Does it matter what hydraulic oil you use?
Does it matter what hydraulic oil you use?
It doesn’t matter how good the other properties of the oil are, if the viscosity grade is not correctly matched to the operating temperature range of the hydraulic system, maximum component life will not be achieved.
What is HLP 46 hydraulic oil?
The hydraulic oil HLP 46 is used as pressure fluid in industrial and mobile hydraulic systems. It must withstand high thermal loads, prevent corrosion when water is supplied and minimise wear when mixed friction occurs. The designation HLP 46 is composed of “HLP” and “46”.
Is VG 46 the same as AW 46?
AW 46 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 46. This is the thickness of the fluid tested at 40 degrees Celsius. ISO VG 46 is the most popular grade due to its middle grade flow properties with a thickness that is equivalent to a SAE 15 weight lubricant.
What weight is ISO 46 hydraulic oil?
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 is HLP grade oil?
Valvoline HLP hydraulic fluids are based on highly refined mineral oil and enhanced with a stabilized zinc additive system. Formulated with high quality mineral base oils and specific additives to protect against corrosion, foaming and sludge forming.
What is ISO viscosity grade?
The International Standards Organization Viscosity Grade, or ISO VG, is a numerical rating of the viscosity of oils and lubricants as established by several organizations in 1975.
Which is the best grade for hydraulic oil?
While most hydraulic oils are measured with the simple ISO grade, there are oils out there with anti-wear properties that are measured separately. For instance, you may see AW 46 hydraulic oil while looking around. These oils perform at the same grade as their ISO counterparts.
How is hydraulic oil different from regular oil?
Hydraulic oil has to function differently than most of the oils which exist on the market. While oil is one of the most commonly used lubrication technologies in the world, hydraulic oils have some requirements which simply aren’t there for regular lubricants. Hydraulic oils have to be able to perform under pressure.
Which is hydraulic oil should I use in my Power Pack?
According to DINISO 2909 oil viscosity changes versus temperature, Viscosity Index (VI), is normally between 90-110. VI above 130 are largely insensitive to temperature change. A viscosity range of 12-80sCt is recommended for a large range of commercially used hydraulic equipment.
What should the viscosity of hydraulic oil be?
For instance, the viscosity of ISO grade 46 hydraulic oil at the optimal temperature is going to be 46cSt. If significantly below that, then the oil is going to be significantly thicker and you may need to ensure that you’re using a fluid with a lower viscosity to keep things operating properly without adding additional wear to the system.

Which is better hydraulic oil aw or aw-46?
Lower numbers indicate thinner, more easily flowing oils. As such oil rated as AW-32 is neither better or worse than one rated as AW-46. The numbers refer only to the viscosity – AW means Anti-Wear – not to the quality; oil quality is dependent upon the manufacturer.
What kind of hydraulic fluid do I Need?
They should be able to look up the manufacturer recommendations for you. Once you find the specified weight of oil you need, you may find that some hydraulic oils are labeled “ISO,” and others “AW.” These oils are the same weight, but AW oil also has anti-wear properties, hence the name.
