Zinc is not necessarily better for high RPM motors. The benefits of ZDDP are greatly exaggerated, especially for modern engines. There are newer additives that offer the same or better performance.

Unless you are running some old-school flat tappet engine, I see no need for elevated ZDDP.
There's a TON of info on the BMW bike sites on zinc and flat tappet motors like the boxers BMW used to build.

They have the same level of zinc despite the different API specs.

0W-30 has a zinc max for SM and SN. 0W-40 doesn't

The 0w30 is SL rated.

So 0W-30 is not capable of SM and SN

Castrol down here, with the 5W30 A3B4 make no effort to "do" SM/SN.

They only claim SL, but meet the "performance requirements" of SM/SN, while exceeding the phosphorous.

Hi,
Shannow - Castrol clearly see a market place niche here for a 5W-30 A3/B4 product - a smart move IMO

 

[Shannow]

Doug, agreed wholeheartedly....that's why there's 10L of it waiting for my Navara's next OCI.

And here it is...

Alas, we already knew it contains titanium, thanks to the VOA.

Ah!. Must check local WM for Ti lettering...

I think personally Castrol made mistake with 0W40 oil. They want to compete with established M1 0W40, instead of going with 5qt jugs of 0W30, to offer something different.
Also, one of the problem Castrol has are pds sheets. When I look at m1 sheet I know what I am buying. With little research you knew what you buying with 0W30 GC. Now no one knows what is HTHS of this 0W40 GC, what is pour point etc.


HTHS is on the Castrol USA site:

It's not the actual HT/HS. It's just a minimum as required by ACEA spec.

I do not think that is Castrol we are getting int he U.S. or there is big difference of what Castrol claims and what actually is in the bottle:
Catrol 0W30&0W40

Like QP said, that is just required ACEA minimum.
