What kind of hydraulic fluid goes in a car lift?
Hydraulic fluid is the only recommended fluid/oil for your lift. AW 32 or AW 46 is the proper type of oil recommended by the lift manufacturer. Synthetic oil, automatic transmission fluid, and other substitutes are not recommended. Common hydraulic fluids are based on mineral oil or water.
What type of hydraulic fluid should be used?
The most commonly used hydraulic fluids are mineral oil-based ISO 32 and ISO 46 fluids. The numbers in their names represent fluid viscosity in centistokes at 100 °F.
What is ISO 32 hydraulic oil used for?
ISO 32, 46 and 68 grades are most commonly used for hydraulics with vane-, piston-, or gear-type pumps, especially where pressures exceed 1000 psi. They can also be used to lubricate lightly loaded reciprocating compressors.
What’s the difference between AW32 and AW 46 hydraulic fluid?
R&O is approximately a 10 weight oil with the additives. AW32 is approximately a 10 weight oil with the additives. AW46 is approximately a 15 weight oil with the additives. AW provides many of the advantages of premium hydraulic oil at a moderate price.
What’s the difference between ISO and AW hydraulic fluid?
The ISO classification for these oils is HL. AW stands for anti-wear – R&O oils with an anti-wear additive package. The ISO classification for these oils is HM. The ISO classification is HR for VI-improved R&O oils and HV for VI-improved AW oils.
What is the difference between AW 46 and AW 32 hydraulic oil?
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. The hotter the temperature, the thinner the oil becomes and the colder the oil, the thicker.
