Default What Diff and Transmission Fluid for Racing

Again, this is LeMons endurance racing. What viscosity, type and brand do you recommend for racing a 1984 RX7 GSL-SE in the transmission and differential, please check all that apply in the poll, and/or post a reply if you race or autocross.

For type I mean GL4, GL5, synthetic, non-synthetic, or blend

You guys have been a tremendous help in my Rotary education thus far, thanks.

Since nobody replied I will give my non racing experince advice.

For the diff use Amsoil Sever Gear 75W-110 or 75W-140.
I use their 75W-110 because I live in Houston and make about 400 whp.
Morepower and heat requires a heavier oil unless you add oil coolers and can keep the oil temps down.
Same applies to the trans.


For the trans Red Line 75W90NS or Pettit's Revomax Powerblend semi-syn 75W90.

I've always used Mystik jt-7 80w90. This stuff is aboslutely the best drivetrain fluid i've ever used.
