Yep, the compressor, injectors, and everything else on these motors need the good stuff. It burns so little oil, total cost of opti oil vs black max is probably about the same or less.

According to my research, it was the early 3.0 motors that had issues that were eventually resolved but the 2.5 litre motors never had those problems.
