Don't listen to Ford, get synthetic in to her at 5000km's and change every 5000km's. Ford will like to do the usual 15k interval servicing to keep warranty, they have to retention the turbo and manifold bolts on a regular basis. I have serviced and fixed my cars for the last 10+ years, hate the idea of paying someone to do an oil change - I wouldn't dream getting under mine though.. zero clearance under there to remove/refit oil filter, need a hoist. I get XFT to do my 5k oil/filter change as they do the retentioning every time and ONLY use synthetic. My FPV guys quoted me about $20 Litre for synthetic on oil changes - $140 extra I know what ya mean though, I was shocked to find out that the first 3000km service DIDN'T have an oil change included!
