Are all oil brands of 5W/30 equal?

My car maker advises fully synthetic 5W/30 engine oil. Are all oil brands of 5W/30 equal?
There are many brands of oil on the market, some well known (Castrol/Mobil/Shell) and there are others such as Halfords that will also meet the specification that your manufacturer recommends. However, some car manufacturers do specify the make of the oil but although you should keep with the actual specification( i.e 5W/30 ) the actual choice of the make of oil is down to you. Your requirement is 5W/30 Fully synthetic with an ACEA C2 grading.

On a personal choice and with a relatively new car I would stay with the specification and would also purchase one of the better-known oil manufacturers
