    Don't panic. 3720 miles on Mobil 1 Synthetic 5w30 in my car and it was still within range for 5w30 (56.6 that needs to be between 55-62)

    Yeah.. I think it's more of an issue in high power builds than anything. I would just wait till it's time to change, then switch to something else. Plenty people run it for the life of the car with no issues, but if I know there's something better out there for the same price I'm going to use the better oil.

    Good deal. I'm in an 02 WRX with 103k miles if that makes any difference. Basically a bone stock car, however.

    The German Castrol has a red label, and it says “Made in Germany” on the back.

    What's so great about the Castrol German blend vs regular Castrol synthetic?

    German Castrol is a real synthetic group IV (PAO) that uses esters that are derived from PAO. This is a unique chemistry. Most esters are group V. It has shown extremly low wear in Used Oil Analysis (UOAs). The U.S. Castrol is a different animal. It is hydrocracked (highly processed) mineral oil that legally can be labeled as synthetic. It has a decent additive package but cannot match GC.


    Basically, it's completely different..

    In the US it is questionable whether a regular Castrol "synthetic" exists. After the term "synthetic" become more legal than chemical in the local market the makers started labeling hydrocracked / GrIII stuff synth, and they were within their rights to do so. The imported oil wasn't allowed the same lenience for its local market so it's a true synth - or at least it was last I checked.

    Castrol are not alone in doing this; as a sign of how the mighty (in their own minds) have fallen, Amsoil had done the same thing with their XL series products. Ultimately it doesn't matter what the synthesis process is, what matters are the oil analysis data from a customer's motor. Given that I'd use any modern API oil that meets the maker's spec and not worry all that much.

    Also, the imported Castrol is green in 0W-30 at least while it is new or fresh (I do not know about the 5W-40 stuff that was sourced from BE).

    Yeah, I ended up switching to Shell Rotella T6 after reading all the hysteria over Mobil 1 shearing down, but I didn't rush it. Just changed it at the next scheduled interval.
