Yes, there is a difference. Using slippery oil the plates will be having less friction and because of this everything will be a bit smoother and your plates will have a longer life. If you go for thicker oil, like a non lsd oil without friction modifiers then your differential will lock sooner and be louder (you will really notice a difference when you are running an agressive diff used for drifting.) Except for this your plates will will not last that long but as you are drifting anyways you will not notice that much of a difference in durability.
