What is a good substitute for hydraulic fluid?

“It is a common practice in the construction and mining industries to use engine oil SAE 10, SAE 20 or SAE 30 with the lowest API rating as a substitute for hydraulic oil ISO 32, ISO 46 or ISO 68, respectively for hydraulic systems of heavy equipment.

Is hydraulic oil the same as Jack oil?

The answer is clear, that hydraulic jack oil itself is a hydraulic fluid that is used for power generation, sealing, heat transfer, lubrication and more. But, we differentiate these fluids on the basis of its properties. Most of the commonly used hydraulic jack oils are mineral oils that are insoluble in water.

What is ISO 32 hydraulic oil?

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.

What oil can I put in my jack?

If you don’t have access to hydraulic jack oil, you can use machine oil or 10/20W lightweight motor oil in a pinch. Automatic transmission fluid will also work if you don’t have any other options.

Can you use canola oil as hydraulic fluid?

The combination of a growing desire for biodegradability as well as renewable, less-costly alternatives, suggests that canola oil-based products can replace petroleum-based hydraulic oils, white and food grade mineral oils and synthetic polyol esters, especially where fire resistance is a concern.

What color is vegetable hydraulic fluid?

blue color, vegetable base, will burn, natural rubber seals.

Can 15w40 be used as hydraulic fluid?

For a pump requiring ISO 46 or ISO 68, the heavier viscosity 15W-40 will pump less efficiently than an designated hydraulic fluid. Drive train fluids are also sometimes used in heavy equipment hydraulic systems, says Snyder, for product consolidation or when there are cross-contamination concerns.
