Oil Pressure
mine is around 30 PSI when really hot outside and fully warmed up, but i use royal purple 5w-30 and i think it thinned out by now so thats why my pressure is like that. i will be switching to german castrol 0w-30 this weekend though to see if it makes a difference.
i used to run 5w-30. Id get 55-60 psi when first starting it, then hot it would idle down to 40 psi, but never below. However with my new cam I was told that to run either 5w-40 or 10w-40, so i purchased some amsoil 10w-40 and put it in a few days ago and it def doesnt thin out as much and oil pressure holds more even after a few hard runs on the street. I would recommend a 5w-40 or 10w-40 synthetic to anyone.

Verdad Gallardo Well with mobile 1 now charging an arm and a leg id say just get a 12 quart case of amsoil as its within $5 of the mobile 1 12 quart case. They have 10w-40 and I believe 5w-40 too. I dunno though about 0w-40 but just check out their website.

With GC and at 200F oil temps, my idle oil pressure is 29psi. Mine is automatic with a 700rpm idle (an M6 would have a higher idle, and therefore higher idle oil pressure)
At 70mph and 200F oil temps, my oil pressure is 42-44psi.
One thing I love about GC is that even when the oil temps get hotter, the pressure does not drop very much. Although I've also never seen my oil temp get hotter than 230F. It typically runs 195-205F except when it's above 80F outside.
