Having said that, I stick with an LL01 rated oil (on my Euro 3 M57TÜ) - Castrol Edge 5w/40 - as I don't want to pay for features in an oil that aren't required by my engine.
Different oils/brands may be tested against one spec but not others, so you can see a varied mix of specs on similar oils.
And BMW or Porsche don't rate oils - they release a spec. (requirements to be met) and oil manufactors test against these standards. Or not. An oil that meets Porsche A40 may well also pass LL01 but may not have actually been tested against that spec. |
Dog and a bone, still coming back to this, even though i reckon you answered, soooo I kept an empty container of mobil 1 0/40w (from 2009) (dont ask) and spec / say meets bmw longlife 01, mercedes benz 229.3,porsche a40 etc and some others I cant recall, as well as having the acea A3/B4 rating ...reviewing some other brands of on the shelf oils recently I see they all have this compliance/approval by all the aforementioned apart from the bmw LL01 ...thats what sort of bugged me.
