firs report, got the car in February, drive it HARD. this was dealer fill, so no idea what oil exactly.
current oil is liqui moly 5w40, will be going to Castrol 0w-40 on the next change, my mechanic did not have it.

Wow.... 2.3 TBN after 4,000 miles?

Silicon, aluminum and iron are high, might want to look for AF leak causing abrasive wear.

Have you noticed any reductions in performance going from a 20 to 40 weight oil?

Normally 40 weights make engine smoother and quieter but they also make it feel slower and heavier compared to lighter oils..

40wts are so underrated. It will provide the proper lubrication your 400HP engine requires.
