Testing Confirms When To Extend Recommended Drain Intervals


As engine oil manufacturers continue to develop new products designed to be stronger and last longer, some also are recommending drain intervals. Original equipment manufacturers also specify drain intervals and qualify oils for use in the equipment they sell. In both instances, it is important to recognize these recommendations may not be all inclusive of every operating condition or every application in which the oil might be used. For more information and clarification, please contact one of our data analysts.

How do you know an oil manufacturer’s recommended intervals will protect your equipment? Will the oil last as long as they say it will in your operating conditions? Could it last longer?
Yes, no or maybe! Only testing in-service fluids can answer that question. Combining the manufacturer’s specifications with laboratory results and recommendations from certified data analysts is the best way to safely optimize drain intervals, minimize wear and preserve equipment health.

What tests are needed to safely extend drain intervals?
An Advanced Mobil test package is required to safely extend drain intervals. This test package examines the three main fluid properties – base number (BN), oxidation/nitration and viscosity – that assess the oil properties responsible for protecting equipment. Tracking the values of these tests will alert you when a fluid is no longer capable of performing as expected until the next oil sample or drain.

Are there maintenance practices that will help me extend drain intervals?
When extending drains, the most important maintenance activities are to replenish depleted fluid properties, continue changing filters and monitor contamination/wear levels. If possible, replenish depleted additives or sweeten with new oil as needed. Filters are vital to capturing contaminants, so continue changing oil filters if it doesn’t require draining the sump. Finally, make sure to continue oil analysis testing at the old drain interval in order to monitor contamination levels to determine if the extended exposure to contaminants harms the equipment.

New EZ Label is Available


We’ve been listening.

“This form is too complicated.”
“Do I really need to provide all this info?”
“There has to be an easier way to submit samples.”

Based on the customer feedback we’ve received over the years, we have improved our sample labels to make it quicker, easier and simpler to submit sample information, which reduces the likelihood of errors. You can request the new label be sent with your next sample jar order.

During the process of redesigning our sample information forms, much research was conducted internally and externally to thoroughly understand:

  • how customers complete the sample forms
  • how samples are packaged and shipped to us
  • how samples and paperwork are cleaned when fluid leaks during transit
  • how sample details are entered into our systems

We also tapped into our customers to serve as beta testers and confirmed the new label really does make it quicker and easier to submit samples.

The new label includes detailed HORIZON® instructions to simplify adding or updating equipment and submitting sample information online. This allowed us to simplify the required information on the form and reduce the paper size. In addition, the sample jar label features a coating to improve its resistance to absorbing oil.

Customers may or may not have access to the Internet all the time, so we left a very simple component and sample information form on the label. If a paper copy needs to be sent in with the sample, the form can be detached from the label and easily wrapped around the sample jar.

The label’s new features could benefit all our customers, so I encourage everyone to make the switch and reap the benefits. You can view the new label and how to fill it out by downloading our instructions. When you’re ready to try the EZ Label at one or more of your locations, contact our Customer Service team at custserv@eoilreports.com or 877.808.3750.

Setting Limits on Fluid Properties


Earlier this month, I talked about how we set limits for wear metals and contaminants. There is one final group of results Data Analysts examine to determine the health of oil, fuels, and coolants: fluid properties.

Fluid properties are the physical and chemical features that allow the fluid to perform as it was designed. Viscosity, Acid Number, Base Number, Oxidation, Nitration and Additives are the main fluid properties examined by fluid analysis.

These properties don’t have much in common. Different tests are used to determine if the fluid still has the ability to protect equipment. Viscosity needs to be run at different temperatures to match the operating conditions of the equipment, ICP is used to quantify the metals found in common additives, oxidation and nitration are measured using FTIR, and acid number and base number need to be run using different titration methods to get the measurement we desire.

Just like wear metals and contaminants, the actual flagging limits depend on what the fluid is, the equipment the fluid is being used in, and what application the equipment is doing. These factors all can change the maintenance recommendations from the Data Analysts, which is why it is important to provide as much information about the sample as possible.

To learn more about the challenges facing each fluid property and how we set our flagging limits, please download this technical bulletin.

Monitoring Oil to Extend Drains

The livelihood of truck owner-operators hinges on the dependability of their equipment. When they experience a catastrophic equipment failure, it takes a long time to recover.

Expensive repair and replacement costs are just the tip of the iceberg. Towing, equipment rental, fees on the late shipment and a damaged reputation could come packaged with the breakdown.

Oil, Coolant and Fuel Contamination


It doesn’t matter if it came from outside the equipment, was generated inside the equipment or if it worked its way into the oil from another system in the machine, contamination is any substance that isn’t supposed to be in the fluid being tested.

Most people think of contamination as something working its way into the equipment from the outside. Water and many types of particles, like dirt, sneak in through cracks, broken seals or unprotected ports, but in equipment with physical and chemical reaction occurring inside of it, foreign substances are only part of what we consider “contamination”.

Some contaminates are created during equipment operations. Soot is a natural byproduct of diesel combustion and commonly works its way into the engine oil, which is why the oil is formulated with additives to deal with soot. Lubricant additives are designed to protect components and prolong oil life; however they can become contaminants when heat, pressure or a chemical reaction causes them to fall out of suspension.

Fluids from other systems can be contaminants, such as coolant and fuel mixing with engine oil. All three systems need to operate in conjunction with the others, and leaks happen. Small holes and cracks between the oil and cooling systems could leak fluid one-way, so testing both fluids is recommended to catch leaks early. Over-fueling or worn cylinder rings can lead to fuel entering crankcase oil. Either way, cross-contamination from other systems is a sign of a mechanical problem that needs to be fixed before it escalates into a breakdown.

The type of equipment and application will determine what contamination could affect it and what tests to perform. The Contamination Flagging Limits technical bulletin has more information on how POLARIS Laboratories® determines the severity of contamination.

Setting Wear Metal Flagging Limits


Our customers have a wide range of knowledge about fluid analysis. Many are new to the process and others have decades of experience. Some have even earned tribology certifications or degrees. Our Data Analysts end up talking to all of them, so we receive a wide variety of questions every day.

Occasionally, our experienced customers compare our test results to the wear metals flagging limits set by the original equipment manufacturers (OEMs) and we often get calls asking why we don’t follow the OEM’s recommended levels. Fortunately, this is an opportunity for us to explain the value of analysis from POLARIS Laboratories®.

We have analyzed millions of oil samples on most types of equipment, meaning we have a huge pool of data and customer feedback. We use that information to make sure our flagging limits won’t have customers perform maintenance too early or too late. Giving precise recommendations saves customers time, money, and effort, but we want to make sure that equipment is protected, too.

In addition to evaluating individual wear metals, the combinations of wear metals are also significant. Combinations of wear metals are significant because they may indicate a particular alloy, which is vital to understanding if a specific part is wearing – for example, elevated copper and tin would indicate a bronze part is wearing.

Many OEMs publish wear metal guidelines. These general guidelines may be a place to start to understanding fluid analysis reports, however they are not designed to be used as absolute values. To maximize the value of fluid analysis, a customer should expect a credible laboratory to have a comprehensive database, utilize statistical analysis to refine flagging limits, and have qualified Data Analysts to make appropriate maintenance and reliability recommendations.

How We Set Flagging Limits


In the Data Analysis department, one of our key responsibilities is to answer any questions customers have about fluid analysis. A lot of our calls are about what results mean. Does the fluid need to be changed? What could be causing that strange noise? We also get questions asking for testing recommendations for a specific application or issue being seen. However, the hardest questions to answer are about our flagging limits. The only easy answer for these questions is: “It’s complicated…”

Our process for defining flagging limits is actually something that we are quite proud of. It can be difficult to provide our limits because they are very dynamic and specific to the information provided about the equipment, fluid, and application. For example, one engine in your fleet may have different flagging limits than another because our limits are customized based on the specific equipment manufacturers and models. Limits are also affected by the rate of change from prior samples. Individual severities may change based on other results that are flagged. These are just a few scenarios that affect limits, but I think you can begin to understand some of the complexities surrounding our limits.

We’d like to clear up some of the confusion by publishing a series of articles to address the more common questions surrounding flagging and alarm limits. What aspects of your report flagging have you been curious about? Post your questions in the comments section of this blog so we have an opportunity to reply and use your questions to guide the topics of our articles.

Establishing Goals

Recently I visited a mine that was interested in setting up a new account with POLARIS Laboratories®. One of the first questions I asked was, “What are the goals of your program?” I can’t say I was overly surprised when there was a moment of silence and pondering. While many of us realize there are benefits in performing fluid analysis, and know we want to be involved in a program, we seldom consider all the potential capabilities that a program can offer.

So why is establishing goals important? When many of us first started using fluid analysis, especially in mining, our goal was to simply monitor the health of the components and do what we could to prevent a catastrophic failure from occurring. After all, who wants to lose a core on a $300,000 engine and have an unplanned unscheduled service event happen? No one looks forward to explaining these events to upper management.

Today’s oil analysis capabilities offer a great deal more than just monitoring component health. With today’s technology and performing the proper test, we can monitor the condition of the oil, see if it is suitable for continued use, reduce the amount of used oil disposal, adjust our maintenance intervals and strategies, adjust component replacement schedules, improve forecasting and budgeting and increase component life hours. We have not even begun to touch on other benefits, such as coolant and fuel testing.

However, accomplishing these goals may require additional testing, which costs more. Can you afford not to?

I would like for you to consider a recent case study conducted by POLARIS Laboratories®. Customers who were actively involved in their fluid analysis program realized a 25:1 return on investment – for every dollar spent on fluid analysis their return was 25 dollars! In many of the studies, specific to mining, the return was as high as 40:1!

Have you considered the cost savings if you could double your oil drain intervals? The savings go way beyond the cost of the oil. Think about the savings in maintenance man-hours, the increase in equipment availability and utilization, the reduction in waste disposal. What would be your savings if you could increase component life hours by just 50 percent or prevent that next catastrophic failure from occurring?

Goals, my friends, are so very important to establish. If you do not establish these goals upfront and do not have the appropriate testing set up to match these goals, your program will never reach its full potential. If goals and testing do not match, one of two things are going to happen: You are paying for testing that you do not need, or the very test you are paying for will not help you meet your goals. Goals change, and therefore your testing may need to change with it. Even if you have an established, mature testing program in place, today may be the day to take another look and ensure the testing you are paying for is everything you want it to be.

If you need assistance setting realistic, achievable goals for you oil analysis program, feel free to contact us to get moving in the right direction.

Experience Yields Proven Results


Have you ever faced a moment in your fluid analysis program where you needed expert help to solve a problem? It can be hard to find someone with up-to-date, firsthand knowledge of both your industry and the equipment you are using. Thankfully, POLARIS Laboratories® can help.

For more than 30 years, my career was in heavy equipment maintenance and maintenance management. I have been using oil analysis since 1983; however, it was not until I was employed in the mining industry that I really gained the appreciation of the many benefits that a quality oil analysis program could offer, including some I simply was not familiar with before.

I’ve worked at all levels: The mechanic that pulled the samples, the maintenance planner that reviewed the results, the QA/QC coordinator that looked for improvements, the business improvement team leader and as a member of a global mining heavy equipment users group that developed best practices and policies. I like to think during that time I developed a true understanding of fluid analysis from hands-on all the way up to the strategic level.

Just like all of the members of our Field Services Team, I combine my “customer” experience with my understanding of POLARIS Laboratories® various tests and capabilities to recommend a test combination to best match the customer’s goals. Whether it’s over the phone, in a conference call, or at one of our private trainings, you can rest assured that we have your best interest in mind, both as your fluid analysis provider and as someone who used to turn wrenches and wade through a pile of reports.

This mixture of experiences, I believe, has allowed me to gain a unique perspective of managing a quality fluid analysis program, and this new career path has given me a greater insight into the world of fluid analysis. I have now had the opportunity to see and work with the laboratory and gain new perspectives and I am excited for the opportunity to share this with you.

Fluid Analysis Is Greener than You Think


We should all be aware of the impact we as humans have on the environment and want to protect our vital resources for future generations. The world population continues to grow, and for growth to be sustainable we must use less virgin products and capture more what we use for reuse. This is one of the reasons why I’m proud of the impact POLARIS Laboratories® has on the environment.

The fluid analysis industry helps our customers conserve natural resources. We provide customers with information about the remaining useful life of the fluids so they can use their lubricants and antifreeze to the fullest. These extended drain intervals allow the customers to go much farther than the manufactures’ recommendations in some cases. This saves the energy, raw materials and pollutants needed to produce new fluids and reduces millions of gallons of used oil and coolant needed to be disposed of.

In addition, the testing extends the life of the equipment itself. By taking action on the recommendations made by our data analysts, our customers prevent wear and reduce the chances of catastrophic breakdown. They get more miles traveled, hours of productivity and tons moved from their equipment than without our maintenance recommendations. Simply put, engines, transmissions and hydraulic systems last longer. The amount of steel and other metals no longer needed to make replacement equipment is staggering.

While POLARIS Laboratories® helps the environment through our customers; we also do our best to reduce the environmental impact of the testing we perform. We use solvents, plastic, glass and cardboard during the fluid analysis process, as well as the fluids sent in for testing. These items can harm the environment if not handled properly, so we have set up procedures to handle and dispose of these products responsibly. Nearly everything we use can be recycled.
