Friends,The problem with most so called specialist or pro or what not mechanics, do they know the fact that ultra-modern alloy-made engines needs very specially designated oil for them? I've gone thru one fact that mentioned incorrect oil will chemically reacted to this alloy to form some especially unwanted/damaging substance that will later slowly damage the engine. That's how we'll see those charcoal like substance that chock-up the engine.So remember yourself, in BMW's userbook, it's mentioned what's BMW oil designation used for the particular engine. Eg BMW longlife (LL) 01, 02, 03, 04 and so on. For eg Shell Helix ultra 5W/50 put LL02, Castrol Edge Sport 0W/40 put LL04.So make sure your lubricant has these BMW spec stamped on it. If you do, I don't see any reason why BMW service standards is wrong.
