I had a Golf Gti before and I believe the manual states a range of oil weights dependent on region / temperature. As for the current M3/4 it also states both 30W n 40W oils.
40W oils will protect your engine more, if you do more track work n constant hard driving it would be a better choice, hell some track guys use as high as 60W. For city n spirited drives 30W oils would be more efficient. Guys who are topping up constantly tend to think their oils are too thin when actually its due to them not driving hard enough (during run-in period) , the rings aren't seated properly
