The D11 uses patented ceramic technology to break down diesel fuel molecule clusters, reducing viscosity and improving atomization. This means more complete combustion — which translates to better fuel efficiency, smoother acceleration, and lower emissions. The included Air Refining Device optimizes your intake air quality, working together with the fuel enhancer for full-system performance improvement.

Professional installation is strongly recommended. The D11 Fuel Enhancing Device goes inside your diesel tank (avoiding the fuel level sensor float to prevent gauge interference), and the Air Refining Device is fitted to your intake manifold. While the process is non-invasive and doesn't require engine modification, proper placement by a technician ensures optimal performance and longevity.

The D11 is designed for diesel passenger cars and SUVs with tank capacities up to 100 liters. This covers most sedans, crossovers, and mid-size SUVs. If your vehicle has a larger tank (e.g., 200L in light trucks), you'd need our D20/D21 series instead. Not sure? Share your vehicle model and tank size, and we'll confirm the right fit.

Absolutely. Greentech D11 is a non-invasive, maintenance-free device that doesn't alter your engine mechanics or fuel chemistry. It's been tested and certified by TÜV Rheinland (Germany), Taiwan, and Australian DOTARS/Orbital standards. The ceramic material is inert and stable — it simply enhances fuel molecule behavior through far-infrared emission. No risk to your warranty or engine health.

Real-world results vary based on vehicle condition, driving habits, and maintenance history — but our verified fleet tests show fuel efficiency improvements ranging from 5% to 25%. For example, IFFCO UAE's heavy diesel fleet averaged 7.4% savings, while Portugal's Volvo/Mercedes trucks saw 6–8%. Older vehicles or those with poor maintenance may see more dramatic improvements as the D11 compensates for incomplete combustion.

Yes — significantly. India's KSRTC government bus fleet saw emission reductions of 25–85% (HC, CO, NOx), with some BSII vehicles meeting BSIV standards after installation. You'll typically notice less black smoke, reduced odor, and cleaner exhaust. This is because better fuel atomization means more complete combustion and fewer unburned particulates.

Greentech is a B2B product — we don't offer free trials, risk-free pilots, or single-unit consumer sales. Our customers are fleet operators, authorized distributors, and commercial buyers who place initial orders as their validation process. If you're managing a diesel fleet or looking to become a distributor, please share your company details, fleet size, and timeline, and our sales team (Rita) will provide a commercial quotation.

The D11 system has a 10-year lifespan and is completely maintenance-free. Once installed, it works continuously without needing replacement parts, cleaning, or servicing. The ceramic core is designed for long-term stability, making it a one-time investment for a decade of fuel optimization.

We're always open to evaluating partnerships with qualified distributors! However, pricing and territory availability depend on whether we already have an authorized distributor in your region. Please provide: (1) your company name and business type, (2) target countries/regions (list all), (3) estimated first-order volume, and (4) timeline. Our team will check current distribution coverage and get back to you with next steps. We protect existing distributor territories, so duplicate authorization isn't possible.

Pricing is customized based on order volume, application (fleet vs. distributor), and region. We don't publish prices publicly to maintain fair pricing for our commercial partners. To request a quote, please contact us with: your company/organization name, vehicle/fleet details (tank size, quantity), and your location. Rita from our sales team will respond with a tailored proposal.

The D11 is a two-part fuel optimization system for diesel passenger cars and SUVs with up to 100L tank capacity. You get the D11 Fuel Enhancing Device (installed inside the fuel tank) and the Air Refining Device (installed in the intake manifold). Together, they work to improve fuel atomization and combustion efficiency. Both components are maintenance-free with a 10-year lifespan.

The D11 suits most diesel passenger cars and SUVs with fuel tanks up to 100 liters — including brands like Toyota, Ford, Volkswagen, Mercedes, BMW, and others. It works on both common rail and older diesel systems. If you're running a light commercial van or pickup with a larger tank (around 200L), you'd need the D20/D21 instead. For motorcycles or small engines under 20L, we have the D-Ball.

Real-world results vary based on your vehicle's age, condition, and driving habits. Fleet tests show fuel savings typically range from 5–15% for passenger vehicles, with the best results seen in well-maintained cars driven consistently. You'll also notice smoother acceleration, less black smoke, and reduced emissions (HC, CO, NOx). Keep in mind: older engines or aggressive stop-and-go driving may see smaller gains initially, improving over time as carbon deposits clear.

Greentech uses a patented ceramic formula (Molecule Enhance Technology) that emits far-infrared waves. These waves break up clustered diesel molecules, reducing viscosity and enabling finer fuel atomization. The result? More complete combustion, better efficiency, and cleaner exhaust. The Air Refining Device does the same for incoming air, optimizing the fuel-air mix. No engine modifications, no moving parts — just physics.

Absolutely safe. The D11 is a non-invasive device — it doesn't alter your ECU, fuel pump, or injectors. It's been tested and certified by TÜV Rheinland, Taiwan, and deployed in government and commercial fleets worldwide (including KSRTC India and IFFCO UAE). Since it's an external add-on with no engine modification, most manufacturers won't consider it a warranty issue, but we always recommend checking with your dealer if you're concerned.

Greentech is a B2B product designed for fleet operators, authorized distributors, and institutional buyers — we don't offer free trials, risk-free pilots, or client-funded POCs. Your 'proof' comes from the first commercial order. If you're managing a fleet or looking to become a distributor, we're happy to discuss initial order sizing and timelines. Just provide your company details, fleet size, and target rollout schedule, and our team (Rita) will follow up with pricing.

The D11 is sold through commercial orders only. If you're a fleet operator, workshop, or potential distributor, contact us with your company name, location, number of units needed, and timeline. Our business team will provide a quote tailored to your order size. Bulk pricing is available for fleets and distributors — larger orders get better rates. Single-unit retail purchases aren't our focus, but we can point you to authorized partners in select regions.

It's all about tank capacity. The D10 (without Air Refining Device) and D11 (complete system) are for tanks up to 100L — most passenger cars and small SUVs. The D20/D21 handles up to 200L (light trucks, vans). The D50/D51 is for heavy-duty applications around 500L per unit (Class 8 trucks often need 2–3 units for dual tanks). If you're not sure which fits your vehicle, just tell us your tank size and we'll match you to the right model.

The D11 is a complete diesel optimization system for passenger cars and SUVs with up to 100L fuel tanks. You get two components: the D11 Fuel Enhancing Device (installed in your diesel tank) and the Air Refining Device (installed in your intake manifold). Together, they use patented ceramic molecular enhancement technology to break down fuel molecule clusters and optimize air intake — no engine modifications needed. Both devices are maintenance-free with a 10-year lifespan.

We strongly recommend professional installation by a qualified technician. The Fuel Enhancing Device must be positioned in the tank to avoid interfering with your fuel level sensor float (which would throw off your gauge readings). The Air Refining Device requires proper placement in the intake manifold. While the installation is non-invasive and requires no engine modifications, correct positioning is critical for optimal performance.

The D11 works on any diesel passenger vehicle or SUV with a fuel tank up to 100L — sedans, crossovers, SUVs, vans, small pickup trucks. If your vehicle uses diesel and has a tank around 100L or smaller, the D11 is the right fit. For larger tanks (around 200L, like light-duty trucks), you'd need our D20/D21 system instead. For heavy-duty trucks with 500L+ tanks, we offer the D50/D51 series.

Absolutely safe. The D11 is a completely non-invasive device — it doesn't alter your engine, fuel lines, or ECU. It simply sits in your tank and intake system, passively enhancing fuel and air quality through ceramic far-infrared emissions. It's been validated by TÜV Rheinland (Germany), Taiwan, and deployed in government fleets (like India's KSRTC) and commercial operations across the UAE, Portugal, Saudi Arabia, and more. It won't void your manufacturer's warranty because it makes zero mechanical changes to your vehicle.

Real-world results from commercial fleets show fuel efficiency improvements typically between 5–25%, with most falling in the 8–12% range. For example, IFFCO's UAE fleet averaged 7.4% savings, while Volvo/Mercedes fleets in Portugal saw 6–8%. Your actual results depend on your vehicle's age, current condition, maintenance history, and driving style. Older vehicles with more carbon buildup often see the most dramatic improvements. Keep in mind: Greentech enhances what's already there — it can't fix a poorly maintained engine.

Greentech is a B2B product sold through commercial orders only — we don't offer free trials, risk-free pilots, or sample units for testing. The way our fleet and commercial customers "validate" performance is through their initial commercial order. If you're a fleet operator, distributor, or institutional buyer, we're happy to discuss your first order — just provide your company details, fleet size, tank specs, and timeline, and our team (Rita) will follow up with a formal quote.

For commercial orders, fleet pricing, or distributor inquiries, please contact us with: your company name and type (fleet operator, distributor, contractor, etc.), your country/region, the number of vehicles or units you need, tank sizes, and your implementation timeline. Our business team will provide a formal quotation. Pricing varies based on order volume and whether we have existing authorized distributors in your region. We do not disclose pricing in general inquiries — all quotes are handled directly by our sales team to ensure proper qualification and regional clarity.

Yes. Independent testing has shown dramatic emissions reductions: HC, CO, and NOx levels drop significantly, with some tests recording up to 85% reduction in specific pollutants. India's KSRTC government fleet successfully brought older BSII buses up to BSIV emission compliance using our technology. If you're facing tightening diesel regulations or trying to extend the life of older vehicles without costly retrofits, the D11 offers a proven, non-invasive solution that meets international environmental standards (TÜV, , DOTARS/Orbital ADR-79/81, and more).

No maintenance required. Once installed, the D11 system works continuously for approximately 10 years with no servicing, filter changes, or replacements needed. The ceramic technology is passive and doesn't degrade over time. Just install it correctly once, and let it do its job for the next decade.
