Stock differential I'd use Toyota. For a LSD I'd personally get Redline fluid.

I use Amsoil Series 2000 Synthetic 75-90 Gear oil--but I'm sure other synthetics are just as good. You'll need 2 quarts (but the actual fill is 1.5 quarts). It's pretty much a lifetime fill as no real contaminants or high temps are seen in the rear differential.

Good luck.

Default SAME HERE SEATTLEGS400

I use AMSOIL SERIES 2000 75W90 Gear Oil. I changed mine out as soon as I got my car. I am an AMSOIL fan, and I have it all over my GS4.

if you want to drive the car normally... factory is great. if you have high horse ap try lucas, NEO synthetic or HKS. They are usually in the upper end of the strat. but worth it.

When I was at my dealer, they didn't stock any "Toyota" branded gear oil, they just sold some aftermarket brand (maybe it was Quaker State); hence why I went with the synthetic Amsoil gear oil (heck, the Toyota dealer's parts dept. was selling the Amsoil directly).

As for ATF, I would stick w/ the Toyota T-IV fluid, as it's specifically formulated for our cars.
