Product role
What G® LUBRICANT does
Engines waste useful energy through friction, heat and wear. G® LUBRICANT adds GMG graphene to the engine oil, no engine modification, no change to existing maintenance schedules.
Designed for existing diesel and petrol combustion engines through the oil system.
Listed for mineral, semi-synthetic and fully synthetic Group I-IV engine oils.
Covers fuel use, NOx, particulate emissions, friction, wear and engine life.
Commercial additive
Graphene concentrate for existing engine oil systems
Compatible with existing engine oil systems. No engine modification required.
How it works
Graphene acts where engines lose energy
G® LUBRICANT adds GMG graphene into the engine-oil system to reduce friction, support heat transfer and protect metal surfaces under load.
Boundary lubrication
G® LUBRICANT targets the piston ring and cylinder wall, where boundary-layer lubrication influences friction and energy loss.
Heat transfer support
Graphene thermal conductivity supports heat dissipation and engine efficiency.
Wear-scar smoothing
Graphene tribochemical effect helps smooth worn surfaces and reduce friction at the contact point.

Where it fits
Built for operators who track fuel, uptime and emissions together
G® LUBRICANT is most effective when operators can measure fuel use, emissions and wear before and after application.
Fleets
Transport and logistics
For vehicle operators tracking fuel spend, engine hours, service intervals and emissions performance across fleets and duty cycles.
Industrial assets
Diesel and petrol engines
For mechanical assets where friction, wear, fuel use and downtime are already part of maintenance and procurement decisions.
Distributors
Distributors and maintenance partners
For distributors and maintenance partners who need clear product information to support engine-oil recommendations.
Product system
Dosing and compatibility
G® LUBRICANT is available in 50 ml and 500 ml formats with a 1:100 blend ratio.
1:100Recommended blend ratio: add G® LUBRICANT into new engine oil before adding the blended oil into the engine.
500 ml500 ml treats approximately 50 litres of engine oil.
50 ml50 ml treats approximately 5 litres of engine oil. Available in multipacks.
OilsCompatible with Group I-IV mineral, semi-synthetic and fully synthetic oils. Group V synthetic oils excluded.
LimitsNot recommended for combined wet clutch or wet timing belt engines, and not recommended with other oil additive products.

How to apply
A practical fleet sequence: check, dose, run, measure
Check
Confirm engine and oil compatibility
Start with the engine type, oil type, service interval, warranty position and the operating metric you want to track.
Dose
Add at the listed blend ratio
The 1:100 blend ratio gives maintenance teams a clear, repeatable rule across fleet applications.
Run
Use the asset in normal duty cycles
Results are measured against real engine operation, duty cycles, load profile and maintenance history.
Measure
Track fuel, emissions and maintenance signals
Fuel use, NOx where measured, service observations and wear data confirm performance against your baseline.
Buyer questions
Common questions from fleet and maintenance buyers
What is the shelf life of G® LUBRICANT?
Up to five years when stored sealed in the original container, in a cool, dry place away from direct sunlight and extreme temperatures.
Which oil types are listed?
Compatible with mineral, semi-synthetic and fully synthetic Group I-IV engine oils. Group V synthetic oils are excluded.
Where should a buyer avoid using it?
GMG does not recommend the product for combined wet clutch engines or wet timing belt engines. Buyers should check product documentation and warranty conditions before use.
Can it be mixed with other oil additives?
Not recommended for use with other oil additives.
Does it guarantee a fixed fuel saving?
No. GMG presents independent test results, but final outcomes depend on engine condition, oil choice, duty cycle, dosing and measurement method.
Where can a buyer go next?
Visit the G® LUBRICANT store, review product information or contact GMG about fleet use.
