My IS is due for her 60000km service.
I was wondering if i should provide replacement engine oil ( Shell Ultra or Mobil 1 Synthetic ) or
should i just go with the Castrol Magnatec they provide.
The main reason for the change is to see if there is a reduction in engine noise , i reckon my car is noisy.
Only thing making me think twice is if the dealer actually discovers and accepts that their is some kind of mysterious prob with my car, they'll say im not using recommended products.
