I searched for more oils, I found the GM Opel Dexos 2 5W-30, that has LL04 approval.
It's the cheapest I could find, 5L for 20$. Is this a good option?
Are you going for price or appropriate oil?
I'd rather go for appropriate oil. I want a good oil, instead of paying for brand name.
As I said, I use LM toptec 4200 5W30, but it's very expensive 50$/5L. I read in some forums that is not worthed for it's properties, that has a lot of marketing.
Here, Castrol is also on that price range, but I'm sure that I can get a good oil without paying so much. Or am I being too unrealistic?
