Here is the elemental information on the CK-4 series.
To answer the questions in advance the aluminum content comes with the high concentration of Molybdenum. It is part of that raw material. The 7 ppm Silicon is defoamer.

I’ll check out the website. But any acea c3 oils?
3.0l duramax here and am more than likely jumping up to a c3
With a TBN >13.5, what is your ash number? Lots of anti wear/acid neutralizing metals not good for DPF's.
is it possible to order the products from outside the US? Amazon had it.. but its out off stock right now 
I would like to know the ash numbers too.

My zero turn is gonna love this!
I’m pretty happy so far with the ck-4 5w30 HDEO oils. Great quality and work by David and the HPL staff
Does anybody know the ash content of these oils outa curiosity?
I was debating for awhile on the next oil to try in my 6.7 Powerstroke, and after chatting with Dave, the super fast and helpful response was enough for me to give HPL a try, just received this week, looking forward to getting it in there. Was undecided on trying a 10w30 of sorts, but decided to go with another 5w-40 in HPL.

Anybody who knows David Ward can vouch for how solid and cool he is...and busy.
Either oil should work in 6.7 PS.
