Hi growler,
Mine is a PI car.
Hear they used mineral oil for first round ( not sure any truth).
Anyway for the peace of mine when to change today at autospritze ( was with them since my last car) when it reach 1k.
The technician Barry has clocked 10 years with pml and said he seen many oil slug when pml changed from castrol to mobil.
It's especially true on twin turbo engine as I was told.
Went with his recommendation for castrol. Seems ok so far, did not notice any difference from my last motor oil.
I wot today for the first time at 5k rev, wow pull is shoik!
The downloaded M powered meter app on iPhone shows max g force is 0.9 G
Will monitored for a few weeks. May changed back to mobil 5w 40 as suggested by kon for the next service.
Don't see the need to spend $250 just for oil change.
