I've read the info on the Royal Purple website and I'm still undecided about using it ... so who can tell me:
If Royal Purple significantly reduces friction, how can it "micro polish" the bearings - doesn't polishing require friction?
If Ford specifies a regular oil for Focus and then specifies certain change intervals for that oil ... and one of the benefits claimed for synthetics is extended performance (Royal Purple claims 12,000 miles - ie: 19,300 km) - why wouldn't you extend the change interval if using synthetic?
Also: where do you buy your Royal Purple and how much?
