With regards to repairs, depending on the availability of parts we can generally return your vehicle in the same day so inconvenience to you is keep to a minimum.

Diesel Gas

Diesel Gas will improve any diesel engines all round performance; it will increase horse power and torque by extracting every last molecule of energy out of the diesel fuel, its makes towing large caravans and boats so much easier. Diesel gas will improve fuel consumption, extend driving range and help keep the engine internally cleaner. It will enhance any diesel performance modification, bigger exhausts, chipping, etc. We recommend the DieselGas Australia system due to its outstanding performance and reliability; however we can service and repair any Diesel Gas system.

Automotive LPG Conversions (petrol engines)

LPG is still the cheapest fuel at the bowser and it always will be because it is much easier to refine than petrol. Auto gas is far less harmful to the environment because it produces fewer emissions than petrol, in fact LPG is the greenest fuel on the market in most areas in Australia, natural gas is the only fuel that burns cleaner. LPG clean burning means a cleaner engine, no carbon deposit in the combustion chamber and no sludge in the crank case, engine oil will last longer on an LPG fuelled engines. Gone are the days where LPG fuelled engines had noticeably less power than petrol, smart electronics has rectified that, most drivers will not feel any performance variation between petrol and LPG but they will notice the huge savings at the bowser. We are the Townsville agent for Lovato auto gas and recommend it due to its reliability and performance; however we can install service and repair any system including LPG liquid injected systems.

Auto Gas Service & Repair

Unless your regular mechanic is LPG certified he legally cannot work on the auto gas fuel system of your vehicle. All LPG motor fuel system will require attention from time to time, in fact most manufacturers of this equipment recommend their systems be serviced every 12 month so the system remains safe and reliable, Diesel Gas Townsville is fully equipped to service, repair or tune the auto gas system on your vehicle. Our rates are resonable and service second to none.

LPG Motor Fuel Certificates/Inspections & Mobile Gas Inspections for Forklifts

At Diesel Gas Townsville we are authorised to carry out LPG motor fuel inspections. Any motor vehicle fitted with an LPG fuel system will require a gas certificate before registration or change of ownership or to pass a road worthy inspection, this applies to cars and trucks. Forklifts fall under a different set of standards but still will require an LPG inspection prior to road registration (if applicable) and will require a 12 monthly gas inspection if under hire. For your convenience Diesel Gas Townsville provide a mobile service for forklifts gas inspections and are certified to repair/service LPG and natural gas fuelled stationary engines.

LPG Cylinder Test Station

Diesel Gas Townsville is qualified to retest/redate all domestic and automotive LPG gas cylinders. We offer a one day turn around service, the cylinder will be returned to you fully resealed and tested, ready for another 10 years of safe and reliable service. We also offer a cylinder disposal service; we can decomission cylinders safely and legally. IT IS AN REQUIREMENT OF LAW THAT LPG CYLINDERS ARE TESTED EVERY 10 YEARS.

Common Rail and High Tech Diesel Diagnostics & Repairs

Common Rail engines and other types of hi tech diesels have been available for several years in cars, utes and 4x4's, generally these engine are very reliable providing they are serviced properly, but when things do go wrong without the correct diagnostic test equipment accurately pin pointing the problem can be difficult and many times expensive parts are replaced that don't fix the problem. Diesel Gas Townsville has invested heavily in expensive test equipment to eliminate misdiagnosis. At Diesel Gas Townsville we will diagnose the problem with your hi tech diesel, replace only the part that is required, and return your vehicle promptly with a guarantee that the vehicle is fixed.

FAQ About Turning your Vehicle to Diesel Gas

Click on the question to go directly to the relevant answer.

  1. LPG and Diesel together? Can this really be done?

    Yes. In the trucking industry, mechanical LPG systems have been available for decades now. These systems were designed for 400+hp engines. A proper system has been available for smaller diesel vehicles since mid-2004 thanks to modern electronics providing the means to meter and control such small amounts of gas.

  2. Is it safe?

    Yes, probably safer than most petrol systems. We've never had a failure. Our kits use tried and tested components that have been used in LPG conversions for many years. They are fitted to Australian Standard AS1425, one of the most stringent LPG fitting standards in the world.

    The system operates like a typical car fuel injection unit. The control valve and gas lock-off valves are designed to shut off gas flow at both the tank and engine in idle mode, as soon as the brakes are applied, and in the event of any malfunction.

  3. Is the system reliable?

    Yes. The results speak for themselves. The trucking industry has had mechanical LPG systems for decades now, although these were systems designed for 400+hp engines. With the advent of modern electronics, smaller amounts of gas can now be controlled. A proper system designed specifically for smaller diesel vehicles has have been available since mid-2004.

  4. Will the extra power damage my engine?

    No. Your engine will now burn the entire amount of diesel injected and will run cleaner with no soot build-up. This means that your engine oil will stay cleaner longer and will more effectively extend your engine's life. As with any performance or economy modification, your engine needs to be in good condition in order to maximise the benefits.

  5. What if I can't get LPG? Or I run out of gas?

    No problem. You won't even need to switch the system off. The system doesn't affect diesel injection functions, so your vehicle will continue to run on diesel as it did before the Diesel/Gas system was fitted. You'll notice a decrease in power as the LPG runs out. When you top up the LPG, the system will automatically begin injecting gas again.

    LPG availability is becoming more widespread. It's now possible to drive an LPG-powered vehicle the length of the National Highway.

  6. How long will you need my vehicle to fit the system?

    Most installations take about a day-and-a-half to fit and tune. Extra time may be needed if there is limited space for the LPG tank. Dyno tuning, which is only done at your request, takes an extra half-day.

  7. Will it pay for itself?

    You'll break even on your investment reasonably quickly from the fuel savings. That's aside from the lower maintenance costs thanks to extending your engine's life.

    As a rough guide, the system would pay for itself around 100,000km. The average motorist drives approximately 15,000km a year; articulated trucks, around 83,000km a year. The cost of LPG and diesel, as well as the difference in price between them, help determine the savings. We can calculate your break-even more accurately if we have your vehicle details and current fuel consumption figures.

  8. Where does the LPG tank go?

    The tank is usually mounted underneath the vehicle to avoid encroaching on cargo space. For vehicles with no room underneath or low ground clearance, the tank can be mounted inside (to Australian Standard AS1425). A tank mounted under a vehicle is protected by a steel guard. The exhaust pipe may need to be rerouted in some instances. Other than taking up space, there is no safety issue with fitting the tank inside.

  9. What size LPG tank do I need?

    Typically, the LPG tank is 1/3rd the capacity of the diesel tank — 30 litres of LPG is sufficient for approximately 100 litres of diesel. In a 4WD, one litre of LPG is sufficient for 25 to 30km. Put another way, LPG consumption should be in the range of 3-4 litres per 100km. Tanks come in a range of sizes, so we'll be able to fit one to suit your vehicle's needs.

  10. Does my vehicle have to be de-rated?

    No. One big advantage of this system is that diesel injection is not touched. If you run out of gas you're still good to drive on diesel only (at least until it too, runs out).

  11. What if there's a system malfunction?

    If a fault occurs — e.g. the alternator fails and no longer sends an engine speed signal — the system shuts itself down. As a safety measure to prevent over-fuelling, gas flow is shut down. You can continue driving on diesel only.

  12. Am I better off getting turbo fitted?

    For power and economy, Diesel/Gas is the solution. For performance only, have both turbo and diesel/gas fitted. Diesel/Gas delivers real savings at the bowser, extended range, less engine wear and reduced emissions. Producing extra power in its own right, the system also significantly boosts the gains of any other performance modification. Dyno testing has shown the system will deliver up to 20% more power on top of any other performance gain.

  13. Who can program the computer?

    The computer module can only be programmed by an approved Diesel/Gas Australia installer. This is for engine protection and safety reasons. System installation includes tuning. To maximise the benefits for your vehicle, Dyno tuning is available at an extra cost. System adjustments can be made later, as necessary, and usually take no more than 10 minutes.

  14. Does the engine run hotter?

    No. The engine doesn't need to work as hard, since more power is being produced, so it will not run hotter. Exhaust gases are also cooler because excess fuel is no longer burning off in the exhaust system.

  15. Is extra servicing required?

    Oil should be changed after 1,000km and again at 5,000km. As the engine is being cleaned internally now, the oil will be dirtier at first from the carbon build-up being removed. These 2 oil changes can be done by your usual workshop and no special oil is required. After the first 2 oil changes, normal service intervals can be resumed.

  16. Can the system be fitted to a modern electronically controlled diesel?

    Yes. The system is fitted with its own wiring harness and does not interfere with the electronics found on modern diesels. The diesel injection is not de-rated in any way on either electronic or mechanical engines.

  17. Does Diesel/Gas work with biodiesel?

    Yes. If your engine runs properly on biodiesel, it will certainly handle the Diesel/Gas system. Due to the lower cost of biodiesel, you will achieve equally good performance at cheaper running rates, while your emissions dramatically improve as well.

  18. What guarantee comes with your system?

    Diesel Gas Australia installations are backed by a 3-year Parts, Labour & Engine Warranty. The assurance comes from Elite Warranty, accredited by ASIC (Australian Financial Services Licence #311707) and Australia's largest independent supplier to the automotive industry of wholesale warranty systems.

  19. Why do we inject LPG prior to the turbo?

    When LPG is introduced prior to the turbo, the turbo performs like a mixer, providing consistent and even distribution of LPG vapour with the air. This even distribution ensures that each cylinder receives an equal quantity of LPG vapour and avoids potential engine damage. It maximises power and economy gains while limiting harmful exhaust emissions. The mix of air/LPG passing through the intercooler (if fitted) is not flammable. Even if it were flammable, the delivery of LPG stops immediately if charge air pressure (boost) drops due to common turbo failure or a major leakage of charge air.

    Introducing LPG vapour prior to the turbo requires a constant LPG pressure that is electronically monitored and maintained within a strict operating range. Systems with post- turbo LPG introduction, require constantly changing LPG pressure to overcome charge air pressure. The LPG pressure required in these systems may be equal to, or up to 5 times higher than, a pre-turbo injection. This can result in reduced system safety and erratic LPG delivery in differing ambient conditions.

    Some of our clients with turbo-charged vehicles operating with LPG through the turbo, have heavy goods vehicles, with engines exceeding 600HP, that have travelled more than 1 million kilometres. Not one problem has emerged with any of these engines or turbo chargers caused by LPG vapour. The bottom line is that we do not need to introduce post- turbo, so we do not.
