What Is Mineral Hydraulic Oil? Explained

Mineral hydraulic oils are produced from crude oil fractions. Additionally, they’re refined to a level where they acquire enough lubrication properties. Then these oils are increased with an additive system. Generally, these additives serve various functions. Also, they may have rust-oxidation resistance and anti-wear properties, viscosity index-improvement properties, and more.

Depending on base oil and additive package quality, these mineral hydraulic oils can deliver performance like Valvoline traditional hydraulic oils. In addition, these types of additives can protect your hydraulic system from wear, corrosion, and water pollution. However, in this category, you can get hydraulic oils with detergent qualities.

Important Information About Mineral Hydraulic Oil

Mineral hydraulic oil is a high-quality oil which is used for performance braking systems, power transmission or in industrial machineries. The higher quality of the oil ensures you have extended service intervals. Actually, you can use this top-grade brake fluid in all braking systems.

If you want the best result, don’t mix this oil. And for best results, use 1 type of oil in your braking system. Besides this, this oil is hydrophobic and doesn’t suck moisture from the environment.

Common Specification for Mineral Hydraulic Oils

Accordingly, this specification covers standards for mineral hydraulic oils used in hydraulic systems. It needed refined mineral base oils with oxidation, rust inhibitors, and anti-wear properties.

Moreover, this specification covers lubricating oils before installation in hydraulic systems. Even so, it doesn’t include all mineral hydraulic oils.

Mineral oil requirements shall include viscosity, flash point, specific gravity, appearance, corrosion, and chemical acid number, but not be limited to.

The Difference Between Synthetic And Mineral-Based Hydraulic Oil

Most synthetic oils are either mineral based or synthetic. Mineral hydraulic oils come from crude oil fractions, whereas synthetic come from chemically produced base liquids.

Synthetic hydraulic oils come to provide higher physical properties compared to mineral oils. For example, there are high-temperature performance, oxidation-stability, and biodegradability.

What Is Mineral Hydraulic Fluid Audi

Mineral Hydraulic Audi Fluid has specially formulated properties that give it the highest hydraulic fluid quality. Nevertheless, it is specially designed for Audi, VW, BMW, Volvo, Mercedes, and Saab hydraulic systems.

Specially formulated for high tolerance hydraulic systems like hydropneumatic suspension, hydrostatic, power steering, and electronic-hydraulics. Mainly, this fluid has excellent low-viscosity flow characteristics for cars in a cold atmosphere.

Yet, it delivers high friction protection for vehicles subject to high-temperature conditions. Furthermore, it meets the modern hydraulic fluid system requirements for late-model European cars.

Technical Characteristics Of Mineral Hydraulic Fluid Audi

  • This hydraulic fluid offers only the best in German quality
  • Excellent shear stability at high temperatures
  • Maintains compatible viscosity at harsh operating temperatures from -40°C to 130°C
  • Better anti-foaming properties
  • Great corrosion protection
  • Dependable corrosive protection
  • Improved viscosities and friction behavior
  • Amazing thermal stability.

Application Notes:

Mineral Hydraulic Fluid Audi came for use from -40°C to +100°C and is recommended for the latest vehicle developments. Therefore, these anti-wear hydraulic fluids utilize an additive system to offer maximum protection. You can use this fluid anywhere that mineral-based hydraulic fluid is specified.

For example:

Vickers 35VQ25

Eaton/Vickers M-2950, I-286-S

Cincinnati Milacron P-68, P-69, P-70

Ford M-6C32

Denison HF-1, H-2, HF-0

General Motors LS-2

DIN 51524, Part 2

Mineral Hydraulic Fluid Power Steering

A power steering fluid is a hydraulic fluid used in a vehicle’s steering system. Basically, this fluid moves through the power steering hoses and pump. It helps the steering system control the car quickly. Most importantly, this fluid work like a lubricant and sealant, which prevent leakage and corrosion in this system.

Some fluids are water-based, and some come from mineral oil. The reason is that it offers excellent lubrication. Moreover, it can tolerate the high heat and temperatures that running a car engine generates. Other oils, like canola, silicone, and rapeseed, are sometimes used for hydraulic fluids.

How Often Should I Change The Hydraulic Power Steering Fluid?

Basically, power steering fluid, transmission, and brake fluid are all hydraulic fluids that aren’t interchangeable. Unfortunately, putting the wrong fluid in the wrong system can cause severe problems.

Always using the recommended fluid is the best. However, you must check the power steering fluid level at every oil change. Similarly, you must flush your power steering system after removing the fluid every 60,000 miles.

After flushing, your power steering system puts the new fluid into the reservoir. Please don’t reuse the old fluid; you also need to dispose of it properly.

FAQ ( Frequently Asked Questions):

Q. Is Dot 4 a mineral oil?

No, Dot 4 is a complex blend of polyglycol ether and glycol ether borate ester with extra oxidation and corrosion inhibitors.

On the other hand, mineral oil usually indicates to lubricant basestock-type element refined from crude oil. Chemically they are different and not interchangeable.

Q. Can mineral oil be used in a hydraulic system?

Yes, you can use mineral oil in your hydraulic system. It’s because standard hydraulic fluids are based on water or miner oil. You can use hydraulic fluid in hydraulic brakes, power steering systems, automatic transmissions, and more.

Q. Is mineral oil and hydraulic oil the same?

Well, you can say that hydraulic oil and mineral oil are entirely different types of oil in every aspect. For instance, they are different in their composition, origin, composition, or use and application.

Q. Is hydraulic oil mineral oil?

Hydraulic oil or hydraulic fluid is a synthetic or mineral-based fluid used to transfer power in the hydraulic system. We supply 99% of mineral-based hydraulic oils worldwide.

Final Word:

To conclude, mineral hydraulic oil comes with a highly effective additive to offer high wear protection. Ultimately, they are optimally alloyed and come for many applications that provide high-performance levels.

Overall, they offer the best performance in extreme conditions. Well, we are trying to cover complete information about mineral hydraulic oil. We hope you can get the desired information that you find here. Thanks for reading this article.
