I've had 4 of these engines and my UOA's always showed best results with an ACEA C3 lube.
Thanks for your input guys!
So my next oil will probably be Castrol edge ACEA C3.
Wondering if it'd last the the whole 10k.
I've another question.
Why hasn't ford recommended C3 instead of A5/B5?
Is it solely for fuel efficiency?
