AKROS GEAR EP 90 LS is a transmission oil with extreme-pressure (EP) characteristics for the gearboxes, final drives and differentials of tractors and farm machines. Its friction-modified formulation makes it suitable not only for conventional differentials but also for self-locking differentials fitted with limited-slip (LS) systems, where correct friction behaviour prevents chatter and wear of the clutch packs. The SAE 80W-90 grade delivers a typical viscosity of 14.7 cSt at 100 °C with a pour point of -36 °C, so the oil flows readily on cold mornings while keeping a robust film under the heavy, shock-loaded conditions found in agricultural drivelines. AKROS GEAR EP 90 LS meets the API GL-5 performance level, MIL-L-2105 D and the SDFG OP1705LS specification for SAME Deutz-Fahr Group machinery. Available in 20 L and 200 L packs.
