Hello to all.I just picked up an 05 crown Vic and looking for some recommendations for this vehicle. I have the service records for the car it has been serviced by the dealer since new so I think its had motor craft 5w20 synblend all its life. However she has 128,889 on the odometer now and I am thinking it's time to go to a high mileage oil. Will be running a motor craft filter on it and 5k oci's. The plan is to get to 250,000 on this motor which I believe is doable. Thanks
