Just about to change oil in the car, But there is full synthetic or part synthetic 5w-30 oil to
be had, and they both have the same ford spec on them.
will the full oil give a better protection and also make the engine less rattly or i'm i just wasting
the extra money and should just stay with the semi oil.
the book that came with the car does not specify which oil to put in.
can you shed some light on this.

From surfing around, it seems that the Ford Formula E SAE 5W-30 is semi-synthetic. Blagged from a Focus forum "Halvoline 5w/30 is synthetic according to the tin-Ford Formula E(also made by Texaco)is semi-synthetic and is the recommended Ford oil and is normally cheaper than the price quoted.For 6,000m. changes you don't even need semi-synthetic.10-12,000m. changes should use semi-12,000m.+ changes should use fully synthetic. "

Castrol 5w-30 fully synthetic down to £25.59 for a 4 liter tin.
