Graphene Manufacturing Group Ltd (TSX-V:GMG, OTCQX:GMGMF) announced that it has launched a new website to directly market and sell its proprietary graphene-based G Lubricant, a fuel-saving solution for internal combustion engines.
The launch is supported by a new animation video highlighting the product’s ease of use and benefits.
G Lubricant is a graphene liquid concentrate that can be added to any mineral or synthetic engine oil.
When mixed, the graphene content in the final oil blend is around 0.01% by weight. According to GMG, this minimal concentration is safe for all internal combustion engines and has demonstrated measurable performance improvements.
Over the past four years, G Lubricant has undergone controlled testing monitored and verified by The University of Queensland. These tests showed up to 8.4% increases in fuel efficiency in diesel engines.
GMG has reported similar savings from customers using the product in both diesel and gasoline engines over several years of field use.
In recent testing conducted in May 2025, GMG evaluated the product in its company vehicle, a Mercedes Vito diesel van with over 360,000 km of usage, at a third-party dynamometer facility.
This testing resulted in a 13% improvement in fuel efficiency and a 27% reduction in nitrogen oxide emissions after the engine oil was treated with two doses of G Lubricant, totaling 160 ml in 8 litres of oil. The higher dose was used due to the vehicle’s age and condition, the company noted.
Further, G Lubricant is now available in multiple pack sizes through the new website, including a 500 ml bottle and 8-packs of 50 ml bottles, allowing users to dose varying amounts of engine oil.
GMG is also in discussions with potential distributors and original equipment manufacturers to expand global sales.
