Today I looked at an Abarth 500 esseesse with 13,075 miles registered May 2010 that had NO oil changes since new. I lifted the cap and I saw heavy scum and scum inside the top of the 'engine'. Checking the dip stick and after several 'ins and outs' to get a 'marking' found that the oil was thin and appeared to be different colours. After probing the salesman he said that it was topped up last week since none was registering on the dip stick. It was done before going on a 'company night out' about 80 miles down the road with another colleague. Oil on this particular model should be changed every 6K miles as per the revised service schedule. When I looked into the 'scum' problem it may not be a 'show stopper' since it can happen with a car lying in cold wintry conditions and not getting an opportunity to burn off the vapour.
In the US there was a bit of scam with people believing that oil should be changed every 3K miles. The 5K oil service has been bantered around as the ideal mileage at which to give a new car its FIRST oil change.
On
another thread I learned from 'the study' done on Mobil oils that 8K miles was the optimum change. You metioned Shell with the 9K miles - well Mobil guarantee their oils up to 10K miles whilst their 'Extended Performance' (not available in our viscosity range) states 15K miles
IF used with their special filter. On the
severe conditions that can reduce the service interval is Excessive idling - so the majority of cars (possibly 75%) would 'fall' into this category.
So I would still stand by a 5K mile change on the FIRST and there after a 8K mile or 12 month (whichever came sooner) as recommended by JR providing you were not doing the Nurburgring.

The first oil change is often a lot sooner than later ones as during break in rough edges from manufacturing will be worn off and end up in the oil.

Mobil oil has to 'break in' i.e engine wear decreases as the oil ages and that the optimum change is at 8K miles (coincides with the US A500 service schedule).

as recommended" by who? Ford says 5000 miles. Read your manual.
