My new DD, a 2004 Crown Vic, requires 5W20 in the 4.6l V-8. Since I can't buy it at Costco, where can I get Mobil1 5W20 buy the case or jug?

Not sure about Mobli-1 but i know Autozone near me sells alot of 5w20 Motorcraft,Castrol,Valvoline and Pennzoil might wanna try a Autozone near you if you have it or Walmart they usually have a big selection.

Could I run 5W30 in place of the 5W20 or is it too thick/heavy for that engine?
