Although easy to miss, hydraulic systems are everywhere; without them life would become very difficult. Hydraulic systems may be as simple the floor jack in your garage or as complex as a crane. From machines and earth movers helping Sioux Falls to expand as a city to high dollar or vintage farm equipment out on the range.  Systems can be mobile, travel many miles to worksites, or others which spend their entire service life in one spot on a factory floor. Regardless of the type of system, they all operate in a similar fashion using the same types of parts. The hydraulic oil plays an important role in the health of each of these components and the overall smoothness and efficiency of the system.

Reservoir – The reservoir is simply the tank that holds the oil. On its way through the system the oil will spend a short period of time here. In that time, the oil has a quick opportunity to release air that’s gotten into the system so it doesn’t contribute to sluggish operation. All AMSOIL hydraulic oils have excellent air-release characteristics, maximizing this important benefit of the reservoir.  Another important function is to allow water to separate from the oil, allowing it to be drained. This is obviously most important for systems with larger reservoirs where draining can be accomplished easily.

Pump – The oil can’t be too thick when the machine starts in cold conditions. If it is, there’s a chance the pump will be damaged. On the flip side the oil can’t get too thin when the machine hits its highest operating temperature or excessive wear and poor performance can be expected. To ensure the viscosity remains within the system’s limits you can do one of two things. First, you could change to lighter or heavier oil depending on the conditions or, second, you could use a multi-viscosity oil to cover all the bases. The easiest way to identify oils that resist thinning and thickening is the viscosity index (VI). Oils with high viscosity indices resist viscosity changes with temperature far better than those with low VI. This fact can often save customers the expense and hassle of changing from lighter to heavier oil to meet the conditions. Most oil companies provide the VI number on their product data sheets.

Hoses and seals – Hydraulic oil must not chemically damage seal or hose material and should condition these materials to extend their service life.

Valves – Hydraulic valves are very close-tolerance items and even the smallest amount of varnish or dirt can cause them to bring a key piece of equipment to a halt. Keeping dirt out is simply a matter of good maintenance practices, but preventing varnish is pretty much up to the oil. Varnish occurs when oil breaks down under high-heat conditions. Just being synthetic helps AMSOIL hydraulic oils resist this breakdown, but we go beyond that with our HV Series Hydraulic Oil. These products are high-VI, multi-viscosity oils built with the ability to combat varnish formation. The product data page includes a graphic example of some high-temperature testing we’ve done against conventional oil.

Actuator – The actuator is the component that does the work. Everything else in the system is there to power and control it. As stated before, the common actuators are cylinders or hydraulic motors. How well they do their work often depends on the proper viscosity of the oil, so the same benefits that a mulit-viscosity provides for pumps are true for actuators. Now that I’ve covered the very basics of common components we’ll spend a little time on two of the most popular hydraulic oils we offer.

AMSOIL Synthetic Tractor Hydraulic/ Transmission Oil (ATH) serves two functions simultaneously. It’s designed to provide correct frictional characteristics for transmissions and wet brakes while performing as a premium synthetic hydraulic oil. It is used in many types of popular mobile machinery and provides excellent all-weather capability. That means the equipment that operates smoothly moving gravel around the farm in the summer will perform just as well removing snow in the winter without changing the hydraulic oil. This, coupled with premium wear protection, adds up to savings for the customer.

AMSOIL Synthetic Multi-Viscosity Hydraulic Oil has a solid track record of success. It exhibits high performance near the Arctic Circle as well as the hottest parts of the Deep South. Our Dealers have found a home for it in oil rigs, on ships, in mobile equipment and in large industrial applications throughout the U.S. and Canada. Not only does it provide all the benefits of multi viscosity oil, its unique ability to fight varnish formation has made customers happy by protecting high-value, critical systems.

Motorcycle Oil for your Motorcycle?

Motorcycle Oil for your Motorcycle? Ok, so it’s different but what makes AMSOIL better?

Motorcycle engines and automotive engines function differently, and the lubricants that service them have different requirements. Six crucial differences between motorcycle and automotive engines are outlined below to illustrate why oil engineered for motorcycles is the best choice for your bike.

  1. Operational Speed: Motorcycles tend to operate at engine speeds significantly higher than automobiles. This places additional stress on engine components, increasing the need for wear protection, and subjects lubricating oils to higher loading and shear forces. Elevated operating rpm also promote foaming, which can reduce an oil’s load-carrying ability.
  2. Compression Ratios: Motorcycles tend to operate with higher engine compression ratios than automobiles, which places additional stress on engine components and increases engine operating temperatures, placing greater demands on motorcycle oil to reduce wear. Higher operating temperatures also promote thermal degradation of the oil, reducing its life expectancy and accelerating the formation of engine deposits.
  3. Horsepower/Displacement Density: Motorcycle engines typically produce more horsepower per cubic inch than automobile engines, which exposes the oil to higher temperatures and stress.
  4. Variable Engine Cooling: In general, automotive applications use a sophisticated water-cooling system to control engine operating temperature. Similar systems can be found in motorcycle applications, but most are air-cooled or use a combination air/oil design. Operating temperatures in air-cooled bikes can skyrocket in stop-and-go traffic, promoting oxidation and causing oil to thin, reducing their load-carrying ability.
  5. Multiple Lubrication Functionality: Many motorcycles have a common sump supplying oil to both the engine and transmission. In such cases, the oil is required to meet the needs of both the engine and the transmission gears. Many motorcycles also incorporate a wet clutch within the transmission that uses the same oil.
  6. Inactivity: Whereas automobiles are used on a daily basis, motorcycle use is usually periodic and, in many cases, seasonal. These extended periods of inactivity place additional stress on motorcycle oils. In these circumstances, rust and acid corrosion protection are of critical concern.

No matter the conditions or the bike, AMSOIL synthetic motorcycle oils deliver the premium protection and performance your bike deserves. They are designed to control oxidation and maintain viscosity at higher temperatures, promote consistent clutch feel and lengthen clutch life, reduce engine stress and control wear and deposits in high-compression, high-temperatures motorcycle applications. V-twin or metric, AMSOIL has you covered.

Now for the Extreme test!! Hold on to your hat for this one, I was so impressed by this I thought I would grab the text from this AMSOIL brochure. So glad AMSOIL added this whole testing wing to the AMSOIL Center with bays capable of doing multiple tests at once. Watch the video which demonstrates the test laid out within the paragraphs.

red hot dynamometerV-Twins Get Hot

Harley-Davidsons* and other bikes with big V-twin engines generate significant heat, especially in low-speed parades, in rally traffic or on long climbs on hot days. Motor oil plays a critical role in cooling these big air-cooled engines, and even more so in low-speed operation with limited wind generated to cool the bike. If the oil can’t withstand the heat, its ability to protect your bike is compromised.

AMSOIL Synthetic Motorcycle Oil Protects in Extreme Heat

To demonstrate its extreme-heat protection qualities, AMSOIL 20W-50 Synthetic Motorcycle Oil was subjected to a dynamometer test designed to simulate conditions even more extreme than the demanding stop-and-go driving conditions of a motorcycle rally or parade route.

A 2012 Harley-Davidson FXDB Dyna Street Bob* motorcycle equipped with AMSOIL 20W-50 Synthetic Motorcycle Oil was subjected to a strenuous low-speed test cycle, with significant idle time broken by short bursts of engine revving and little to no air moving across the cylinders. Like most Harley-Davidson motorcycles, the Dyna Street Bob features an air-cooled V-twin engine, which relies on cooling fins arrayed along the cylinder walls to conduct heat away. To create the most-severe operating conditions possible, the electronic temperature controls, which safeguard the motorcycle when temperatures reach dangerous levels, were deactivated. The combination of low airflow and inoperative temperature controls allowed the test lab to subject the oil and engine components to intense heat not normally experienced in the real world. Cylinder temperatures reached more than 500°F, and oil temperatures exceeded 300°F – temperatures well into the range where oils begin to break down and often lead to catastrophic failure.

500°F is No Problem The extreme temperatures were no match for AMSOIL Synthetic Motorcycle Oil. After nearly 70 minutes of torturous testing and heat exposure, oil analysis revealed no change in oil viscosity and only minor levels of oxidation, TBN depletion and wear (see graphs).

Dyno Test Results

Not only did AMSOIL Synthetic Motorcycle Oil prevent the engine from overheating and seizing during the extreme dyno test, it did so without losing chemical integrity or ability to protect vulnerable engine components. This stands as further proof that AMSOIL Synthetic Motorcycle Oil provides outstanding protection in even the most compromising and severe high-temperature riding and idling conditions, providing peace of mind that your air-cooled V-twin is protected even in low speeds on hot days. Your bike should never get this hot. If it does, AMSOIL has you covered.
