Fuel efficiency proven on generators
A mining contractor in South Sumatra wanted to know whether Inneron's biodiesel additive actually improved fuel efficiency. Dump trucks and excavators move across changing terrain, weather, and road conditions all day, so no two runs are comparable. Two site generators, running a stable load, gave a fair test instead.
Generators isolate an additive's fuel efficiency gain from terrain and driver behavior
Dump trucks and excavators are the equipment the contractor cares most about, but they're the worst candidates for a short fuel efficiency trial. Load varies with haul distance and grade, terrain and road firmness change hour to hour, weather changes how hard the engine works, and driver habits add yet another variable on top of that.
Any fuel efficiency number pulled from that kind of day is really a mix of the additive's effect and everything else happening on site. To get a number the contractor could trust, the test needed equipment where only the fuel changed and everything else, load, speed, conditions, stayed the same.
Two site generators fit the bill. Both run a steady, constant load, so any change in kWh per liter of fuel could be pinned on the fuel itself, not a harder shift or a wetter road.
Two generators gained +2.05% to +4.30% kWh/L over one month
Fuel is a mining contractor's largest single cost
A small percentage is a large number
Fuel is usually a mining contractor's biggest single cost, so even a 2 to 4 percent efficiency gain adds up to real savings across a generator fleet.
Savings change what the contractor can bid
A lower fuel cost either improves margin on the current contract, or gives room to bid lower on the next one.
Freed-up budget can fund other work
Fuel savings that aren't needed to protect margin can be spent on other improvements across the site.
Cleaner combustion protects the fuel system
Over time, the same treatment should reduce wear on fuel pumps, injectors, and filters, fewer part replacements on top of the fuel savings.
Inneron's biodiesel additive delivered +2.05% to +4.30% kWh/L gains
Inneron dosed the site's diesel with its biodiesel additive and compared each generator to its own baseline, before and after treatment, under the same steady load. Testing the same units against themselves removed the guesswork that mobile equipment would have added.
Both generators improved. The day unit gained 2.05% more kWh per liter of fuel, and the night unit gained 4.30%, two separate results pointing the same way.
Efficiency gains cut fuel cost and fuel-system wear site-wide
The kWh/L number is the easy part to measure. What the contractor is really after is broader: lower fuel costs, a fuel system that wears more slowly, and a maintenance plan with more room to plan ahead instead of react.

Inneron helps mining and heavy-equipment operators design a controlled fuel additive trial, on the right equipment, so the result reflects the fuel and not the terrain.
