Smithy's LPG and Automotive Services: The Best Autogas Conversions in Melbourne

Welcome to Smithy's LPG. We offer the best quality LPG gas conversions in Melbourne, and they are backed by a LIFETIME GUARANTEE*

If you are at this website to find the cheapest conversions around, you won't find it here. If you are here to find a mechanic that offers the best LPG gas installations at great prices, you will. This is because at Smithy's LPG & Automotive services, our system selection, and installation is right for your vehicle the first time. We are so confident in this that we are offering an industry leading LPG GAS LIFETIME GUARANTEE* on workmanship and materials!

In fact, you may well have been directed to this website by another installer to acquire accurate information on the most suitable equipment for your vehicle, and a quote on Smithy’s price for a top quality installation. This installer may then have suggested you should return to him for a better price. At Smithy’s we are concerned at this practice, where an installer does not know what equipment to use, or how much to charge, and therefore we guarantee you that his installation, tuning and back up service will not be up to Smithy’s standard.


When we install LPG injection systems, we provide a LIFETIME GUARANTEE* ON PARTS AND LABOUR. Our autogas injection systems are tuned on a state of the art all-wheel drive dyno dynamics LPG gas dynamometer, from which you will receive the before and after graphs showing the power and torque of your autogas injection system. No other LPG installer in Melbourne can offer both these features.

The quality of our LPG conversions start with the information provided on this website, and continues through the quotation, installation and service life of the vehicle, and our confidence is supported by a Lifetime Guarantee from a company that has been in business for a quarter of a century.

Here at Smithy’s LPG, we have been providing Melbourne Autogas conversions for the last 25 years and we believe that there is no substitute for quality. We install the injection system that is right for your car and we have professionally qualified technicians for each system. We are VACC and RACV accredited and we provide aftercare and a free complimentary LPG service. We also offer a full range of mechanical services to keep your vehicle in ‘Tip Top’ condition.
