I'm going to do my 600mi service. I've got the filters, but could only find
10w40 oil.Is this going to work ok? My book says 10w30. What are you guys using?
Mick
I use 10w40 because that is the only oil I sell that is not energy conserving . I think that is more important than the weight of the oil which in this case , 10w30 and 10w40 are very close . I use Wolf's Head .
