What Oil To Use, Full Or Part Synthetic 5W-30 Oil

[joolstdi]

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. "

Thanks for your reply , I have just bought some from Halfrauds they have reduced

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