Here in the US, the Accord Euro is called the Acura TSX. Unlike their US Accord recommendation for 5W-20, they recommend 5w30 for the high output version of the 2.4L in the Euro Accord. However, if you look for a recommendation in the Castrol UK website, you will find Castrol RS 0W-40. This oil is PAO and not hydrocracked group III according to the German website.
