I'm now using the Royal Purple 5w-40 as well. I was able to order a case through my local NAPA. It's pretty spendy, but I think worth it. Before I switched, I placed a call to their tech support, and they were very helpful, and answered all my questions.

Because the 5w-40 is ACEA A3\B3 rated, I guess the additive package had to come from Europe.
