GMG Launches G-Lubricant.com: A Transformative Graphene Energy Saving Solution for the Multi Trillion Dollar Global Liquid Fuel Industry

Rhea-AI Summary

Graphene Manufacturing Group (GMGMF) has launched G-Lubricant.com, a website for direct sales of its innovative graphene liquid concentrate for engine performance enhancement. The G® Lubricant, which contains a graphene-to-oil ratio of 1:10,000, has demonstrated significant performance improvements in internal combustion engines. Testing conducted over four years and verified by The University of Queensland showed fuel efficiency increases of up to 8.4% in diesel engines. Recent tests on a Mercedes Vito van revealed even more impressive results, with 13% fuel savings and 27% reduction in NOx emissions at 2500 rpm and 100 km/hr. The product is available in various pack sizes, including 500ml and 8x50ml options, and GMG is currently in discussions with potential global distributors and original equipment manufacturers.

Unleashing the Power of Graphene

G® Lubricant is a graphene liquid concentrate that can be added to any mineral or synthetic oil used in an internal combustion engine. The amount of graphene in the final lubricant once G® Lubricant is added in is only ~ 1:10,000, with the balance of the concentrate consisting of lubricating base oil. As a result, G® Lubricant can be used safely in any internal combustion engine. Over the past four years, GMG has conducted environmentally controlled testing of G® Lubricant in internal combustion engines monitored and verified by The University of Queensland. In those tests, G® Lubricant has been shown to increase fuel efficiency by up to 8.4% in those diesel engines tested. GMG's test results have been corroborated by similar savings realized by customers over a number of years of field testing in diesel and gasoline/petrol engines.

G® Lubricant is currently sold by GMG in different pack sizes on the direct marketing website including a 500 ml litre pack and 8 x 50 ml packs, which can be used to dose 50 litres of engine oil and 8 x 5 liters of engine oil, respectively, to provide improved engine performance. GMG intends to direct market the product to its targeted markets through various pack sizes for direct and bulk use to create awareness of the product and its benefits.

In addition, the Company is discussing global sales with potential distributors in different geographic areas and different original equipment manufacturers.

Further G® Lubricant Performance Tests

GMG carried out further G® Lubricant testing in mid May 2025 - this time in its Company van which was recently professionally serviced - a Mercedes Vito on a third party dyno testing facility (Figure 4) with diesel engine exhaust emissions testing as well (Figure 5).

The performance testing showed demonstrated that the diesel engine van running at approximately 2500 rpm, 100 km/hr with approximately 400 Nm torque, the G® Lubricant provided approximately 13% of fuel savings (Figure 2) and a reduction of harmful NOx exhaust emissions of 27% (Figure 3) compared to testing under similar conditions without the use of any G® Lubricant.

A second dose of G® Lubricant was added to achieve these results due to the age and condition of the engine which has over 360,000 km of use - hence the total amount of graphene per engine oil was 0.02% (2 in 10,000) by weight - there was a total of 160 ml (2 x 80 ml) of G Lubricant added to the 8 litres of engine oil.

About GMG:

GMG is an Australian based clean-technology company which develops, makes and sells energy saving and energy storage solutions, enabled by graphene manufactured via in house production process. GMG uses its own proprietary production process to decompose natural gas (i.e. methane) into its natural elements, carbon (as graphene), hydrogen and some residual hydrocarbon gases. This process produces high quality, low cost, scalable, 'tuneable' and low/no contaminant graphene suitable for use in clean-technology and other applications.

The Company's present focus is to de-risk and develop commercial scale-up capabilities, and secure market applications. In the energy savings segment, GMG has initially focused on graphene enhanced heating, ventilation and air conditioning ("HVAC-R") coating (or energy-saving coating) which is now being marketed into other applications including electronic heat sinks, industrial process plants and data centres. Another product GMG has developed is the graphene lubricant additive focused on saving liquid fuels initially for diesel engines.

In the energy storage segment, GMG and the University of Queensland are working collaboratively with financial support from the Australian Government to progress R&D and commercialization of graphene aluminium-ion batteries ("G+AI Batteries"). GMG has also developed a graphene additive slurry that is aimed to improve the performance of lithium-ion batteries.

GMG's 4 critical business objectives are:

1. Produce Graphene and improve/scale cell production processes
2. Build Revenue from Energy Savings Products
3. Develop Next-Generation Battery
4. Develop Supply Chain, Partners & Project Execution Capability
