High performance or regular synthetic??

I'm under the impression you're not based in the US, so
obtaining M1 Racing, Redline, Amsoil, HPL isn't that easy?
While I have no clue which car you're driving and which
kind of racing you plan with it I'd still tend to recommend
using an oil with a true Porsche A40 approval.
Without some more comprehensive details it won't even
be possible to answer your question. That said, nobody
seems to have heard about United.

Thanks for the info, I guess I will stick with known brands.
