- Changes to Key Equipment
Alterations to essential equipment in a fluid system can affect both steady-state and transient behavior. Key areas of concern include:- Different types of pumps (mainline or booster) can significantly alter pump curves, efficiency points, and inertia.
- Minor modifications to block valve types, closing times, or loss characteristics can impact surge pressure generation.
- Replacing control valves or modifying control parameters (such as high-pressure shutdown setpoints or timing) can change the valve’s response to transient events.
- Adjustments to surge relief valve types, sizing, or pressure settings can alter the system’s protective measures.
- Changes to Operations
Operational changes may include:- Modifications to flow rate limits
- Adjustments in fluid properties
- Alterations to tank levels or pressures

Automotive Lift Repair Orlando Hydraulic systems utilize fluids to transfer energy and power, with the fluids referred to as hydraulic oils. What exactly is hydraulic oil, and where is it commonly used? What additional advantages do high-performance hydraulic oils offer to equipment and their owners? The Valvoline team has compiled answers to frequently asked questions regarding hydraulic oils.
Hydraulics are integral to numerous systems across various industries, where hydraulic fluids or oils are employed in a wide range of machinery and equipment. These fluids play a crucial role in sectors such as agriculture, construction, mining, steel production, shipbuilding, aviation, aerospace, chemicals, medicine, food processing, and environmental technology. In fact, nearly every industry around the globe relies on some form of fluid technology for either stationary or mobile applications.
Hydraulic systems and oils offer numerous benefits, including being an environmentally friendly alternative in certain cases. They possess high load-carrying capacities and, thanks to their anti-wear and anti-corrosion properties, provide essential protection for hydraulic systems operating in demanding environments.
What is Automotive Lift Repair Orlando Hydraulic Oil?
Hydraulic oil serves multiple purposes: it acts as a medium for energy transfer, provides lubrication, and seals components. Additionally, it cools equipment and transports contaminants away from the system.
Automotive Lift Repair Orlando Hydraulic fluids can be categorized based on their application: hydrodynamic fluids, known as power-transmission oils, and hydrostatic fluids, which are referred to simply as hydraulic oils. Hydrostatic applications involve high pressures and low flow rates, necessitating the use of non-compressible fluids to effectively transfer power within the system.
In the realm of lubricating fluids, hydraulic oils rank among the most crucial after engine oils. The three primary areas of hydraulics—stationary, mobile, and aviation—each require specific hydraulic mediums tailored to their operational demands. When used appropriately, hydraulic oils can enhance energy efficiency, minimize wear on machinery, extend maintenance intervals, and prolong the lifespan of equipment.
Types of Automotive Lift Repair Orlando Hydraulic Oil and Their Uses
Hydraulic oils are primarily categorized into mineral and synthetic types. Mineral hydraulic oils are derived from petroleum, while synthetic oils are chemically manufactured. Additionally, there are fire-resistant hydraulic oils suitable for sensitive environments, biodegradable food-grade hydraulic oils, universal mobile hydraulic oils (STOU and UTTO), and aircraft hydraulic fluids.
As previously mentioned, Automotive Lift Repair Orlando hydraulic systems are ubiquitous across industries, and a wide array of hydraulic machinery and equipment relies on hydraulic oils to function properly. The selection of hydraulic oil and its specifications depend on factors such as the design of the hydraulic system, pump type, operational temperature and pressure ranges, and environmental considerations.
Mineral-Based Hydraulic Oil
Mineral-based hydraulic oils originate from crude oil fractions and are refined to achieve suitable lubrication properties. They are enhanced with various additives that provide anti-wear, rust inhibition, and oxidation resistance. As petroleum-based products, mineral oils typically offer a more economical option compared to synthetic oils. High-quality mineral hydraulic oils, such as Valvoline HVLP and HLP, deliver excellent performance while providing protection against corrosion, wear, and water contamination.
Synthetic-Based Hydraulic Oil
Automotive Lift Repair Orlando Synthetic hydraulic oils are engineered to address the limitations of mineral oils. Composed of chemically produced base oils, they outperform mineral oils in high-temperature environments, exhibit excellent oxidation stability, and can be biodegradable. However, synthetic fluids come at a higher price point and may pose toxicity risks or compatibility issues with certain seals.
Fire-Resistant Fluid-Based Hydraulic Oil
Fire-resistant hydraulic oils, formulated from both mineral and synthetic base oils, are designed for applications where fire hazards are prevalent, such as in aviation and mining. While they are generally less effective in anti-wear protection compared to synthetic oils, they contain additives that enhance corrosion protection, reduce friction, and minimize foaming. These oils can come in various forms, including oil-in-water emulsions and water-based solutions.
Rapidly Biodegradable Hydraulic Oil
These hydraulic oils are developed with environmental standards in mind, making them suitable for both stationary and mobile applications in sectors such as industrial, forestry, mining, and earthmoving. Biodegradable hydraulic oils, such as Valvoline Ultramax Bio-46, are increasingly replacing mineral oil-based lubricants and can be derived from vegetable oils or hydrocarbon products.
Food-Grade Hydraulic Oils
Food-grade hydraulic oils comply with international regulations regarding base oils and additives that can be used in food-related applications. They are categorized based on the likelihood of direct food contact and the types of base oils used, which include special white oils and specific polyalphaolefin grades.
Universal Mobile Hydraulic Oils (STOU and UTTO)
Universal tractor transmission oil (UTTO) and super tractor universal oil (STOU) serve as hydraulic fluids for gearboxes and hydraulic systems in agricultural machinery and tractors.
Aircraft Hydraulic Oils
Designed for aviation, these oils can withstand high pressures and extreme temperature variations. Consequently, they must possess exceptional thermal stability, a high viscosity index, and be fire-resistant while remaining contaminant-free.
Additives in Hydraulic Fluids
The lubricating properties of hydraulic oils are enhanced through additives, which can improve various characteristics such as stability, anti-corrosion, anti-wear, viscosity-temperature stability, foaming resistance, and water separation. Additives are categorized into surface-active (e.g., wear inhibitors, rust inhibitors) and active (e.g., viscosity index improvers, anti-oxidation agents).
