A unique product with the viscosity of 75W90 gear oil but lower internal friction similar to that of an ATF. Used when temperatures are not high and when the maximum power output is required such as in stock car qualifying laps. Used in low-power road racing transxles like Formula Vee and low-power SCCA Production classes (dog-ring type, generally not sycro application where this product can be slippery).
