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.
