Simply drop the D20 device into your diesel tank through the filler neck — no tools, no engine modifications required. Make sure to position it away from the fuel level sensor float to avoid interfering with your fuel gauge. The ceramic unit will sink to the bottom and start working immediately. Installation typically takes under 5 minutes. For fleet deployments or marine vessels, we recommend having a technician handle the install to ensure proper placement.

The D20 is engineered for mid-size diesel tanks ranging from 101 to 200 liters (approximately 27–53 gallons). It's ideal for SUVs, pickup trucks, light commercial vehicles, mid-size boats, and small to medium construction equipment. If your tank is smaller (under 100L), consider the D10/D11. For larger tanks (around 500L), you'll need the D50/D51 — and heavy-duty Class 8 trucks with dual tanks often require 2–3 units.

Greentech's patented Molecule Enhance Technology uses a special ceramic formula that emits far-infrared waves. These waves break down the molecular clusters in diesel fuel, reducing viscosity and enabling finer atomization during combustion. The result: more complete burning, less wasted fuel, lower emissions (HC, CO, NOx), and measurably better mileage. Real-world tests — including UAE's IFFCO fleet and India's KSRTC buses — have documented 5–25% fuel savings and up to 85% emission reductions, depending on vehicle condition and usage.

Absolutely. The D20 is a non-invasive, passive device — it doesn't alter your engine, inject chemicals, or interfere with any mechanical parts. It's been certified by TÜV Rheinland (Germany), Taiwan, Australia's DOTARS/Orbital (ADR-79/81), and tested by fleets worldwide. The ceramic material is inert, corrosion-resistant, and designed to last 10+ years with zero maintenance. It won't void your manufacturer's warranty because it requires no engine modification.

The D20 is a B2B product designed for fleet operators, authorized distributors, logistics companies, construction firms, and mid-size marine operators — anyone running diesel vehicles or equipment with 101–200L tanks and looking to cut fuel costs and emissions at scale. It's not a retail consumer product. If you operate a fleet of light trucks, delivery vans, or work boats, and you're tired of rising diesel prices eating into your margins, the D20 is built for you.

No. Greentech does not provide free trials, risk-free pilots, or client-funded POCs. Our product has already been proven through commercial deployments and government fleet testing across India, UAE, Portugal, Saudi Arabia, Qatar, Germany, Vietnam, and more. Your first order is a commercial order — not a test. To verify performance, we recommend starting with a small initial batch for your fleet, then scaling up based on results.

Pricing is customized based on order volume, fleet size, and deployment timeline. We do not publish prices publicly. To request a quote, please provide: your company name and type (fleet operator, distributor, contractor, etc.), country/region, number of units needed, and your target implementation schedule. Our sales team (Rita) will respond with a tailored commercial proposal. For distributors interested in regional exclusivity, we'll first verify whether your target territory already has an authorized partner.

Typical results range from 5–25% fuel savings and 25–85% emission reductions (HC, CO, NOx), depending on vehicle age, maintenance history, and driving conditions. Older, poorly maintained engines often see the most dramatic improvements. The D20 has a functional lifespan of approximately 10 years and requires zero maintenance — no filters to change, no parts to replace. Simply install it once and let it work passively for the life of the vehicle or until you upgrade your fleet.

Yes — but distributor pricing and territory rights depend on whether your target region already has an authorized Greentech partner. If you're interested in distribution, please provide a complete list of the countries/regions you want to cover. Our team will check current distributor status for each territory and get back to you. We protect existing partners by not offering overlapping regional rights or undercutting their pricing. If your region is open, we're happy to discuss terms for an initial commercial order and potential exclusivity.

No maintenance required. The patented ceramic core has a design life of approximately 10 years under normal operating conditions. There are no filters to change, no electronics to service, and no consumables to replace — just drop it in and forget it.

The D20 uses a proprietary ceramic formula that emits far-infrared radiation to break down diesel molecule clusters. The material is chemically inert, non-toxic, and will not dissolve or contaminate your fuel. It's been tested by TÜV Rheinland, Taiwan, and multiple international labs — completely safe for pumps, injectors, and all fuel-system components.

Typical results range from 5–15% fuel savings for mid-size diesel vehicles, depending on vehicle age, engine condition, load patterns, and driving habits. Real-world fleet tests (UAE IFFCO, Portugal Volvo/Mercedes fleets) recorded 6–8% average savings. Older engines or stop-and-go routes often see higher gains. Results are not guaranteed and vary by application.

No. The D20 is formulated specifically for diesel fuel. For gasoline engines, use the G10/G11 or G10A series. For LPG/CNG vehicles, we offer a separate Gas Fuel Saver that installs inline in the gas supply pipe. Always match the product to your fuel type for optimal performance.

No. Greentech is a B2B product line, and we do not provide free trials, risk-free pilots, or client-funded POCs. Validation happens through your first commercial order. If you're a fleet operator or distributor, provide your fleet size, tank specs, and deployment timeline — our sales team (Rita) will prepare a custom quote and discuss deployment terms.

The D20 (and Greentech's diesel range) is supported by independent testing from TÜV Rheinland (Germany), Taiwan, Australia DOTARS/Orbital ADR-79/81, and field deployments including India's KSRTC government bus fleet (25–85% emission reduction), UAE IFFCO heavy fleet (7.4% avg. fuel savings), and Portugal's Volvo/Mercedes truck fleets (6–8% savings). We do not reference outdated CEE reports. All cited results are from commercial or government fleet deployments, not lab-only tests.

The D20 package includes one fuel-tank ceramic enhancer unit only — no air-intake device is included. If you want to further optimize combustion, you can purchase a separate air purifier for your intake manifold. However, many fleet operators start with the fuel device alone and see measurable results before adding the air unit.

Distributor-level pricing is available only in regions where we do not yet have an authorized distributor. If you're interested in representing Greentech in your country or region, please provide: (1) your complete target territory list (all countries/regions), (2) your company name and type (importer/distributor/fleet operator), (3) estimated first-order volume, and (4) deployment timeline. Our team will check existing distributor coverage and reply with terms where territory is available. We cannot duplicate authorization in regions already served, to protect existing partners.

Most fleet managers or vehicle owners can install it — simply drop it into the tank. However, **we recommend having a technician or mechanic handle the installation** if you're unsure about your tank's internal layout (especially the location of the float sensor). Proper positioning ensures accurate fuel readings and optimal performance over the device's 10-year lifespan.

The D20 is engineered for **diesel-powered vehicles and equipment with 101–200L (roughly 27–53 gallon) fuel tanks** — think SUVs, pickups, light-duty trucks (e.g., Ford F-250/350, Ram 2500), delivery vans, small forklifts, mid-size agricultural machinery, and mid-size boats. If your tank is smaller (≤100L), choose the D10/D11; larger tanks (~500L or Class 8 trucks) need the D50/D51.

Greentech's patented **Molecule Enhance Technology (MET)** uses a specially formulated ceramic core that emits far-infrared waves. These waves break up diesel molecule clusters, reducing viscosity and enabling much finer atomization when the fuel is injected into the combustion chamber. The result: **more complete combustion, less wasted fuel, and significantly lower emissions** (HC, CO, NOₓ). The ceramic is inert, non-toxic, and maintenance-free — it simply sits in your tank doing its work 24/7.

Absolutely safe. The D20's ceramic core is chemically inert and **does not dissolve, shed particles, or react with diesel fuel**. It's been certified by TÜV Rheinland, Taiwan, and deployed in thousands of commercial vehicles (including government fleets in India and UAE) with zero reports of engine damage or fuel contamination. The device works purely through physical energy emission — no additives, no chemicals.

Real-world fleet data shows **5–25% fuel savings** and **up to 85% emission reductions** (depending on vehicle age, condition, and driving habits). For example, UAE's IFFCO fleet averaged 7.4% monthly fuel savings across six 550L-tank trucks; India's KSRTC bus fleet cut emissions by 25–85% and met stricter standards without engine overhauls. **Your mileage will vary** — older, poorly maintained vehicles often see bigger gains because combustion was less efficient to start with.

The D20 has a **10-year functional lifespan** and requires **zero maintenance** — no cleaning, no filter changes, no re-activation. Just install it once and let it work. After a decade, the ceramic's far-infrared emission gradually diminishes; at that point, you can replace the unit to maintain peak performance.

Greentech is a **B2B commercial product** — we do not offer free trials, pilots, or money-back guarantees. Your first order is a commercial deployment. Think of it as any other fleet component purchase: you evaluate the proven track record (KSRTC India, UAE IFFCO, TÜV certification, etc.) and make a business decision. If you're a fleet operator or distributor, **provide your fleet size, tank specs, and timeline**, and our sales team (Rita) will prepare a custom quote with volume pricing.

Pricing is **not published online** because it varies by order volume, region, and customer type (end-user fleet vs. authorized distributor). To receive a quote, **email or contact us with**: (1) your company name and type (fleet operator, distributor, contractor), (2) number of units needed, (3) vehicle/tank specs, and (4) deployment timeline. Our team (Rita) will respond with a tailored B2B quote. **Volume discounts and distributor-level pricing are available** — but distributor pricing only applies to regions where we don't yet have an authorized partner.

We're always open to qualified distribution partners — **but first we need to verify whether your target region already has an authorized distributor** (we protect existing partners and cannot offer the same terms in their territories). **Please provide**: (1) complete list of countries/regions you want to cover, (2) your company background, and (3) estimated first-order volume and timeline. Our sales team will check each territory and get back to you. If the region is open, we'll discuss distributor pricing and terms; if it's already assigned, we can explore adjacent markets or alternative partnership models.
