I'm just wondering what
OIL everyone uses in their WRX (especially those with a GC8), I've just purchased an MY00 gc8 rex and I'm leaning towards using Penrite 10w-40 or Valvoline 10w-40 both Fully Synthetic
.
I've been told that the oil currently in the car is Penrite 5w-40 Fully Synthetic. Will their be any harm in putting Penrite or Valvoline 10w-40 Fully Synthetic in my next service?
I've heard Castrol Edge is quite popular? Why is this so, and are there any brands that I should stay clear of?
Thanks guys
Ashby
