Well, how well do you want it to work.  The real answer is no. We 
generally buy the correct O2 sensor.  Usually a gasoline sensor causes 
the gaseous fueled cars to lean. Like 20 percent. A correction circuit 
can be thrown in, but it is probably easier in the end to get the right 
sender.  That's my experience and opinion.
