I had my car delivered obn the same day as a friend of mines. Both ST2's.
I ran mine in as per link on the first post, my friend ran his in as per the Ford recommendation.
Both cars where compared at 5000 miles both to drive and on the rolling road.My car felt a lot looser and seem to spool up more quickly, my car on a set route (both cars run bluefin from new) with the mpg reset averaged 28mpg as apposed to my colleauges 26 mpg (same driver). At 10,000miles the mpg stayed the same but the bhp increased slightly, 15000 miles showed an increase in mpg to 29 and 27 respectively.
On the rolling road my car ran 268bhp and the other car 253bhp. Not a huge difference but it was a difference.
We are both keeping logs of fuel consumption and intend to rolling road test every 10,000 miles to see if the margin widens. Both cars are on 4 year contracts, both cars will run over 80,000 miles so we can asses the "running in hard" methods impact on wear rates. by comparing servicing costs and breakdowns at higher mileages.
