Description. WILL Hydraulic Oil AW-68 is premium grade oil designed for use in all kinds of hydraulic systems and moderately loaded gearboxes. The high viscosity index fluid displays excellent viscosity control when under high levels of mechanical stress and across a wide temperature range.

What does Aw stand for in hydraulic oil?

AW stands for anti-wear – R&O oils with an anti-wear additive package. The ISO classification for these oils is HM. MV stands for multi-viscosity.

What does 68 mean in hydraulic oil?

The numbers 46 and 68 refer to the ISO Viscosity, and all hydraulic oils sold in Australia use this number grading system. Viscosity is oil’s resistance to flow and the grading system relates to this resistance at a temperature of 40 °C.

SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100.

What weight is AW 100 hydraulic?

AW 100 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 100. This is the thickness of the fluid tested at 40 degrees Celsius. ISO VG 100 would be considered thick for a hydraulic and flows equivalent to a SAE 30 weight lubricant.

AMSOIL Synthetic AW Series Anti-Wear Hydraulic Oils are shear-stable, long-life lubricants based on high-quality synthetic oil technology.

Which hydraulic oil is thicker 68 or 46?

The hotter the temperature, the thinner the oil becomes and the colder the oil, the thicker. So, for example, a hydraulic system operating in a cold climate like Tasmania would run better with a lower viscosity grade of 32. Here in Perth, 46 and 68 are better suited to our climate.

Can you mix ISO 32 and ISO 68 hydraulic oil?

“Is it all right to mix an R&O hydraulic oil with an AW hydraulic oil in a hydraulic application?” Mixing oils with different additive packages is never recommended. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.

AW-32 is neither “better nor worse” than AW-46. The numbers refer only to the viscosity, not to the quality. Quality of the oil is determined by the manufacturer. For Atlas above ground lifts, AW-32 (lower number than AW-46) will flow “better” in colder weather than AW-46.

Is aw32 the same as ISO 32?

AW 32 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 32. This is the thickness of the fluid tested at 40 degrees Celcius. ISO VG 32 has good cold weather flow capabilities and its thickness is equivalent to a SAE 10 weight lubricant.
