LPG Autogas in Australia: Station Availability, Running Costs & Future Trends

Twenty years ago, LPG (Liquid Petroleum Gas / Autogas) was the darling of the Australian motoring scene. Backed by generous federal conversion rebates, cheap pump prices around 40c to 60c per litre, and hundreds of thousands of dual-fuel Ford Falcons, Holden Commodores, and taxi fleets, you could find an LPG bowser at virtually every corner servo in the country. Today, finding a functioning LPG nozzle feels like searching for a needle in a haystack.

1. Why Are Servos Removing LPG Bowsers?

The decline of LPG autogas in Australia was swift and structural:

• End of Australian Car Manufacturing: When Ford closed its Broadmeadows plant in 2016 and Holden ceased Adelaide production in 2017, factory-fitted dedicated LPG engines (like the legendary Ford EcoLPi) vanished from showrooms.
• Taxi Fleets Switched to Toyota Hybrids: Commercial taxi and rideshare fleets rapidly traded their gas-guzzling Falcon sedans for ultra-efficient Toyota Camry and Prius hybrids, destroying overnight the high-volume commercial customer base that kept LPG pumps profitable.
• The 10-Year Tank Recertification Cost: Underground LPG storage vessels require mandatory statutory recertification every 10 to 15 years, costing retailers between $25,000 and $50,000 per site. For low-volume sales, major retail chains like Ampol, BP, and Shell made the commercial decision to dig up the tanks entirely and repurpose the forecourt space for high-power EV chargers or high-flow commercial diesel bowsers.

2. Advice for Current Dual-Fuel Vehicle Owners

If you still drive an LPG-equipped 4WD or classic Commodore, you can still find autogas in major metropolitan industrial areas and along key freight corridors. However, you must never embark on regional road trips assuming rural roadhouses will have gas available. Always keep your secondary petrol tank at least half-full and use FuelPapa’s fuel-type filter to verify active LPG bowsers before you depart.

3. Tank Inspection & Maintenance Mandates

Under Australian Standard AS/NZS 1425, all automotive LPG fuel cylinders must be physically pressure-tested and certified every 10 years by an authorized gas inspection station. Operating a vehicle with an expired LPG tank certification voids your third-party property and comprehensive insurance in the event of an accident.

4. Dual-Fuel Engine Health: Why Running Petrol Matters

Many drivers of dual-fuel vehicles make the mistake of running exclusively on LPG for months on end to save money. This causes serious mechanical issues:

• Fuel Injector Gumming: Stale unleaded petrol sitting in the secondary petrol tank deteriorates and varnishes the petrol fuel pump and injectors.
• Valve Seat Recession: LPG burns hotter and drier than unleaded petrol, lacking natural liquid lubricating properties. In engines without hardened valve seats or electronic upper-cylinder lubricant injection (such as Flashlube), running exclusively on gas causes premature valve recession.

Rule of Thumb: Run your vehicle on pure unleaded petrol for at least 50 kilometres every two weeks to keep fuel lines primed and seals conditioned.
