[QUOTE="Schwepps, post: 380638, member: 3592"] No Astro, that's not right at all. As I said, there's absolutely no harm in using a LL-04 oil, especially if you're going to change it every 12,000km. Our manuals also say LL-01, LL-01 FE and LL-04 are preferred. But everyone is thinking that LL-04 is a newer standard and a higher no than LL-01, and therefore it must cover and be better than LL-01. I know that's a misconception, and I should say something about it don't you think? LL-04 was put out to meet a EU diesel emission law, and so it has to have lower SAPS. And that means less of some important additives, which results in for example, a lower TBN rating (Total Base Number, an oil's ability to fight acidity, the determinant of the lifespan of an oil) What all this means is that it is not 'better' than LL-01. Does it matter? No. Especially if you're going to change every 12,000km.
