• Similar to SAE 5W40/10W40 engine oil viscosity
• Quicker shifts, perfect synchronizer coefficient of friction
• Safe for brass synchros, lacks reactive sulfurs that damage
• Gear protection & longer synchro life
• Eliminates notchy shifting, even when cold
• Satisifies gear oil viscosity requirements of 75W, 80W & motor oil SAE 40, 10W40 & 15W40
