pretty sure it just around 4.2LTR but imo opinion oil is like a woman get one that is best you can afford. or unless you like trackie wearing whores then buy asda smart price oil.
in all serious i use fuchs titan pro double ester 5-40 oil. had it in cars for years. never killed an engine yet last car i drove like i stole it, took it on track etc and survived no problem. (wasnt a golf ill add) get the best you can afford imo
