Message	The engine oil message boards have for years been raving about how good the Castrol synthetic 0W30. Some other turbo car owners, such as WRX owners, have used it with good results on their used oil analysis. I'm just wondering if anybody in the 300ZX community has used it on their Z and what their experiences were. I am aware that the owner's manual specifies 10W30 and specifically warns against using 5W30 at higher ambient temps. However, my understanding is that this is to prevent premature breakdown/shearing. Since this is not a problem with the better synthetics, can we safely run 0W30? Dan
