I'm just curious is it ok to practice and race SC Truck 4x4 with oil in the center diff and the stock grease in the front and rear as I don't have enough time to do all three before the weekend's races.

It will be ok, but probably a little off or hard to drive. The grease is really there to keep the gears from tearing each other up. If really has no effect in distribution of power. Hence the reason silicon oil or diff fluid has different viscosities/ thicknesses.

I would try to do all 3 looking at different set-up sheets to figure out what oil you need in each diff. If at all else, get the front done at the track and for go the practice to get your car up to snuff.
