100% synthetic lubricant for mechanical transmission. This product was specifically designed for high-performance competition vehicles with mechanical, synchromesh or unsynchronized transmissions, differentials, gearboxes and hypoid differentials without a limited-slip system subjected to shocks, heavy loads and low revs or to moderate loads and high revs that require compliance with API GL-4 / GL-5 and MIL-L-2105D 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. This viscosity grade (90) provides excellent oil film resistance at high temperatures and / or reduces transmission noise. Guarantees 0% shear loss: non-shear oil film under extreme conditions. Suitable for joints of all kinds and yellow materials used in gearboxes.
