Hi ausgnome, I'm using Mobile 1 in mine I know that you pay thru the nose for it but I find we don't have to much choice here in Aus a lot of the other oils say that they Synthetically fortified or some other high felutine words so I go for mobile 1 that says fully synthetic. I guess there is other oil that will be just as good but at the moment I'm sticking with what's recommended in the Manual
Ben.
