Was in benin and noticed that most of the commercial buses use gas as an alternative to fuel but can still revert to the normal petrol usage by flipping a switch. Now I noticed that at the special filling station (I only know one in benin) about 95% of those that came to top their gas tanks are commercial bus and taxi vehicles and few private ones.

I made some inquires and was told that the cost is ESTIMATED about N250,000 (INJECTOR ENGINE) and N150,000 (CARBURATOR ENGINE) HOWEVER with a down payment of N20,000 and N5,000 you can have it installed and each time you buy gas they deduct a minute fraction till the payment is done.

I heard that it is vey economical and since commercial operators are heavily into it, I guess it must be because they should know if it is cheaper or not. And they all said " yes it is far cheaper than petrol at little to no extra cost"

So my question is this for those that know about it, Is it advisable for private user? and why the low patronage by private user? or is it the fact that their filling station is not well spread? and is it reliable?
