Looking at Castrol Euro oils and notice the 0w40 has a PA next to it, does anyone know what the PA is?
Castrol 0w40 PA
- Thread starter Trav
- Start date
Pressure Additive? 
I did note that on the SDS it says “Proprietary performance additives”. So perhaps it’s “Performance Additives”.
meaningless marketing term that sells product... "it's got electrolytes"
typical of castrol
It is on the front but the other 0w40 has A3/B4 next to it. Both have Porsche A40.

I figured that but the question remains what does PA stand for.
They probably wanted to one-up Mobil with the "what does the FS stand for?" questions on their A3/B4 Euro oils.
The Castrol Euro LL 5w30 (VW 504/507) and the separate 5w30 C3 products have disappeared, renamed to a single 5w30 K. What does K stand for? Some market genius at Castrol has too much time on their hands, is my guess.
Their tech sheet was updated a year ago and includes that "PA" reference but nothing at all that indicates what it means. They do refer to "Stronger Under Pressure" and "Advanced engines challenge the oil with increased pressures. These intense pressures cause friction...". Is this "pressure" reference new ?
It's different. There was a PDS for API SP 0W-40 with different numbers and I believe it included BMW approval but lost A40. That has now disappeared though.
in some eurpean sites there is also 0-40 R and 0-40 RSA
Did anyone actually see or use the 0W-40 SP though?
I routinely buy Castrol EDGE 0W-40 for several of my vehicles, and its been A3/B4, MB 229.5, Porsche A40, and API SN for a while now. Which, coincidentally is the same as the "PA" version talked about here. If there is an anomaly, it would be this mystery API SP version.
yes, 3 different 0-40
Also, Castrol used to sell 5W-40 and 5W-40 turbo diesel. Same product....
Castrol EDGE 0W-40 SP
See my thread above. I’ve used several 20L drums of the new SP formulation in my workshop. Seems like good stuff.
Approved for use in Pennsylvania.
Parrafin. That’s it. So obvious…
