Carbon Monoxide is more effective.
I think you will find that nowadays car engines do not spew out the amount of CO required, however I would like confirmation of this as a method as it is far easier than rigging up CO2.
In my case I plan to have all the required stuff ready just in case I decide to need it one day.
