The title says dynamic cylinder deactivation but is it really dynamic .
Can it change which group of cylinders it wants to shutdown .
This is main reason I am not a fan of cylinder deactivation . those cylinders that get shutdown at part throttle end up with plugs missing after a while and possible oil issues as while the plugs never stop sparking there no combustion to clean them off .
Many manufactures are using these systems, they don't give big boost in mpg but maybe few mpg with mid size V6 . hardly any improvement in city driving as most systems would be in full mode most times .
