It does depend on the engine. But since you're posting this in the Regal forums I'm betting the engine you are questioning is either a 2.8L/3.1L/3100 V6 or the 3800 V6 engine

The answer for those engines is pretty much never. They are intended to be maintenance-free and last the life of the engine/vehicle. Only replace it if it is known to be bad/worn and you plan on driving the vehicle for a long time or if you already have the engine removed for other repairs and there is a fair amount of mileage (i.e. >150K miles) on it.

It doesn't need to be replaced for the purpose of preventative maintenance like older engines.
