What is the exact designation of the Castrol 0w30 engine oil with Volvo release? SLX or EDGE? Didn’t find anything in the SuFu. And: Is this an embarrassing situation when you bring your engine oil yourself for inspection? Before I do that, I will put the WS before the choice: either to calculate a decent price for the engine oil or it will be brought by me. It simply can’t be that I pay EUR 25 per litre and in free trade I get it for a third. Even if you can afford such an XC90, it doesn’t mean that you can be ripped off like that.
