The Right Hydraulic Oil Can Make a Difference.

AMSOIL formulates a hydraulic oil for just about any operating condition.

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.

Diesel Oil Selection Guide

Diesel Oil Selection Sioux FallsAMSOIL Diesel Oil Selection Guide

From a “one size fits all” to synthetic oils to match specific needs.

The diesel oil selection here often causes some confusion because they are made for different purposes and the value of one may depend on the use of the truck or the year model. So here I have listed some things about each for you to consider in your decision making process.
As diesel trucks both light duty and commercial OTR are quite the financial investment, always refer to the individual product data bulletin found by using the link to the PDF at the bottom of each product page for more specific information. Please call me at 605-274-2580 with further questions.

Generally the AMSOIL Diesel oils can be categorized in two groups: Longest OEM interval or Premium Extended Interval. These days Sioux Falls drivers can really put on the miles and AMSOIL’s Synthetic Diesel Oils can increase your drain intervals up to three times longer.

AMSOIL Corporate’s #1 Pick
I’ll start with the one one premium product compatible for all diesels – all years – The Premium 100% CJ4. Available in both 5W-40 (DEO) and 15W-40 (DME) this industry leading anti-wear diesel oil lasts up to 3X longer OEM intervals (per notes on package) and offers maximum protection. For more information on this important addition to the industry please visit the specific pages linked above.
Most customers buying AMSOIL are enthusiasts and only buy the premium products thus why this one is becoming the best seller on its merits. Primarily it’s ability to withstand the fuel dilution issues of modern diesel engines equipped with DPF. Dependability and protection when it’s needed.

Older Diesels
For those with older diesels who want our legendary high zinc, long life, chose the Diesel and Marine 15W-40 (AME). It’s great for all 2006 and earlier diesels especially those which may suffer from high soot buildup as this formulation can combat deposits. Be sure to first run a couple bottles of AMSOIL Engine Flush (per sump size) so the unneeded acids are neutralized an purged from the crankcase.  The DME 15W-40 is a CI4+ oil. It’s still my best seller. Guaranteed to last up to 3X longer the OEM interval. Awesome for older cars which require high Zinc or ZDDP. I use it in my 1957 Studebaker.

Best Economy for Older Diesels
For the same 2006 and earlier who want the very best in fuel economy and choose to use a lighter viscosity as recommended by the manufacturer the 5W-30 Heavy Duty Diesel (HDD) 100% Synthetic is the best choice., Product code is (HDD).  I also use this one personally in vintage gas cars which need ha high zinc or ZDDP oil or gasoline engines that have a lot of deposits- this oil’s detergent package is superior to any! But if I had a pre 2007 diesel pick-up this would be my #1 choice. We sell a lot to older Durmax diesels and the Ford 7.3 owners in all climates.

Cost Conscious One Size Fits All (Original Equipment) & for Service Centers
For all diesel owners who are not doing extended intervals but want to use a premium AMSOIL product using the highest quality base-stock, this one is designed to compete on price. Choose the OED 15W-40 Diesel Oil. It meets CJ4 and is also back compatible for all CI4 and earlier specifications. For use in any year diesel new or old. Customers who are going to change oil at the OEM interval but want the  chose between the 15W-40 (OED) or 10W-30 (OEC) you now have a choice. Also popular to those who service diesel vehicles and want one product for all diesel service.

Tractors, Equipment and Fleets
Lastly our original 10W-30/SAE-30 Heavy Duty Diesel which is similar to the AME, High zinc (ZDDP) is generally the choice for work and construction turbo diesels or non-turbo tractors and equipment. Pre 2006 Diesel trucks wanting to use a 10W-30 would select this oil too. Generally the pick for all generators and skid steers as well. CI4 Diesel Specification or earlier.

European Car & Van
Many European diesels call for a diesel/gasoline oil based on specific specifications. For those please see the European Oil Line of products.
