Which fluids should I use in my Toyota Supra?

I recently purchased a used Toyota Supra and want to make sure that I am using the correct fluids. Which fluids should I use for the engine, transmission, and differential?

As a Toyota Supra owner, I recommend using synthetic oil with a weight of 5W-30 for the engine. For the transmission, you should use Toyota Genuine ATF Type T-IV Fluid. And for the differential, use Toyota Genuine Differential Gear Oil.

I've been working on Supras for years and have found that using a high-quality synthetic oil with a weight of 5W-40 works well for the engine. As for the transmission, I recommend using Redline D4 ATF. And for the differential, use Redline 75W-90 Gear Oil.

In my experience, using a conventional oil with a weight of 10W-30 works just fine for the engine. For the transmission, I recommend using Valvoline Multi-Vehicle ATF. And for the differential, use Valvoline High Performance 80W-90 Gear Oil.
