So what's better, Compressed Gas or Propane ? (CNG or LPG)
I know i europe people were a little apprehensive about CNG. I think you need the tanks to be much stronger and weight much more. I remember my LPG cars had one big tank were CNG cars had a few small but very heavy tanks. CNG will blow much "louder" then LPG too.
Just not sure about the financial part of it.
