Installation is simple and non-invasive. Open your fuel tank, secure the D10 inside the mesh bag provided, attach it to the stainless steel cable, and lower it into the tank—making sure to avoid the fuel level sensor float. Close the tank and you're done. No engine modification required. The device works passively once submerged in diesel fuel.

The D10 is designed for diesel tanks up to 100 liters. It's ideal for motorcycles, small generators, light vans, and compact diesel equipment. If your tank is larger than 100L, consider the D20 (up to 200L) or D50 (up to 500L) models instead.

No. Once installed, the D10 stays in your tank permanently. It's designed to work continuously for up to 10 years with zero maintenance. Just refuel as normal—the device will keep enhancing your diesel with every fill.

The D10 contains a patented ceramic composite that emits far-infrared energy. It's completely inert—no chemicals are added to your fuel. The ceramics simply break down diesel molecule clusters to improve atomization and combustion. It's safe, non-toxic, and won't interfere with your engine, fuel pump, or injectors.

Yes. Greentech products have been validated by TÜV Rheinland (Germany), Taiwan, Australia's DOTARS/Orbital (ADR-79/81), and deployed in government fleets including India's KSRTC bus fleet and UAE's IFFCO heavy vehicle fleet. Real-world results show fuel efficiency improvements of 5–25% and emission reductions up to 85%, depending on vehicle condition and usage.

The D10 is a B2B solution suited for fleet operators, distributors, equipment rental companies, and organizations running diesel generators or small diesel vehicles. It's ideal if you manage multiple units and want to cut fuel costs and emissions across your operations. Individual users with qualifying equipment are also welcome—just note we don't offer free trials or single-unit ROI calculations.

Fuel savings depend on your equipment's age, condition, maintenance history, and operating habits. Real-world data from commercial deployments shows improvements ranging from 5% to 25%. Older or poorly maintained engines often see the most dramatic gains. We don't provide custom ROI estimates for individual cases—results are validated through your first commercial order.

We don't offer free trials, risk-free pilots, or client-funded proof-of-concept programs. Our validation process is through an initial commercial order. If you're a fleet operator or distributor interested in bulk deployment, contact us with your fleet size, tank specs, and timeline—our team (Rita) will provide a formal quote and discuss next steps.

Yes. We work with authorized distributors, fleet operators, and institutional buyers worldwide. Pricing and terms depend on order volume, target region, and whether an authorized distributor already exists in your area. To explore partnership opportunities, please share your company details, target countries/regions, estimated order size, and deployment timeline—our business team will follow up directly.

The D10 has an operational lifespan of approximately 10 years with zero maintenance. No filter changes, no refills, no servicing required. Just install it once and let it work continuously. After a decade, you can replace it with a new unit to maintain peak fuel enhancement performance.

The D10 is designed for diesel tanks up to 100 liters (approximately 26 gallons). It's ideal for motorcycles, small generators, light trucks, and compact diesel equipment. If your tank is smaller (under 20L), consider our D-Ball model. For larger tanks around 200L, the D20/D21 series is a better fit.

No, the D10 is formulated specifically for diesel fuel. For gasoline engines, use our G-series (G-Ball, G10, G10A, or G11). For LPG or CNG vehicles, we offer a specialized Gas Fuel Saver that requires professional installation into the gas line. Always match the product to your fuel type for optimal performance.

The D10 contains a patented ceramic composite that emits far-infrared energy when in contact with diesel fuel. This energy breaks down molecular clusters in the diesel, reducing viscosity and improving atomization during combustion. The result: finer fuel spray, more complete burn, better mileage, and lower emissions—all without chemicals or additives entering your fuel.

Absolutely. The D10 is a passive, non-invasive device—it doesn't chemically alter your fuel or introduce any additives. The ceramic material is inert and stable, tested to international safety standards (TÜV Rheinland, , ADR-79/81). It's been deployed in government fleets and commercial operations across multiple countries with zero reports of engine damage. You can use it with confidence.

Results vary based on vehicle age, engine condition, maintenance history, and driving habits, but typical fuel efficiency improvements range from 5% to 25%. Newer, well-maintained engines tend to see gains at the lower end of that range, while older or heavily used equipment often shows more dramatic improvement. Many fleet operators also report measurable reductions in smoke and emissions.

The D10 has a functional lifespan of approximately 10 years with zero maintenance required. There are no consumable parts, no refills, and no servicing. Once installed, it works continuously for the life of the product. It's a true fit-and-forget solution.

To explore a partnership, please provide: your company name and type, target country/region, estimated first-order volume, and deployment timeline. Our team will check current distributor coverage in your area and follow up with pricing and terms. Note: we do not offer overlapping territorial rights, and distributor-level pricing is only available in unrepresented regions.

We ship internationally to most countries. Delivery time depends on your location and chosen shipping method—typically 7–21 business days for standard international shipping. For large commercial orders or specific logistics requirements, please contact us directly so we can arrange the best shipping solution for your needs.

The D10 is engineered for diesel tanks up to 100 liters (≈26 gallons). It's ideal for small diesel generators, motorcycles with diesel engines, compact construction equipment, and light utility vehicles. If your tank is larger—around 200L—you'll want the D20/D21 instead. For very small tanks under 20L, check out the D-Ball.

Installation is straightforward: open your fuel tank, secure the D10 unit inside the provided mesh bag, attach the cable/fixings, and position it away from the fuel level sensor float (so your gauge still works correctly). Close the tank and you're done—no engine modifications required. Most fleet technicians or equipment operators handle it themselves, but if you're unsure, a mechanic can do it in minutes.

The D10 is popular with fleet operators running small diesel generators (construction sites, remote telecom stations), farm equipment, marine auxiliary engines, and compact diesel vehicles. It's a B2B product—designed for commercial buyers, distributors, and organizations looking to cut fuel costs and emissions across multiple units.

The D10 has a service life of approximately 10 years and requires zero maintenance—no filters to change, no refills, nothing. Just install it once and let it work. After a decade, you can replace the unit to continue enjoying the benefits.
