100% synthetic lubricant for mechanical transmission. This product was specifically designed for high performance and competition vehicles with mechanical, synchronized or unsynchronized transmissions, differentials, gearboxes and hypoid differentials without limited slip system subject to jerks, heavy loads and low revs or moderate loads and high revs that require compliance with API GL-5 standards. This product is a synthetic extreme pressure lubricant that offers effective wear protection, improved high temperature resistance and longer life. Its very high lubricating power reduces friction and wear and reduces the effort expended on the lever to change gear even when cold. Contains a specific friction modifier to prevent noise and limited-slip differential drag. Offers improved transmission efficiency compared to 75W-140 grade. Guarantees 0% shear loss: non-shear oil film under extreme conditions. Suitable for joints of all kinds and yellow materials used in gearboxes.
