How much money do I save converting my car to CNG or LPG in Nigeria?

Vehicle owners save between 50% and 70% on monthly fuel expenses by converting from petrol to Compressed Natural Gas (CNG) or Liquefied Petroleum Gas (LPG). For a daily commuter or ride-hailing driver, savings typically exceed ₦150,000 to ₦300,000 per month.

Is CNG conversion safe for everyday driving in hot weather?

Yes, CNG is exceptionally safe. The high-pressure cylinders are forged from bullet-resistant steel or carbon-fiber composites and subjected to rigorous hydrostatic crush tests. They feature automatic thermal pressure relief devices (PRD) and excess-flow safety shut-off valves.

Will converting my car to gas damage or wear out the engine?

No. Natural gas has a high octane rating (120-130) and burns far cleaner than petrol, leaving zero carbon residue on valves and spark plugs. This extends engine oil life, keeps spark plugs clean, and prolongs the overall engine lifespan.

Can I switch back to petrol while driving?

Yes. All conversions utilize bi-fuel sequential injection systems. A dashboard micro-switch allows you to switch between petrol and gas seamlessly in real time without stopping or turning off the engine.

Can I convert my petrol generator to run on cooking gas or CNG?

Yes. Testflex Autogas installs dual-fuel conversion kits for residential and commercial generators from 2.5kVA to industrial capacities, allowing them to run on standard LPG cooking gas cylinders or piped CNG.

How long does a vehicle gas conversion take?

A standard vehicle conversion is completed within 24 hours. Vehicles dropped off in the morning are calibrated, safety-tested, and ready for pickup the next day.

Frequently Asked Questions

Everything you need to know about compressed natural gas conversions, safety standards, and operations.

On average, vehicle owners and transport fleets cut monthly fuel spending by 50% to 70%. If you currently spend ₦200,000 monthly on petrol, switching to autogas reduces that cost down to approximately ₦60,000 – ₦80,000, putting over ₦120,000+ back into your pocket every single month.

CNG and LPG cylinders are far stronger than standard petrol tanks. Forged from seamless heavy-duty steel or aerospace-grade carbon fiber composites, they are built to withstand severe collisions, gunfire, and high impact. Each tank is fitted with an automatic thermal Pressure Relief Device (PRD) and emergency solenoid shut-off valves that seal off gas instantaneously in case of any irregularity.

Yes! Testflex Autogas installs precision dual-fuel conversion kits for residential and commercial generators (from 2.5kVA to heavy industrial generators). Running your generator on cooking gas eliminates costly petrol queues, runs quieter, and cuts generator operating costs by more than 55%.

No, it actually protects your engine. Natural gas burns much cleaner than petrol or diesel, leaving virtually zero carbon sludge or abrasive soot inside engine cylinders. This keeps engine oil clean for longer, doubles spark plug lifespan, and extends overall engine durability.

Absolutely. Every vehicle converted by Testflex Autogas features a seamless bi-fuel sequential injection system. A discreet micro-switch on your dashboard allows you to switch between gas and petrol instantly on the move with zero engine stutter or deceleration.

A standard car conversion is completed in under 24 hours. Drop off your vehicle in the morning and pick it up the next day, fully calibrated, road-tested, and certified with a comprehensive parts and craftsmanship warranty.
