5W30 is the weight specified for your car. 5W20 is the weight specified for ALL Ford gasoline engines 2001 to current, EXCEPT 4.0L SOHC V6 engines.

Ford recommends 5w20 on all 4.6 v-8s ever made (1991- current) but I'd run the 5w30 IMO as that's what it's used to and mainly it helps stay in the gaps a little longer (as a 30w flows a little slower than 20 weight)

Request Motorcraft Full Synthetic from your dealer.
Its designed for high performance and high mileage engines like your GT.
