Red Line heavy shockproof is the best fully synthetic gear oil for the MA70 Toyota Supra Turbo R154 transmission in our opinion! This is the price for (1) U.S. Quart. You will need to order (3) for your R154 transmission.
Red Line heavy shockproof contains the extreme pressure additives necessary for ultimate protection in road cars and racing vehicles, as well as friction modifiers (except NS) for proper limited-slip operation.
Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
Exceed API GL-5 specifications
Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
