NanoEFX for mining & quarrying
NanoEFX is a passive, water-based air-filter treatment for combustion engines with a treatable air filter or intake medium. Based on results observed across multiple documented combustion-engine applications, we have reason to expect an effect in suitable mining engines. We have not yet run a mining-sector trial, however, and the closest loader evidence in our records was negative — so the magnitude of any effect should be measured under the mine's own operating conditions.

A coating on the air filter — not a fuel additive or a remap
NanoEFX is sprayed onto the engine's existing air filter, where it dries into a thin, breathable nano-coating. As the engine draws air through that treated surface, the coating conditions the intake air before combustion — supporting a cleaner, more complete and more efficient burn. For a mine fleet, that means the same treatment works across every engine that breathes through a treatable filter.
What it is
- A passive nanostructured intake-air treatment
- Applied to the air filter you already service
- Water-based — dries to a thin, breathable coating
- Works before combustion, at the intake-air stage
What it isn't
- A fuel additive or oil additive
- An ECU remap or tuning
- A mechanical retrofit or powered device
- Anything that changes how you operate
Three pressures every mine operator already feels
These are the forces that make intake-air efficiency worth acting on — independent of any single engine or duty cycle.
Diesel is one of a mine’s biggest costs
Haul fleets and mobile plant burn enormous volumes of diesel, so fuel is a dominant operating cost. Because the effect repeats over huge run-hours, even a small percentage gain is a large absolute saving.
Decarbonisation pressure in mining
Miners face investor and stakeholder pressure to cut Scope 1 diesel emissions. A more complete burn means less wasted fuel and lower emissions, without replacing the engine.
Remote fuel logistics
Fuel is expensive and complex to deliver to remote sites. Using less has outsized value where every litre has already cost a great deal to get there.

No trial data from this sector
We have not run a trial in mining. Rather than borrow a number from another sector, here is exactly what we do and do not hold.
The nearest evidence we hold
The closest equipment in our records is heavy haulage and loaders. Two 10 tonne tippers improved by around 6% in fuel efficiency measured in km/L, and both loaders we have measured consumed more fuel after treatment. Loaders and haul trucks share the high-load, low-speed, heavily variable duty that mining runs on, so that negative result is the more relevant of the two — and it is a caution, not a selling point.
What a trial here would have to look like
A mining trial we would trust needs untreated sister machines working the same benches over the same weeks, fuel drawn from the same bowser, and payload logged per cycle. Without payload data a haul-truck comparison measures the pit plan, not the engine.

From a haul truck to a site compressor
A mine is rarely one machine. NanoEFX applies to mining engines that breathe through a treatable air filter, and it conditions the intake air regardless of the fuel burned.

Fuels
No workshop, no downtime, no new hardware
NanoEFX is applied by your own team, onto the air filter they already remove at service. It rides on the maintenance you do anyway rather than adding a new one.
What a cleaner burn means for a mine fleet
NanoEFX doesn't add energy or oxygen and doesn't modify your engine — it helps the engine waste less of the energy already in the fuel. NOx response is engine- and control-system dependent.
Common questions from operators
Does NanoEFX work on mining haul trucks and heavy diesel plant?
Will it change the engine or need a remap?
How often does it need reapplying on a haul fleet?
Does it help cut diesel emissions and support ESG targets?
Does it affect a DPF, SCR, EGR or AdBlue system?
Don't take the claim — measure it
The most honest evidence is your own baseline. In a NanoEFX pilot you run a controlled trial on your own engines, measured against your own fuel data — and you only pay if it proves savings.
