Lightweight ShockProof®

• Film thickness greater than an SAE 75W140, yet low fluid friction like 80W gear oil or 30W motor oil
• Excellent low-temp flow, improved cold shifting
• For racing differentials under moderate loads
• Popular in racing transmissions like Hewland and other Road Racing dog-ring boxes, Bert and Brinn for Stock Cars, G-Force, and Liberty clutchless for Drag Racing

ABOUT RED LINE GEAR OIL FOR MANUAL TRANSMISSIONS

• Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
• Red Line offers lubricants to pinpoint nearly every transmission application
• MTL & MT-90 are not for use in differentials with hypoid gears
• Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
• Excellent for high- and low-mile transmissions
• Compatible with petroleums and other synthetics
