What shock and diff oil for rustler?

[A RC Dude]

Ok, I need to get new diff and shock oil for my rustler. I don't think my rustler's rear shocks (alum evader shocks) and my right front shock leaked half it's oil when the cap somehow got screwed halfway out (when i replace the oil, i'm going to glue the cap and the bottom part so thay want leak. so i've got to get the oil's weight correct). and as far as the diff oil, what brand, what weight would be best?
