If petrol at roughly ₦1,355 per litre in Lagos is eating your budget, CNG conversion is probably on your mind. The federal government’s Presidential Initiative on Compressed Natural Gas (PiCNG) says the programme has now converted well over 100,000 vehicles. But the latest figures also show real friction: kit prices that range widely, uneven refuelling access, and drivers stranded when a station goes down. This guide breaks down the current numbers, what conversion costs in Nigeria, and whether it makes sense for your car, bus or tricycle.
Where the CNG programme stands in late 2026
The CNG initiative was approved in August 2023 after petrol subsidy removal, with early targets of more than 11,500 new CNG-enabled vehicles and 55,000 conversion kits. According to a State House update reported on 19 September, the programme now counts over 120,000 converted vehicles, more than 400 certified conversion centres and over 90 CNG refuelling stations.
That is a big jump from December 2025, when PiCNG said over 100,000 vehicles were running on CNG, up from about 11,000 in 2023. The presidential mandate is still to reach one million vehicles converted, factory-fitted, manufactured or imported by 2027, and to put CNG infrastructure in all 36 states plus the FCT. In March 2026, President Tinubu directed PiCNG to deploy 100,000 conversion kits nationwide, as petrol prices climbed amid Middle East tensions, and instructed officials to work on lowering kit costs, developing financing and expanding mobile refuelling.
How much does CNG conversion cost in Nigeria?
Reporting by BusinessDay, summarised by EconoTimes in October 2026, puts the cost of a conversion at between ₦650,000 and ₦2.5 million, depending on the vehicle, the kit and the installer. Two examples from that report show how wide the gap can be:
- A mini-shuttle conversion in Ibadan at about ₦700,000.
- A Honda Odyssey conversion that ended at ₦1.68 million on instalments, above an initial quote of ₦1.2 million.
The lesson is simple: get written quotes, ask exactly what is included (cylinder, regulator, injectors, ECU/emulator, labour, certification and a first inspection), and ask whether the price changes if you pay in instalments. Earlier free-conversion drives, such as the pilot centres announced in Lagos in 2024, were limited in scope, so check with PiCNG or your state’s CNG office about any currently running free or subsidised offers rather than assuming one exists.
CNG price vs petrol: what you actually save
Per the same BusinessDay figures, CNG is selling at about ₦380 per standard cubic metre (SCM) for cars and buses and ₦450 per SCM for heavy trucks. Petrol is around ₦1,355 per litre at NNPC stations in Lagos. Note that NNPC’s retail discount ran only to 31 October, and pump prices differ across the country, so treat these as a snapshot, not a fixed rate.
Because CNG is sold per SCM and petrol per litre, a direct comparison is not one-to-one, and the source does not give a litre-equivalent. What drivers report is more useful. One former Uber driver said his fuel spending fell from roughly ₦20,000 to between ₦3,000 and ₦5,000 per journey after converting. The same driver also reported higher spending on spark plugs, ignition coils and engine repairs. Your own savings will depend on mileage, driving style and the quality of the installation.
A simple payback check
- Work out your monthly petrol spend (litres per month × current pump price).
- Estimate your CNG spend for the same distance, using your installer’s stated SCM consumption for your vehicle.
- Subtract to get monthly savings, then add a buffer for extra servicing (plugs, coils, regular gas-system checks).
- Divide your quoted conversion cost by the net monthly saving to see how many months it takes to break even.
High-mileage users such as ride-hailing drivers, dispatch operators, shuttle owners and fleet managers will usually reach break-even far sooner than someone who drives a few hundred kilometres a month.
The biggest problem: refuelling access
Conversion is only half the story. On 24 October, motorists protested at an NNPC Mega Station on Western Bypass in Minna, Niger State, after about three months without CNG, according to TVC News as cited by EconoTimes. Drivers blamed a faulty dispenser component, and the report said there was no alternative CNG facility in the state capital. Most converted vehicles keep their petrol tank, so a dual-fuel setup lets you switch back, but you lose the savings that justified the conversion.
PiCNG’s own figures show the network is still being built. Earlier data for October 2024 to October 2025 listed 72 active stations, with 28 of 63 mother (compression) stations operational and 72 of more than 175 daughter stations operational. Coverage is strongest along gas pipeline routes and in major cities, and patchier elsewhere. Before you convert, check where the nearest working station is and whether it is on your daily route.
Which vehicles suit CNG conversion best?
- Commercial buses and mini-shuttles: high daily mileage, fast payback, and CNG-friendly engines.
- Taxis and ride-hailing cars: savings are significant if you stay within a covered area such as Lagos, Abuja or Kano.
- Tricycles (keke): over 4,600 tricycles were reported running on CNG earlier in the programme, and lower kit costs help operators.
- Private cars with low mileage: payback is slow; weigh the cost carefully.
- Older, poorly maintained engines: fix existing faults first, since a gas conversion will not cure a tired engine.
Safety, certification and maintenance
Only use a certified conversion centre. Poorly fitted cylinders and lines are a safety risk, so ask for proof of certification, cylinder test records and a post-installation inspection. Plan for periodic cylinder inspection and regular checks of the regulator and injectors. If you are shopping for a used car in Nigeria, ask whether it was converted, who did the work and whether the cylinder is still within its test date.
CNG vs electric vehicles for Nigerian drivers
CNG is the cheaper, faster route to lower running costs for most people today because you keep the car you already own. EVs, which PiCNG is also supporting alongside assembly partners and solar charging projects with the Rural Electrification Agency, need a bigger upfront spend and dependable charging. For many commercial operators in 2026, CNG conversion is the more practical step, while EVs remain better suited to those who can charge at home or work.
Key takeaways and FAQ
Key takeaway: conversion can pay off quickly for high-mileage drivers, but only if you have a reliable CNG station on your route and a certified installer. Get quotes in writing and plan for extra maintenance.
How much does CNG conversion cost in Nigeria? Reported costs range from about ₦650,000 to ₦2.5 million depending on vehicle, kit and installer.
What is the CNG price in Nigeria? About ₦380 per SCM for cars and buses and ₦450 per SCM for heavy trucks, per recent reporting. Prices vary by station and location.
Is free CNG conversion available? Free conversion drives have run at selected centres in the past. Confirm with PiCNG or your state before assuming one is open to you.
Can I still use petrol? Most conversions are bi-fuel, so you can switch back to petrol, but check with your installer.
Disclaimer: vehicle prices, fuel prices, import duties and specs change frequently in Nigeria. Always confirm current figures with the dealer, installer or official source before buying or converting.
