As for the viscosity range I can't see why not in our mild climate, and if we get a drawn out roasting got summer its probably slightly better than 0w/30.

I've experimented over the years and personally find 5w/30 to be the sweet spot on the D5.

Off the top of my head I don't know if A3/B4 is suitable. The Euro4 engines use A5/B5 as thats an extended interval specification but im not so sure about the Euro3 engine, so you might want to just check your handbook for that (I think it would, but check the handbook to be sure).

I wouldn't be concerned about using it in a E3 engine, but keep to the 12k change interval, or less.
