HOLLLYYYY SHEEET LM FINALLY TOOK MY EMAIL TO HEART AND API (re, as they were api certified back in the 2008/2009 and before iinm) CERTIFY THEIR PRODUCTS
anyways.
can't just look at TBN alone, other specs (PDA/MSDS etc, for VI, actual viscosity ratings, HTHS, flash points etc), or VOA (virgin oil analysis)/UOA would be better.
example, even if TBN is 9, however other additives aren't good enough (say, calcium) or strong enough, the rate may deplete faster than say, a TBN 6.
if anything, i still had 6.3TBN after 8500 km on the amsoil signature series 0w20.
although the lab guys mention that TBN depletes at very high rate during the initial stages of the engine oil, however it'll start to slow down half way, which does make sense as the 8500km rate of TBN depletion certainly wouldn't be able to make it till 40k km (25k miles).
Then there's always other additives, friction modifiers etc.
hence the user feedback of "x oil smoother than y oil"
API is always the safe bet as chances of going wrong is much lesser. remember, it's NOT easy to get it certified, as you need money (some companies choose not to certify as they don't want to pay, and/or add to their product cost), and the fact that emissions/cat-con protection etc is taken into account, while at the same time you have to protect your engine wear on very stringent tests at insane temperatures/hours.
i'm comfortable on the signature series/300v as i'm going to do UOA anyways... and they are products that represent the very company/brand itself. (should look at 300v ads/youtube videos rofl)
Ok ok. So if I can't get the amsoil, I suppose I'll get the LM Special Tec AA, which is API SN certified and is available near my area.anyways.
