Using 10-60w fully synthetic?
I am track daying my car frequently this year and want to protect the engine as much as possible, i have no oil cooler and when the engine gets real hot eg, WOT on the dyno being held on the brake for a while, i noticed oil pressure can drop to 19psi at idle, it comes back up to 30psi idle after it cools down. I was thinking a higher hot temperature grade could give me more piece of mind. There is Castrol edge Sport over here and it is a 10-60w grade. Cant hurt can it? I am in the UK so dont have the same choice of oils as you guys. Cheers.
ETA i am running 5 40w fully synthetic GM oil at the moment
