Just got mine back from dealer for airbag and rear brake line recall. i'm at 413,000kms. Cobb Stg 1 with BNR 16g, invidia up pipe and IPT oil feed.
Had to replace passenger side valve cover gasket recently, otherwise oil-tight. It only uses oil between changes if i cane it, just use the torque for passing and not revving too high keeps it alive.
