A Real Workshop Case Study from Combined Automotive Services Even the toughest vehicles can run into problems when the wrong fuel finds its way into the tank... The Problem Recently at Combined Automotive Services in Milton, our team dealt with a Toyota Hilux that arrived with a classic but frustrating issue — contaminated fuel. While the Hilux has a reputation for reliability and toughness, poor quality or contaminated petrol can cause a range of performance problems that need professional attention.       This particular repair is a good example of how experienced technicians approach fuel-related issues step by step to restore reliability without risking further damage to the engine. When a Tough Hilux Starts Acting Up What will kill a Hilux petrol? Well… apparently not even terrible fuel! This tough Hilux spent a couple of months relaxing at the airport while its owner was overseas. When she returned? Rough idle, hard starting, and a very unhappy engine. The vehicle had been sitting unused for an extended period, and shortly after it was started again, it became clear that something was not right. The engine struggled to start properly and once running it idled unevenly and lacked the smooth performance the owner was used to. Recognising that something serious might be going on, the owner had the vehicle towed straight to Combined Automotive Services in Milton for professional diagnosis. Step 1: Initial Inspection and Diagnostics When a vehicle arrives with symptoms such as rough running or starting difficulties, the first step is always a thorough inspection. At Combined Automotive Services, our technicians begin by gathering information from the customer and reviewing the symptoms being experienced. In this case the signs included: Rough idle Hard starting Poor engine performance Using professional diagnostic equipment, our technicians then checked the vehicle’s systems to rule out common faults such as ignition issues, sensor problems, or fuel delivery faults. A quick round of diagnostics and—boom—diagnosis confirmed: contaminated fuel. Yep… the Hilux was basically trying to run on iced coffee instead of 91. While bad fuel might sound simple, it can cause significant issues inside a modern fuel system if not dealt with correctly. Step 2: Identifying the Source of the Problem Fuel contamination can happen in several ways. Sometimes it’s caused by water entering the fuel tank, sometimes by degraded fuel after long periods of storage, or occasionally by contaminated fuel from a service station. Because this Hilux had been sitting unused for a few months, the most likely cause was degraded or contaminated fuel sitting in the tank. Before any repair work is carried out, our technicians carefully confirm the condition of the fuel and assess the potential impact on the vehicle’s fuel system components. Modern engines rely on very precise fuel delivery, and even small contaminants can affect how the engine runs. Step 3: Removing the Contaminated Fuel Once the problem was confirmed, the next step was to remove the contaminated fuel safely. This process must be carried out by trained professionals because modern fuel systems operate under pressure and require the correct procedures and equipment to avoid damage or safety risks. The bad fuel was completely flushed out of the system to prevent further contamination of the fuel lines, injectors, and pump. Removing contaminated fuel is one of the most critical stages of the repair because leaving even a small amount behind can cause the problem to return. Step 4: Replacing Key Fuel System Components With the contaminated fuel removed, the next step involved replacing the fuel filter. Fuel filters play a vital role in protecting the engine by trapping contaminants before they reach sensitive components such as fuel injectors. Once contaminated fuel passes through the system, replacing the filter helps ensure that any remaining debris does not continue circulating. Installing a new filter helps restore proper fuel flow and protects the engine moving forward. Step 5: Cleaning and Protecting the Fuel System After the system was flushed and the filter replaced, the team at Combined Automotive Services added a fresh tank of clean fuel. To complete the process, a professional BG fuel system treatment was used to clean internal fuel system components and provide additional protection. These treatments are designed to help remove deposits and residue that may remain after contamination, ensuring that injectors and other components continue to operate efficiently. Step 6: Final Testing and Performance Checks Once the fuel system had been cleaned and refilled, the Hilux underwent final checks and testing. The technicians ran the engine, monitored performance, and ensured that the previous symptoms had been resolved. This testing stage confirms that the repair has been successful and that the engine is operating as it should. The results? Smooth running, easy starting, and one Hilux back in business. The Importance of Professional Diagnosis Fuel contamination can sometimes appear similar to other mechanical issues, which is why professional diagnostics are so important. Without proper testing and inspection, it is easy to misdiagnose symptoms like rough running or hard starting, potentially leading to unnecessary repairs. At Combined Automotive Services in Milton, our experienced technicians use the correct diagnostic tools and proven workshop processes to accurately identify problems and carry out the necessary repairs. Back on the Road Turns out, even bad fuel can’t keep a good Hilux down—as long as you bring it to the right workshop. After the repair process was completed, this Toyota Hilux was back to starting easily, running smoothly, and performing exactly as it should. Combined Automotive Services — keeping Brisbane’s toughest cars even tougher.

While the Hilux has a reputation for reliability and toughness, poor quality or contaminated petrol can cause a range of performance problems that need professional attention.

Cabin or Pollen filters are your invisible line of defence against allergens inside your car, working to filter out irritants that can trigger allergic reactions. At Combined Automotive Services in Milton, we recommend having your filters checked and replaced regularly to ensure a safer and more comfortable drive. Anyone who suffers from allergies knows that just because spring has passed, it doesn’t mean the discomfort has disappeared. While it’s well-known that spending time outdoors can expose you to allergens, fewer people realise that the air inside your car can be significantly more polluted than the air outside. It can contain harmful bacteria, dirt, pollen, fungi, and the unavoidable summer dust that often finds its way into our vehicles. These contaminants can enter the passenger cabin unfiltered through the vehicle's air intake system, potentially causing allergies, asthma, headaches, nausea, fatigue, or dizziness. Needless to say, none of these are ideal when trying to enjoy a drive or focus on the road ahead Thankfully, there are ways to mitigate these risks. One simple and effective measure is ensuring that your cabin air filter is in good condition. Most vehicles manufactured since the late 1990s come equipped with a cabin air filter. At Combined Automotive Services in Milton, we are proud to recommend and install high-quality Ryco Filters, which are designed to effectively trap pollutants and improve air quality inside your car. What many drivers don’t know is that a clogged or worn-out cabin air filter can also affect your car’s air conditioning system. When the filter becomes blocked with debris, it can reduce airflow, causing your air conditioning to work harder and possibly even consume more fuel. Replacing the filter not only enhances the air quality but also helps maintain the efficiency of your vehicle's ventilation system. For a clean, fresh, and more comfortable ride, visit us at our workshop and let our team ensure your cabin air filter is up to the task.

Reduce allergens, dust, and pollutants in your car with quality cabin air filters. Ensure a healthier, more comfortable drive while maintaining your vehicle’s air conditioning efficiency.

Air Filters and Allergies

Motor oil is the most important fluid in your car after fuel—but what keeps it clean? Your car's oil filter cleans the oil multiple times per minute, removing solid particles of dirt, carbon, and metal fragments. If left unchecked, these contaminants can damage bearings and cylinder wall surfaces, increase engine wear, and shorten your engine's lifespan. Combined Automotive Services are experts in maintaining the health of your vehicle's systems, ensuring they work at their best.   Replacing oil filters regularly is essential to protect your engine's life and sustain optimal performance. While manufacturers provide guidelines for when filters should be changed, the actual timing depends on various factors, such as driving conditions, filter age, engine age, and mileage. Ideally, oil filter changes should follow the logbook schedule at a minimum, but it’s often better to replace them sooner if needed. One thing is clear: routine oil filter replacement helps safeguard your engine and oil, ultimately saving you money by preventing expensive repairs in the long run. Don't forget that oil filters should always be replaced when the engine is flushed as it has collected debris and contaminants which shouldn't be reintroduced into clean engine oil. At Combined Automotive Services, we recommend checking and replacing the oil filter during every full car service. Regular checks not only keep your car running smoothly but also provide peace of mind.   Did you know? A clogged oil filter can cause the oil pressure warning light to illuminate on your dash, as the filter restricts the flow of oil through the engine. This is another reason why keeping your oil filter in top condition is so important.   We offer logbook services and much more for a wide range of makes and models, all conveniently located right here in Milton. Call us today to discuss your car and its last service, and we'll provide you with a quote.

Oil Filters

Your vehicle is equipped with several different filters, each designed to function within a specific system in your car. At Combined Automotive Services, we understand these systems thoroughly and provide expert servicing in Milton and the surrounding areas. Put simply, filters work to trap particles that could cause damage or don’t belong in the system they’re protecting. However, all filters have a limited lifespan – once they become clogged with the particles they’re designed to capture, they must be replaced. Failing to replace filters when needed can lead to costly damage in critical parts of your vehicle. Types of Filters in Your Car Include: Oil Filter: Ensures the engine oil remains clean and flows efficiently through the engine, preventing wear and tear.
Air Filter: Blocks dirt, debris, and particles from entering the engine that could harm cylinders, pistons and other internal components.
Cabin Air Filter: Protects the car’s ventilation system by filtering out pollen, dust, and bacteria, ensuring clean air inside the vehicle.
Fuel Filter: Prevents contaminants from reaching the carburettor or fuel injectors, helping maintain proper fuel flow and performance.
Transmission Filter: Found in vehicles with automatic transmissions, it removes debris and metal shavings from transmission fluid to protect the gearbox.   Did you know that a clean engine air filter can improve fuel efficiency by up to 10% in some vehicles? Ensuring all filters are in good condition not only safeguards your car’s systems but can also enhance its overall performance.   At Combined Automotive Services, we offer a comprehensive 65 Point Vehicle Inspection Report with every full car service, available upon request. This includes checking your car’s filters to help you avoid costly repairs and keep your vehicle running smoothly.
