The spec cross references to Genuine Ford oil 97SX M2C200 AB which you can buy from Ford dealer like Lynford Motors in Welshpool.
Otherwise I always recommend Castrol Oil, in this case it is a 75W85 Oil like below. You can use their product guide to find all the oils for your car. It is also in the link below.

As for parts I always try to use genuine Ford where possible, you just know it will fit right to your car, Supercheap is good for oils (usually the cheapest) and nick nacks, but then I use Repco for stuff I cant buy genuine anymore.
