Just got back my UOA from Blackstone for the last oil run in my ST with a Motorcraft filter.
Refilled with Castrol 0w-40 and a Royal Purple filter, I use the same oil in my 06 GTO and it keeps things simple. I am going to do 5k on this change, get a UOA with TBN this time to see how far I can carry this oil. My OLM didn't go off until 10,500 miles. I am not sure if I can handle pushing a tuned/modded DI turbo car to 10k oil changes, but we'll see what the TBN says next time, it's the only real way to know I think.
