Akros Universal 15W-40 is a universal multigrade oil (S.T.O.U.) for aspirated and turbocharged diesel engines of all types and power ratings, and for transmissions, oil bath brakes, axles and hydraulic systems of tractors and farm machinery in general. As a Super Tractor Oil Universal, it is designed as a single fluid for the engine, transmission, brakes and hydraulics of a tractor, simplifying lubrication and stock-keeping. It is an SAE 15W-40 oil meeting API GL-4, API CE, CCMC D4 and UNI 20153-NOM C1 specifications, with ZF TE-ML 06B, 07B, MIL-L-2104 E and MIL-L-2105 performance levels, and the SDFG OU1391 specification.
