In our last blog we discussed the differences between 'environmentally friendly', 'inherently biodegradable', and 'readily biodegradable' lubricants. But what are 'Environmentally Acceptable Lubricants'?   Environmentally Acceptable Lubricants Environmentally Acceptable Lubricants (EALs) are a special class of biodegradable lubricants. These lubricants meet the criteria set by the Environmental Protection Agency (EPA). This designation is to ensure that consumers know exactly what specifications are met when they are purchasing an EAL product.…

When searching for lubricants that are good for the environment you wouldn't be alone if you're confused about the way they are named. Today in the lubricant market you will see oils that are "environmentally-friendly", "inherently biodegradable", and "readily biodegradable". Is there a difference between these names? Absolutely.   Conventional Oils Standard mineral hydraulic oil is made with a base oil that typically contains zinc. Zinc is used as an…

Can you use the same lubricants in the summer as you do in the winter?  This question comes up frequently in our industry, and the answer is simple. It depends! What does it depend on?  Everything from application, to specific equipment, to operating conditions, to OEM requirements, and location of the equipment. If you use your equipment during extreme cold weather you may find that your hydraulics are sluggish or…

Your engine oils are available as conventional, synthetic blend, or full synthetic. These categories are based on quality. But what is really the difference between them?   The Difference is in the Base Oils The most common difference is the type of base oil used in the blending process. The American Petroleum Institute (API) classifies base oils into five major groups. These groups are based on the level of saturates,…

Zinc has been a key additive in hydraulic oils for decades. Its primary purpose as an additive is as an anti-wear agent.  The zinc forms a sacrificial layer in the form of Zinc Dialkydthiophosphate (ZDDP). ZDDP protects pumps and other parts of the system from wear damage during boundary lubrication instances.   The advantage to hydraulic oils with ZDDP is that it will also work as an antioxidant - extending…
