Currie 250W Racing Gear Oil is formulated using highly refined petroleum base stocks and select additive systems to improve gear protection and high-temperature stability. Special high adhesion polymers focus on shear stability, thermal stability, and high shock load protection. Racing Gear Oil carries a higher concentration of extreme pressure, anti-oxidation, anti-corrosion, and anti-foam additives to prevent degradation.
Warm-up is required - Due to the high-viscosity (thickness) of 250w gear oil, the rearend should be allowed to warm-up prior to high-load/high-speed driving. A warm-up can be achieved by driving at low speed/low load or by placing the rear axle on jack stands and allowing it to idle in gear for 5 to 7 minutes.
