That's not what I've read, but good luck nonetheless. Supposedly, LL-04 is only approved for diesels in Noth America, and gas engines in Europe where they have lower sulphur levels. Not sure if I buy the notion that US gas sulphur levels have dropped that significantly across the board in just the last few years, but I could be wrong.

I have an N55, so I also don't know if the B58's requirements are different. I change my oil every 5-6k so it probably doesn't matter all that much (if at all), but I strictly stick to LL-01 certified oil. Currently on Castrol Euro 0w40 (cheap and available at Walmart). Might give LiquiMoly Special Tec 5w30 a go at my next change; I've been noticing a recent drop in gas mileage, want to see if switching back to a 5w30 makes a difference.
