The Acea A5/B5 is OK and almost the same as A3/B4. Although it's a fraction better for petrol jobs due to the use of different types of detergent additives (More Magnesium than Calcium). Mg lasts slightly longer than Ca based detergents.
Castrol Edge 0w30 the Volvo approved oil is a high end 30 grade and in SAE terms almost a 40 grade. That viscosity was chosed for fuel economy, not minimum engine wear. Older or higher time (More than 100K miles) engines like thicker oils in summer, so I use an 0 or 5w40 major brand full synthetic.
Shell Ultra 5w40 (They do make a A5/B5 but it's a more expensive 0w40) is probably the cheapest GTL (Gas To Liquids) full synthetic if you buy from a major Fleabay dealer like Opie Oils or Oil Drop.
