Carbon monoxide testing 2.0 and 3.5 Ecoboost vs 3.5 and 3.7 Duratec Which engine generates less CO

Comment below on your best guess on which is better. If you want to have a full discussion on this testing go to MACT Ford Edge on Facebook (link below) This testing is not indicative of any failures or how the systems operate as your results will most likely be different as the cars are aged and used. Maintenance is key to all operations.
