is it worth geting company fiting gas for my zen car,is it safe

depends on your daily running. if its going to be more than 60 to 70 kms per day only then is it worth cause a cng kit is going to cost you around rs 35000/- . only if your running is as above then will you be able to recover its cost other wise its not advisable. the old zen has already been phased out .. it is more advisable then to sell it now when you can still get a decent price for it and buy a wagon-r duo(the best small car,better then the zing)it has both ..petrol and cng .

yes it is

yes of course..spl bcos the warranty is nt lapsed...only thing is to get it tuned after evry 15000kms

yes, it is safe please go ahed and get the needful done
