same here. have used it in several FE & small block engines totaling over 120,000 miles trouble-free miles. Currently have 44,000+ miles on a vintage Paxton equipted 289 Hi-Po engine using Mobil 1 15-50. No leaks, no measurable wear. Doesn't need zddp either.
I do use Mobil 1 0w-40 in the winter, and add a small amount of Cam Shield.
