Motul Motylgear 75W-90 is a Technosynthese extreme pressure lubricant for synchronized and non-synchronized manual gearboxes, gearbox differential units, transfer boxes and hypoid differentials without a limited slip system. It meets API GL-4 and GL-5 along with MIL-L-2105D, and the synthetic base stock holds its SAE 75W-90 grade after shear testing to SAE J306. Motul recommends it for gearboxes that are hard to shift or noisy, since the low temperature fluidity reduces the effort needed at the lever while the engine and driveline are still cold. The fluid also carries anti-corrosion and anti-foam additives and is compatible with the seals and yellow metals used in gearbox construction.
