No need to keep them appart. Would you really drive around a few miles to get naturegas to get those extra miles? Or would you go for the alternative that is even better for mother earth?
I assume most drives dont care as long as they can fill up the gastubes.
Also in most cases biogas is cheaper then CNG to compensate the lower energy content.
Eon has one good for finding the stations and see what kind of gas the station offers but a general CNG station type is still better then not to offer the fule type in Waze?
