Here's the latest on my Legacy GT. The Rotella is proving to be a solid choice for this engine. The copper is still a bit high, but I suspect that is an interaction between the Rotella chemistry and the big, copper oil cooler. The fuel is a bit high likely because the warm-up for this change was all at idle while I changed the coolant and P/S fluid.
