Diesel additive test results
GODA is a graphene oxide additive dosed directly into the fuel, with no engine changes. The results below come from a third-party report that you can download.
| Measurement | Result | Notes |
|---|---|---|
| Soot (smoke opacity) | −91.1% | 17.90% → 1.59%, measured by smoke opacity on a FAW diesel engine in ULSD at 8 ppm. |
| NOx | −33% | 325 ppm → 218 ppm. |
| Fuel consumption | up to 12.5% | Longer-term effect; in-treatment figure in the report. |
| Effective dosage | 8 ppm | Eight grams treats one metric ton of diesel. |
| Price, at production scale | under $8/g | Ex-works, at production scale. |
How GODA is used
GODA is a concentrated graphene oxide suspension dosed directly into the fuel. It needs no hardware, no change to fuel handling and no training for the end user.
Allkemie produces it with its patented process, so the chemistry is controlled at the source.
What the test campaign measured
LANDACBIO, at the National Polytechnic Institute of Mexico, ran and reviewed the diesel campaign. The figures in the table above are third-party results.
Soot was measured directly as smoke opacity, and NOx as a direct emissions measurement. The fuel consumption figure is the longer-term effect: improved combustion keeps injectors cleaner over time, so the gain grows with use. The in-treatment figure is lower, and both are in the technical report.
Dose and unit price
The additive is dosed in parts per million, so its cost is a small fraction of the fuel it treats. Dose and price per gram are in the table; the technical report carries the test conditions.
Compatibility
GODA disperses in ULSD and is dosed at the terminal or the tank. At the approved dose it does not require changes to storage or handling.
The 2027 rule
New heavy-duty diesel engines certified from model year 2027 face a 50% particulate reduction and an 83% NOx reduction. Additives with independent verification for both get a hearing.
Questions
Does it require engine modifications?
No. GODA is dosed into the fuel; no hardware, fuel handling or end-user training changes are needed.
Is the data third-party?
Yes. The diesel campaign was run and reviewed by LANDACBIO at the National Polytechnic Institute of Mexico.
Can the report be shared with our fleet engineers?
Yes. The full technical report is downloadable above; the raw dataset is available under request.
