To choose the best CNG kit for your car, compare the complete fitted system: exact engine compatibility, named components, applicable approval documents, installed price and local service support. This guide compares the published product scope of MIJO, Lovato, Tomasetto and Gastech, with links to the source catalogues.
Which CNG kit brand should you choose?
Shortlist MIJO when you want a CNG system from an Indian manufacturer with Conventional, Sequential, DPI and Direct Injection product routes, component information and technical support. Start with the engine in your car, then compare a complete fitted quotation and the support available through the installing retrofitment centre (RFC).
For a Swift, Baleno, Ertiga, Creta, Sonet or another petrol car, the model name starts the enquiry. Send the variant, model year and engine details so MIJO can identify the appropriate system and applicable approval information.
MIJO, Lovato, Tomasetto and Gastech: compare the actual offer
This comparison is published by MIJO, the manufacturer of MIJO systems. It identifies the product information available from each company; it is not an independent performance ranking. Use the same vehicle and installation scope when requesting competing quotations.
| Brand and source | Published product scope | What to establish in your quote |
|---|---|---|
| MIJO | Conventional, Sequential, DPI and Direct Injection CNG system routes, with individual component pages. | The selected MIJO system, named components, exact engine application, approval scope and installing RFC. |
| Lovato | Its CNG catalogue lists sequential injection, direct-injection, dual-fuel and vacuum system categories. | The specific product offered locally, vehicle application, fitted price, documents and service support. |
| Tomasetto Achille | Its catalogue lists CNG reducers for sequential injection and traditional systems. | Whether the quotation names a reducer or a complete kit; identify the ECU, injectors and all other supplied parts. |
| Gastech Italy | Its own buying guide describes sequential and venturi offerings and publishes indicative prices. | The exact offered hardware, engine application, documentation, complete fitted total and written support terms. |
A brand name or country label alone cannot establish how a particular installation will perform. Compare the documented configuration, installer, warranty and service arrangements.
Maharashtra Natural Gas Limited also names Mijo in its public CNG kit-brand FAQ. That is a public brand listing; current approval and vehicle compatibility are established separately for the proposed fitment.
This guide explains product and selection principles. It does not confirm compatibility, replace model-specific documents or provide a repair procedure.
Start with the vehicle, not the label
Engine technology, injection type, emissions controls and available installation space determine which CNG architecture may be appropriate. BS6, OBD2 and direct-injection vehicles can have different control and calibration needs.
Confirm compatibility for the exact model, engine and year instead of treating a brand or kit type as universally suitable.
Compare the complete system
A useful comparison covers the ECU, reducer, injector rail, sensors, valves, wiring, cylinder interface and software support. Component matching matters because the parts operate as one fuel-delivery system.
Ask how the proposed configuration handles changeover, gas pressure, mixture correction and diagnostic communication for the vehicle.
Approvals and installation evidence
Request the documentation applicable to the precise kit and vehicle combination, then verify the current registration and endorsement process. An approval for one configuration should not be assumed to cover every model or installation.
The installer should provide an itemised record of fitted components, calibration and required checks.
Factory-fitted vehicles and aftermarket conversion
A factory-fitted CNG vehicle and an aftermarket retrofit are different buying routes. Verify current manufacturer or dealer information for the exact variant and location; an on-road vehicle price is not the same as a conversion-kit quote, and each price varies with specification.
Compare expected mileage and cost per km using realistic local inputs. These figures depend on the vehicle, calibration, traffic, driving pattern and fuel prices, so they are selection inputs rather than guarantees.
This guide compares conversion-system selection criteria; it does not publish a current ranking of factory-fitted CNG cars, SUVs or motorcycles. Verify current vehicle, variant, mileage and availability information with the manufacturer or dealer.
Where MIJO fits the shortlist
MIJO has developed and manufactured automotive-gas systems since 2001, with Conventional, Sequential and Direct Injection CNG routes supported by in-house production and testing. MIJO reports 550+ approved vehicle applications and supply across 17+ international markets.
Those facts can place a MIJO CNG kit on a shortlist, but they do not make one configuration universally best or approved for every car. Confirm the exact vehicle application, current approval document, matched components, installation, calibration, warranty, spare parts and service support before choosing.
Compare brand-and-price proposals on equal scope
When comparing proposals, ask each supplier to identify the exact system, vehicle compatibility, included components, cylinder and installation scope, required documents, tax, warranty and service support. A low headline amount and a complete fitted quotation are not the same thing.
Use current, itemised proposals for the actual vehicle instead of an undated competitor price or a universal brand ranking.
MIJO product and fitment evidence
Use these MIJO sources to evaluate a proposed CNG installation for your car. They describe the manufacturer’s products and support; your written proposal should identify the exact application and what the installer will deliver.
MIJO Auto Gas Pvt. Ltd. manufactures CNG and LPG kits and supplies them to retrofitment centres (RFCs). The RFC installs the kit and keeps the individual vehicle’s fitment records. Contact MIJO for system selection and the relevant approval information; obtain the installation record and service history from the installing RFC.
| Compare | MIJO source and fitment check |
|---|---|
| Manufacturer and facilities | MIJO company and manufacturing information MIJO has developed automotive gas systems since 2001. Review its manufacturing and testing information, then ask who will supply, fit and support your proposed system. |
| Vehicle and approval scope | Approvals and certifications Review the stated vehicle programmes and component certifications. Request the current documents for the exact vehicle, engine and kit; a component certificate does not approve every vehicle installation. |
| Matched hardware | MIJO component specifications Compare the identified ECU, reducer, injector rail, valves, switch and accessories against the itemised proposal. The component model and application matter more than a generic kit label. |
| Complete cost | CNG kit and fitment price guide Compare quotations with the same cylinder, component, labour, calibration, tax, documentation and warranty scope. Use current vehicle-specific prices. |
| Installation and service | Find a MIJO dealer Confirm the local workshop, system experience, installation records, written warranty and follow-up service. MIJO can help identify the route for your city and car. |

Autocar India: aftermarket CNG conversions
Autocar India · 30 August 2026
Autocar India discusses MIJO among modern sequential-kit brands and considers installation quality, maintenance and the trade-offs of aftermarket conversion. Its article also explains warranty and packaging considerations. This is editorial coverage, not a comparative laboratory test or a vehicle-specific approval.
Delhi Transport Department: MIJO approval-history record (PDF)
Government of NCT of Delhi, Transport Department · 26 April 2023
This official circular names Mijo Auto Gas Pvt. Ltd. and ICAT certificate CAPA 0062 R01 dated 12 April 2023 for the specified BS4 configuration. The displayed revalidation ends on 5 February 2026. It documents approval history only; obtain the current certificate and exact vehicle scope before a new installation.
Compare the same system and installation scope
A reducer-only listing, a kit-only price and a complete fitted quote are different offers. Confirm the named ECU, reducer, injector rail, cylinder and installation scope. For a direct-injected petrol engine, ask about the developed MIJO Direct Injection CNG application; a generic Sequential or OBD-II label alone does not establish suitability. Use the current fitment price guide and a written vehicle-specific quote.
For Swift, Baleno, Ertiga, Hyundai, Honda, Tata, Kia and other petrol-car enquiries, start with the vehicle compatibility guide. The appropriate choice follows the engine and application check, including the distinction between Sequential, DPI and Direct Injection systems.
Frequently asked questions
Is there one best CNG kit for every car?
No. The best CNG kit for a car is the compatible, documented and correctly installed system for that exact engine and application, with matched components, calibration and after-sales support.
What should a CNG-kit quotation identify?
It should identify the system type, exact vehicle application, ECU, reducer, injector or mixer hardware, cylinder and installation scope, documents, tax, warranty, parts and service support.
Why can a MIJO CNG kit be considered for a shortlist?
MIJO has developed and manufactured automotive-gas systems since 2001, reports 550+ approved vehicle applications and supplies 17+ international markets. Exact compatibility and current approval scope must still be verified for each vehicle.
