Center dif oil weight?

It depends what you are planning to do with it.

For track purposes you probably want to stay in the 10-20K range. For bashing and general running I'd say that the 30K-50K range would be a good place to start, but if you still want wheelies and such then even heavier may be in order. 50K - 100K or so.

The revo uses crazy high diff fluids just becasue of the poor center dif design so its probably not a good comparison. Since you will be running a true 1/8 diff in your savage you shouldnt need to go as high as the Revo does. Even at 100K the revo center diff is too soft for most people. I hear of people running 300K and even 500K fluids in it.
