Find CNG before you need it.
A guide for CNG drivers: how Avvgo finds CNG stations near you and along your route, how your own fill-ups make it smarter, and how it learns what your car really gets per kilo.
Three places to look for CNG, plus your own fills.
CNG pumps are easy to miss. Avvgo looks in several places and shows you where each answer came from:
- Google: fuel stations near you or along your route that are listed with CNG.
- OpenStreetMap: stations that volunteers have marked as selling CNG, kept on your phone so they still show with a weak signal.
- A second opinion on whether a station sells CNG, where one is available.
- Your own fill-ups: the strongest evidence of all.
Your fill-ups confirm the stations.
Every time you log a CNG fill, Avvgo remembers the station. Stations where you’ve filled rise to the top of the list, and recent fills count for more than old ones.
Found a pump with no CNG? Mark it, and it drops down your list. Nothing is copied from company station locators; the list is built from open data, map listings and your own driving.
Plan refuels on long routes.
Avvgo keeps a running estimate of how much CNG is left, from your last fill and the distance you’ve driven since. When you’re down to about 50 km of range, it tells you once and shows the stations ahead. At about 20 km it reminds you again.
Planning a longer drive? Ask the assistant where to fill on the way, and what the CNG will cost.
Know your real km/kg.
Brochure figures are measured in a lab. Your number depends on your roads, your load and your right foot. Mark full tanks and Avvgo works it out from one full fill to the next, and keeps refining it.
- CNG in km/kg, petrol and diesel in km/L, per car.
- Your real figure drives the range estimate and every trip cost.
CNG questions
How do I find a CNG station near me?
Open the stations view in Avvgo. It lists CNG stations around you from Google and OpenStreetMap, with the ones where you have filled CNG before at the top. During a trip, it shows the stations ahead of you on your route.
Are the CNG stations always right?
Not always. Listings can be out of date, and no app knows if a pump is closed, out of gas or has a long queue right now. That is why Avvgo puts the stations you have actually filled at first, and lets you mark a station that turned out to have no CNG.
Does Avvgo show CNG prices?
It uses the rates you enter at each fill-up. Trip costs use your most recent rate, so they match what you actually pay.
How does Avvgo know my CNG mileage?
Mark a fill-up as a full tank. From one full fill to the next, Avvgo divides the distance you drove by the kilos you filled. It keeps refining this, so it learns your car’s real km/kg rather than the brochure figure.
What about bi-fuel cars that switch to petrol?
Avvgo keeps CNG in kilos and petrol in litres for the same car. When the CNG runs out and the car switches over, the rest of the distance is counted on petrol.
Is Avvgo only for CNG cars?
No. It works for petrol and diesel cars too. The CNG station finder is there because CNG pumps are the hard ones to find on a highway.
