I second this. Rotella T6 is wonderful.
It also has additives similar to a high mileage oil that causes rubber seals to swell, reducing leaks and things like that.
Lots of turbo guys love this oil also. Interestingly, it reduces oil consumption on turbo cars. STI/EVO guys love it.
I track my car as well and this is all I use (along with a good oil filter)
