CNG vehicles are gaining ground in Nigeria for their eco-friendly benefits and affordability. However, keeping these vehicles in good condition requires attention to specific maintenance tasks. I’m here to share everything you need to know to keep your CNG car running smoothly, from basic upkeep to addressing common questions about CNG’s efficiency, lifespan, and availability.
TL;DR:
CNG vehicles need unique but straightforward maintenance.
Inspect the fuel system and CNG tanks routinely.
CNG cars can last 10-15 years with good care.
Mileage is around 25-30 km per kg of CNG.
The gas doesn’t expire, but the tanks do—check their lifespan.
Does CNG Need Maintenance?
Sure, it does! Every vehicle does, but the way CNG cars are maintained isn’t quite the same as for petrol or diesel cars. Because CNG burns cleaner, engines don’t wear out as quickly, so some repairs happen less often. But skipping routine maintenance? Bad idea. Here’s a quick breakdown of what you should do:
Fuel System Check-Ups: The filter catches dirt that can clog the system. Clean or replace it every year. Miss this step, and you might regret it when your engine performance drops.
Inspect the Tank: You can’t skip this. Have the CNG tank professionally checked every three years or 36,000 miles (whichever comes first). Damaged or expired tanks are a no-go—they’re dangerous.
General Maintenance Rules: Don’t forget basics like oil changes and replacing air filters. The cleaner combustion of CNG means less gunk in your engine, but regular checks still matter.
Skip these? You’ll pay later in costly repairs or poor vehicle performance.
Is CNG Available in Nigeria?
Yes! CNG is catching on fast here, and there’s a reason for it. It’s cheaper, greener, and safer than traditional fuels. You’ll find CNG filling stations popping up in cities like Lagos, Abuja, and Port Harcourt. The Nigerian government’s push for CNG adoption is paying off, as the infrastructure to support it grows steadily. If you’re worried about accessibility, relax—it’s only getting better.
How Far Can 1kg of CNG Take You?
This one depends. Most CNG vehicles will give you somewhere between 25 to 30 kilometres per kg. Think about it: with rising fuel prices in Nigeria, that’s a significant saving over petrol or diesel. Just plan your routes smartly, and you’ll see your fuel costs drop noticeably.
What’s the Lifespan of a CNG Vehicle?
This is where CNG cars shine. If treated well, they’ll serve you for 10 to 15 years, sometimes longer. Because CNG is clean-burning, it doesn’t gum up your engine like traditional fuels. Of course, it’s not magic—if you drive like a maniac or skip maintenance, your car won’t last.
Regularly change out worn parts, keep your vehicle tuned up, and pay attention to the manufacturer’s recommendations. It’s simple advice, but it works.
Can CNG Expire?
The gas itself? Nope. But the cylinder holding it? Yes. A typical CNG tank lasts 15 to 20 years. These tanks aren’t designed to be recertified after expiration. Once a tank reaches the end of its usable life, replace it immediately—it’s not negotiable.
Always keep an eye on the expiration date stamped on your tank. If you’re nearing the end of its lifespan, don’t wait for a problem—swap it out early.
Final Thoughts
Maintaining a CNG vehicle doesn’t have to be complicated. With routine care and attention to a few key details, Nigerian drivers can enjoy cost savings, eco-friendliness, and long-term reliability from their CNG vehicles.
Stay proactive, plan for regular inspections, and always replace parts before they fail. With a bit of effort, your CNG car will run clean and smooth for years.
