Any opinions on using Rotella T 15w-40 in a 400sb with about 100,000 miles and some pretty good leaks. I need to change the oil today and I've got a case of it handy.

at least it did mine when i ran it, drained it out, looked like black water.Drey said:I have a 400 SBC that is gettin rebuild and bumped up a few notchs. I had planned on Rotella T for oil, what weight do you guys recommend?
