5w-30 is correct.
if you would like the oil that ford use get semi-synthetic 5w-30 formula-E
you can buy it from the ford parts desk and its no more expensive then good oil from halfords (£25.99 for 5 litres)
however any 5W-30 oil that conforms to ford specification WSS-M2C913-B will be fine
this has already been discussed in detail, see here
