all good then. there is a definate difference between mugen 100,000 and xray 100,000 i think the xray oils are "thinner" so to say.
If you follow one of the links above. The twf8 chart says that Mugen and Xrays oils are listed in "linear CST ratings".
But I've never compared them side by side. I don't go by the feel method. I've found that there many more variables associated with a differential when you spin it in your hand. ie orings on the outdrives, and how much fluid you put in the diff. I only go by how the car feels on the track.
Pass you soon...
