Gud pm! newbie here. Just came for the autogas talk since i'm a newbie there too. My 1999 KIA Pride GTX was converted by NAIADS last March. It has been all that I hoped it would be.
Am particularly impressed by low-end torque, smooth and quiet operation, clean engine and exhaust, clean oil and power.
am also more aware of limitations and imperfections of the "conversion" process being at best a bi-fuel compromise.
I think autogas is ideal green fuel but I think we have to use an "autogas engine" to get the most out of it.
Hope to hear more about your experiences driving on gas!
