I hope the pdf I'm linking to below doesn't change the date each day, but if not, it looks like there's a new spec sheet for GC and it's Syntec siblings. Interestingly, GC (0W30) and BC (5W40) are the only two Syntecs to not be rated "SM"... I assume due to the desire to put protection above enviro concerns with these particular oils. (Hopefully, I won't trigger an avalanche of dispute over the above comment! [Eek!] ) Anyway, here's the new Syntec Spec Sheet. [Smile]

Woo-hoo! GC (0w-30) now officially meets GM-LL-025 spec! I can now run it under warranty in my Saab in accordance to the oil monitor. [Happy]

I don't think Castrol ever lists those in their oil tech documents. [Frown]

That's what I've been waiting to see. It lists the 0w-30 meeting the MB 229.5 spec which means this oil is almost certainly the Longtec oil in Europe. They even call it the European formula. This is probably good stuff but wear is probably sacrificed for TBN retention. We'll just have to see...

medic, I don't think the target audience is concerned about SM...more about the ACEA and MB ratings.

The ACEA A3 rating means that it has an HT/HS of at least 3.5.

Castrol considers HT/HS, Noack Volatility, and other important specs as "proprietary" information. It's so cheesy, in this age of greater transparency. Despite what the Amsoil bashers say, Amsoil provides more specs on their oils, greases, and ATFs than anybody I know.

Agree. LOL BTW, the Amsoil marketing strategy sucks balls. Bashing or stating a fact? [Big Grin]

The SM rating would probably be a step backward in a high quality synthetic oil due to reduced ZDDP levels.
