Brisbane, Queensland, Australia--(ACN Newswire via SeaPRwire.com - May 27, 2025) - Graphene Manufacturing Group Ltd. (TSXV: GMG) (OTCQX: GMGMF) ("GMG" or the "Company") is pleased to announce the following internal GMG run engine test results when G® Lubricant was added to a Caterpillar 22 kVA diesel engine run at an 80% Load. Test results show a 10% increase in energy efficiency (kwh/litres), and also a 33% reduction in harmful diesel engine exhaust particulate matter emissions, when three doses of G® Lubricant, with a maximum graphene dosage of 0.03%, was added to the standard diesel engine oil.It is noted that the test engine was not operating optimally before G® Lubricant was added - the engine was overheating at long runs of sustained high loads. As a result, after the initial dose of G® Lubricant was added, an additional two dosages of G® Lubricant were used to hopefully bring the engine into a more stable operating regime, an outcome that was generally achieved.Figure 1To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/253490_gmg_image.jpgBuy Now at: www.G-Lubricant.com Figure 2 and 3 show the table and graph distribution of engine efficiency of the various dosages of G® Lubricant versus the baseline.Baseline Diesel Engine OilEngine Efficiency (kwh/litres)G® Lubricant (0.01%)Engine Efficiency (kwh/litres)G® Lubricant (0.02%)Engine Efficiency (kwh/litres)G® Lubricant (0.03%)Engine Efficiency (kwh/litres)3.043.36 (10% increase)3.35 (10% increase)3.36 (10% increase)Figure 2: Engine Efficiency Performance Increase from G® LubricantFigure 3: % Distribution of Fuel Efficiency Relative to BaselineTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/253490_d626526a342c2ac9_005full.jpgFigures 4 and 5 show the table and graph distribution of diesel engine particulate matter emissions of the various dosages of G® Lubricant versus the baseline.Baseline Diesel Engine OilParticulate Matter (ppm)G® Lubricant (0.01%)Particulate Matter(ppm)G® Lubricant (0.02%)Particulate Matter (ppm)G® Lubricant (0.03%)Particulate Matter (ppm)20.9715.56 (26% reduction)14.55 (31% reduction)13.97 (33% reduction)Figure 4: Engine Emission Particulate Matter Reduction from G® LubricantFigure 5: % Distribution of Particulate Matter in Emissions Relative to BaselineTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/253490_d626526a342c2ac9_006full.jpgFigure 6 shows the exhaust emissions of the diesel engine at various dosages of G® Lubricant, versus the baseline which shows similar levels as the baseline test runs.

This oil change was carried out by a professional engine maintenance service company.The engine was run at 80% load and the baseline and G® Lubricant data set used for the analytics is when the maximum ambient temperature for the day was less than 33 degrees Celsius and relative humidity was between 50% and 80% with no rain. Fuel consumption for diesel engines changes when operating in rain or very high humidity or temperatures, so the fuel consumption data baseline and G® Lubricant engine oil additive performance testing were excluded for these times.Only steady state data was used and so any variance or anomalous data seen in either baseline or G® Lubricant datasets were removed from the analytics. Data sets were grouped into minute blocks.Once the baseline fuel tests were completed, G® Lubricant with approximately 1:100 concentration was mixed at approximately 1% ratio by weight into the existing engine oil. This was done another 2 times. The end ratio of GMG's Graphene to the diesel engine oil was approximately 3:10,000 by weight.GMG's Managing Director and CEO, Craig Nicol, commented: "G® Lubricant is not only increasing fuel efficiency it is also reducing particulate matter - which is amazing to see - we will need to do more tests to see what the long-term performance is for this."GMG is continuing to conduct more tests to determine the total performance regime of the G® Lubricant. These performance tests will be announced as the information becomes available.GMG's Chairman and Director, Jack Perkowski, commented: "Fantastic news - G® Lubricant testing data are exciting - well done to the team - showing great promise as a way to reduce fuel costs and emissions across the multi-trillion dollar liquid fuels industry."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:Produce Graphene and improve/scale cell production processesBuild Revenue from Energy Savings ProductsDevelop Next-Generation BatteryDevelop Supply Chain, Partners & Project Execution CapabilityFor further information please contact:Craig Nicol, Chief Executive Officer & Managing Director of the Company at craig.nicol@graphenemg.com, +61 415 445 223Leo Karabelas at Focus Communications Investor Relations, leo@fcir.ca, +1 647 689 6041Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accept responsibility for the adequacy or accuracy of this news release.Cautionary Note Regarding Forward-Looking Statements This news release includes certain statements and information that may constitute forward-looking information within the meaning of applicable Canadian securities laws.
