!”

2. Inspect Fluids: Oil, Coolant, and Washer Fluid

Long trips mean more stress on your engine, so fluids need to be in top shape. Justin explains:

“Engine oil keeps the engine lubricated and running smoothly, while coolant prevents overheating—a common issue during long drives. Topping up washer fluid is also essential for keeping your windscreen clear.”

Some simple DIY advice:

“Check the oil level using the dipstick, inspect coolant levels when the engine is cool, and top up as needed. If the oil looks dark and dirty, consider doing a quick DIY oil change before you leave.”

3. Test Battery Health

A dead battery can quickly ruin a road trip, so Justin recommends checking it before you go:

“A weak battery can leave you stranded, especially if you’re stopping and starting the engine frequently during your trip.”

You don’t need much to check it:

“Look for corrosion on the battery terminals and clean them if necessary. If your battery is over 3–4 years old, use a battery tester or multimeter to check the charge. Speed Parts also offers affordable battery replacements if needed.”

Doing these quick checks can go a long way in making sure your trip is smooth and stress-free.hances of encountering inconvenient or costly vehicle problems, ensuring a stress-free road trip.

Affordable Parts That Make a Big Difference—Justin’s eBay Picks

Car maintenance doesn’t always need to come with a hefty price tag. In fact, a handful of low-cost parts can make a noticeable impact on your vehicle’s performance, comfort, and safety. According to Justin Tettis from Speed Parts, you don’t need to spend big to take good care of your car—especially if you know where to shop.

1. Air and Cabin Filters

They might not seem like a priority, but changing your air and cabin filters can make a big difference—and it’s one of the easiest DIY tasks to knock out at home.

“Replacing air filters improves engine efficiency and fuel economy, while cabin filters keep the air inside your car fresh and free of dust, pollen, and pollutants.”

A common misconception is that these parts are expensive, but Justin explains that’s not the case when you buy smart:

“You can find quality aftermarket air and cabin filters for under $20, which is a fraction of what it might cost at a dealership.”

So not only are you breathing cleaner air and helping your engine run better, you’re also saving quite a bit just by sourcing the parts online.

2. Oil Filters and Oil Change Kits

Oil changes are essential to keep your engine in good health, and doing them yourself can seriously reduce your annual car expenses. Justin encourages drivers to take this job into their own hands:

“Regular oil changes are essential for engine health, and doing it yourself can save hundreds of dollars annually.”

He points out that top-tier brands are easy to find online—and a lot more affordable than you might expect:

“Oil filters from brands like Ryco, K&N, or Bosch are widely available on eBay for under $10, along with oil change kits that include filters and sump plugs.”

These DIY kits make the job straightforward, and when you compare the cost to what most mechanics charge, the savings really stack up.

3. Wiper Blades

When it comes to safety, visibility is key—especially during wet or unpredictable weather. Replacing worn-out wipers is one of the quickest ways to boost safety, and it’s something many people overlook until it’s too late. Justin explains why it’s worth staying ahead:

“Clear visibility is crucial, and worn-out wiper blades can leave streaks and reduce safety, especially during unexpected rain.”

Rather than waiting for your mechanic to point them out, Justin suggests buying replacements yourself and swapping them out as needed:

“You can pick up replacement wiper blades starting at around $10–$15 per pair, often with free shipping.”

Not only is it affordable, but it’s also a no-fuss job you can do in minutes—with an instant improvement to driving safety and comfort.

With just a few low-cost parts—most of which you can find easily on eBay—Justin shows that DIY car maintenance is more achievable than ever. It’s not about doing everything yourself all at once, but knowing which simple changes can give you the most bang for your buck. Whether it’s cleaner air, better fuel economy, or improved visibility, these easy upgrades are proof that a little effort (and smart shopping) goes a long way.cantly enhance their vehicle’s safety and reliability without the costs associated with dealership servicing, making regular maintenance achievable for everyone.

The Easiest and Safest DIY Car Jobs for Beginners

If you’re new to working on cars, even the idea of popping the bonnet can be a little intimidating. But according to Justin Tettis from Speed Parts, there’s no need to be nervous—there are plenty of simple, beginner-friendly tasks you can confidently do yourself, even with minimal tools or experience.

Whether you’re looking to save some money or just want to learn the basics, these easy jobs are a great place to start.

1. Check and Top Up Fluids

Fluids are the lifeblood of your vehicle, and making sure they’re at the right levels is one of the easiest (and most important) maintenance steps you can take. Justin explains:

“Check your car’s engine oil, coolant, windshield washer fluid, and brake fluid levels. Top them up if needed. Proper fluid levels keep your engine running smoothly, prevent overheating, and improve visibility on the road.”

You don’t need a full toolkit either—just a few basics:

“Just a funnel and maybe some gloves. Your owner’s manual will guide you on where each fluid is located.”

2. Check Tyre Pressure and Tread Depth

Tyres are critical to how your car performs, and they play a huge role in safety. The good news? Checking them is dead simple. Justin says:

“Use a tyre pressure gauge to check your tyre pressure and a coin to measure tread depth (in Australia, use a 20-cent coin—if the platypus’ bill is visible, it’s time for new tyres). Correct tyre pressure improves fuel efficiency, handling, and tyre lifespan, while good tread depth ensures safe grip on the road.”

It takes just a few minutes and could help you avoid a flat or a costly replacement.

3. Replace Windshield Wipers

Wipers often get overlooked until you’re stuck in a downpour, but replacing them is one of the easiest upgrades you can do at home. Justin breaks it down:

“Swap out old wiper blades for new ones. Simply lift the wiper arm, slide the old blade off, and clip the new one into place. Clear visibility is crucial, especially in bad weather. Worn-out wipers can cause streaks and reduce visibility.”

No tools needed—just a quick fix that pays off every time it rains.

4. Change Air Filter

Swapping out your air filter is another low-effort, high-reward job that helps keep your engine breathing easy. Justin explains:

“Open the air filter housing (usually just clips or a few screws), remove the old filter, and replace it with a new one. A clean air filter improves fuel economy and engine performance by ensuring your engine gets clean air.”

It’s simple, fast, and can be done with nothing more than a screwdriver (if that).

5. Top Up Windshield Washer Fluid

This one’s often forgotten, but it’s a five-second task that really matters—especially when driving in dusty or bug-prone areas. Justin says:

“Simply pour washer fluid into the washer reservoir under the hood. It keeps your windshield clean, which is vital for visibility—especially useful during dusty drives or after hitting bugs on the highway.”

6. Clean Your Car Inside and Out

Keeping your vehicle clean isn’t just about aesthetics—it actually helps protect it in the long run. Justin breaks it down:

“Wash the exterior, vacuum the interior, and wipe down surfaces with a microfiber cloth and cleaner. Regular cleaning prevents rust, protects your paint job, and keeps the interior looking fresh.”

A clean car isn’t just nicer to drive—it can help preserve resale value, too.

---

These jobs are ideal for beginners. They don’t require fancy tools or a garage setup—just a bit of time and willingness to give it a go. According to Justin, even doing a few of these tasks regularly can help you keep your car in great shape and avoid bigger problems later on.

Real Aussie Savings: How One Dad Cut Costs with DIY

With the rising cost of everyday essentials, more Aussies are looking for ways to ease the financial pressure—and car maintenance is one area where big savings are possible. For Mark, a young dad juggling family expenses, the solution came from doing his own car maintenance using budget-friendly parts from eBay.

Justin Tettis from Speed Parts remembers Mark’s story well and shares how this simple switch to DIY made a real difference.

“Mark regularly drove his family car—a Ford Territory—on weekend trips. When his mechanic quoted him over $1,000 for basic maintenance, he decided to explore DIY options. He visited us at Speed Parts for advice, and we suggested he check eBay for affordable parts.”

With a bit of guidance and determination, Mark took on several car maintenance jobs himself—and the savings were impressive.

Oil Change

Instead of paying the $350 quoted by his mechanic, Mark bought engine oil and a filter from eBay for just $80. He handled the oil change himself in under half an hour.

Replacing Air and Cabin Filters

The original quote for this was $250, but Mark found both filters online for only $45. He swapped them out easily without needing any special tools.

Brake Pad Replacement

Faced with a $400 quote from the mechanic, Mark decided to do this himself too. After buying brake pads online for just $50 and following an instructional video, the job was done—safely and confidently.

Tyre Pressure and Wipers

For added peace of mind, Mark also picked up a tyre pressure gauge for $12 and a new set of wiper blades for $25, making sure his car was ready for road trips.

The result?

“The total savings were remarkable—while the mechanic’s estimate was around $1,000, Mark completed all these tasks himself for about $200. He saved approximately $800.”

But it wasn’t just about the money. Justin says the experience gave Mark something even more valuable:

“Mark was thrilled—not only did he save money, but he also gained confidence in handling basic car maintenance. He shared how the experience made him feel more empowered and less reliant on workshops for simple jobs. Plus, by doing minor maintenance regularly, he could avoid costly repairs down the road.”

Mark’s story shows just how effective and rewarding DIY car care can be. It’s not about becoming a mechanic overnight—it’s about learning a few practical skills that can lead to real financial relief and long-term confidence behind the wheel.

Going Off the Beaten Track? Gear Up for Rugged Travel

With a growing number of Australians opting for adventurous road trips—exploring remote outback locations and With more Australians choosing to hit the road for off-grid adventures—whether it’s the dusty heart of the outback or rugged coastal trails—the way people prepare their vehicles is evolving. These trips demand more than just a packed esky and a playlist. Justin Tettis from Speed Parts explains that proper preparation is essential, especially when help isn’t just around the corner.

As Justin puts it, being self-sufficient can make all the difference:

“On remote outback trips, drivers need to be self-reliant, as help might be hours or even days away. Stocking up on essential tools and maintenance gear can mean the difference between a minor inconvenience and a major breakdown.”

With that in mind, here are some of the key gear and tools he recommends for rugged and remote travel.

1. DIY Maintenance and Emergency Tools

There are a few essentials every traveller should keep in the car, especially when heading into the bush:

• Tailgate Seal Kits “Keep dust, water, and debris out of your rear storage area, protecting your gear even on dusty, corrugated roads.”
• Tyre Repair Kits “These are for quick puncture fixes on the go, essential when remote.”
• Battery Jump Starters “Compact, portable jump starters that can save you when your vehicle’s battery dies in a remote area.”
• Tool Kits “Basic socket sets, spanners, and screwdrivers for handling roadside repairs.”

These items are small investments that could prevent a trip from being cut short—or worse, leaving you stranded.

2. Maintenance Products for Harsh Conditions

Driving through the outback or over rough terrain means your vehicle is exposed to extreme environments. Justin says it’s important to equip your car accordingly:

• Seat Covers “Made from heavy-duty, water-resistant materials, these protect seats from mud, spills, and pet hair, providing a snug, tailored fit.”
• Air Filters “High-performance filters to keep dust and debris from clogging your engine.”
• Coolant and Engine Oil Additives “To prevent overheating and maintain smooth engine operation in hot climates.”
• Anti-Corrosion Sprays “To protect your undercarriage from rust, especially after river crossings.”

These products are tailored for the rough and unpredictable conditions you’ll face once you leave sealed roads behind.

Justin says this growing trend toward rugged travel is changing the way people approach vehicle maintenance:

“As the demand for rugged, remote travel grows, we’ve noticed customers focusing heavily on preparedness and self-reliance. Whether it’s a family heading to the Simpson Desert or a couple tackling the Gibb River Road, adventurers want to know their vehicles can handle whatever the outback throws at them.”

So whether you’re planning your first off-road trip or you’re a seasoned explorer, being well-prepared isn’t just smart—it’s essential.

DIY or Mechanic? How to Know When to Call in the Pros

Doing your own car maintenance can be empowering—not to mention a great way to save money. But it’s just as important to know when a job is beyond DIY. According to Justin Tettis from Speed Parts, recognising the signs early can help you avoid turning a small issue into a big (and expensive) problem.

Here’s how to tell the difference between a task you can handle yourself and one that should be left to a qualified mechanic.

Red Flags: When to See a Mechanic

Some issues are best left to professionals. If you run into any of the following, it’s time to book your car in for a proper inspection.

Complex Dashboard Warnings
Justin says don’t ignore those lights on your dash:

“If your vehicle’s dashboard lights up with warning signals like the check engine light, ABS warning, or airbag light, it’s often a sign of deeper problems that require diagnostic equipment and professional expertise.”

Leaking Fluids or Strange Noises
If something’s dripping or your car sounds off, take it seriously:

“If you notice oil, coolant, or transmission fluid pooling under your car or hear unusual noises like grinding, knocking, or squealing, it’s time to assess the situation carefully. Leaking components often indicate worn seals, damaged hoses, or failing parts.”

Brake or Steering Issues
These are safety-critical systems. Don’t take risks:

“If your brakes feel spongy, make grinding noises, or pull the vehicle to one side—or if your steering becomes loose or unresponsive—don’t delay. Brake and steering systems are critical, and improper repairs can lead to serious accidents.”

Advanced Engine Repairs (Timing Chains, Transmission)
Some jobs require precision tools and in-depth experience. Justin stresses:

“Repairs involving timing chains, transmission work, or engine components often require specific tools, experience, and precision. Mistakes here can be extremely costly and may lead to engine failure or dangerous driving conditions.”

Green Lights: DIY-Friendly Tasks

While some problems need a pro, many regular maintenance jobs are totally doable at home—even for beginners. Justin lists a few that are safe and straightforward:

• Replacing air filters and windshield wiper blades
• Changing spark plugs and engine oil
• Inspecting and maintaining tyres
• Installing seat covers, strut kits, or tailgate seal kits

And his advice is simple but important:

“By recognising these red flags and knowing your limits, you’ll make more intelligent choices about when to tackle a job yourself—and when it’s time to book in with a professional mechanic for peace of mind and safety.”

---

Knowing when to step back and let a mechanic handle the heavy lifting is part of being a smart, confident car owner. It’s all about balance—doing what you can safely, and trusting the pros when the stakes are high.

Justin’s Personal Road Trip Prep Ritual

For Justin Tettis, General Manager at Speed Parts, road trip prep isn’t something he leaves to chance. Years of experience have taught him that a smooth journey starts long before the ignition turns. Whether it’s a quick weekend escape or a cross-country trek, Justin follows a consistent pre-trip routine to make sure everything goes off without a hitch.

Here’s how he gets road-trip ready—step by step.

---

Step 1: Check the Basics

Justin always kicks things off by inspecting key components and topping up the essentials:

“I make sure the key components of my vehicle are in top shape—checking tyre pressure (including the spare), inspecting for any wear or damage, and topping up essential fluids like engine oil, coolant, windshield washer fluid, and brake fluid. I also inspect the battery connections and ensure it’s fully charged. Nothing ruins a trip like a dead battery.”

He also keeps the essentials packed and within reach:

“I always keep a basic toolkit, jumper cables, and a Tailgate Seal Kit handy, especially when heading off-road, to keep dust and water out of the storage area.”

---

Step 2: Comfort and Convenience

Little comforts can go a long way on long drives. For Justin, these thoughtful touches help make the trip more enjoyable:

“Seat covers are a lifesaver, keeping seats clean—especially if pets or outdoor activities are involved. I also install an Up and Down Strut Kit, which makes opening and closing the tailgate effortless when loading up luggage, camping gear, or snacks. I always keep a sun visor handy and use a reflective sunshade to keep the cabin cool during breaks.”

---

Step 3: Emergency and Navigation Prep

No matter how well-planned the trip is, Justin always prepares for the unexpected. Here’s how he gets ahead of potential problems:

“I review weather forecasts, road conditions, and planned detours on my route. I pack emergency gear, including a first aid kit, torch, water, non-perishable snacks, and a tyre repair kit for unexpected flats.”

And when travelling through remote areas, he never relies solely on phone signal:

“Mobile reception can be spotty, so I download offline maps of my route on Google Maps ahead of time. It’s a simple step that has saved me more than once when the GPS signal has dropped!”

---

Step 4: Fuel Up and Hit the Road

Finally, once everything is checked and packed, Justin makes sure the car is full and ready to roll:

“I top off the fuel tank, double-check that my emergency gear and snacks are packed, and then I’m ready to enjoy the open road. Whether it’s a scenic coastal drive or an off-road adventure, these checks give me peace of mind to relax and enjoy the trip.”

---

Justin’s prep routine is a great reminder that even small efforts can make a huge difference. With a little time and planning, you can avoid unnecessary hiccups and focus on what really matters—enjoying the drive.
