Graphene Manufacturing Group Ltd. (TSXV: GMG, OTCQX: GMGMF) has launched a new direct-to-consumer website, g-lubricant.com, to sell its graphene-based G® Lubricant, aiming to make a mark in the global liquid fuel industry. The Australian clean-tech company is betting that its graphene liquid concentrate can help both diesel and gasoline engines run more efficiently, and it’s backing up those claims with recent test results and years of research.
G® Lubricant is a graphene-infused liquid concentrate designed to be added to any mineral or synthetic oil used in internal combustion engines. The final lubricant contains only about 0.01% graphene by weight, with the rest being base oil. This low concentration means it can be safely used in a wide range of engines without causing compatibility issues.
Over the last four years, GMG has worked with the University of Queensland to test G® Lubricant under controlled conditions. Their studies found that diesel engines using the product saw fuel efficiency improvements of up to 8.4%. These lab results have been echoed in field tests by customers, who have reported similar savings in both diesel and gasoline engines.
GMG’s strategy is to reach targeted markets directly, while also building awareness through bulk and retail pack options. Beyond direct sales, the company is in talks with potential distributors and original equipment manufacturers in various regions. This approach could help GMG expand its reach quickly, especially in markets where fuel efficiency and emissions regulations are tightening.
In May 2025, GMG put G® Lubricant to the test again, this time using its own company van, a Mercedes Vito with over 360,000 kilometers on the clock. The van was tested at a third-party dynamometer facility, with a focus on both fuel consumption and exhaust emissions.
The results were notable. At a steady 2,500 rpm and 100 km/h, the van’s diesel engine used about 13% less fuel when running with G® Lubricant compared to standard oil. The tests also showed a 27% reduction in harmful nitrogen oxide (NOx) emissions. Because of the van’s age, a second dose of G® Lubricant was added, bringing the total graphene content to 0.02% by weight in the engine oil.
GMG is based in Brisbane and specializes in clean-technology solutions using graphene, which it produces in-house by decomposing natural gas into its elemental components. This proprietary process yields high-quality, low-contaminant graphene that can be tailored for different applications.
The company’s current focus is on scaling up production and commercializing its products. In addition to G® Lubricant, GMG is marketing graphene-enhanced coatings for heating, ventilation, and air conditioning (HVAC-R) systems, as well as other industrial uses like electronic heat sinks and process plants.
On the energy storage front, GMG is collaborating with the University of Queensland, with support from the Australian government, to develop and commercialize graphene aluminum-ion batteries. The company has also created a graphene additive for lithium-ion batteries aimed at improving their performance.
GMG has identified four primary business objectives: increasing graphene production and enhancing cell manufacturing processes, growing revenue from energy-saving products, developing next-generation battery technologies, and building out supply chain and project execution capabilities.
With the launch of g-lubricant.com, GMG is making a direct play for a share of the global engine lubricant market. The company’s focus on measurable fuel savings and emissions reductions could appeal to both commercial and individual customers looking to cut costs and comply with environmental standards. As GMG continues to test and refine its graphene products, it will be worth watching how the market responds and whether the company can turn lab results into widespread adoption.
