Case Studies Show Benefit of On-Site Oil Analysis

On-site oil analysis pays off for fleet maintenance

Fleets use on-site oil analysis to reduce downtime and save money. This article highlights several different fleets including a municipal utilities fleet, a sheriff's fleet, a sanitation fleet and a city fleet, and how oil analysis benefits their maintenance activities. One of the biggest costs for the municipal utilities fleet was the labor cost associated with performing the oil changes. Safely extending oil change intervals saved them enough money to pay off the cost of the on-site oil analysis equipment in two years.  

For the sheriff's fleet, the biggest cost was the cost of having law enforcement officers not out on the road doing their jobs. Bringing a vehicle in for an oil change often required paying officers overtime and took away from their more important activities. Extending oil change intervals saved on this cost.

Spectro Scientific's Third Edition Of The Oil Analysis Handbook

It has been over two years since the publication of the first edition of Spectro Scientific’s In-Service Oil Analysis Handbook. Our goal was to compile a comprehensive reference book of common in-service oil analysis techniques to help readers understand and choose the right technique and instrumentation for their needs.

Fast, accurate total ferrous measurement

Posted by Augustus Kaskons on November 15, 2016

The measurement and trending of abnormal ferrous wear debris in machinery lubrication oils is arguably the most significant indicator of machinery health and a key predictor of catastrophic machinery failure. There are several methods available to measure the ferrous content of lubrication oil.

Guide to Measuring Biofuel Blending

Posted by Augustus Kaskons on October 07, 2016

As the global commitment to renewable energy sources grows, the importance of using biodiesel as a blending component with diesel fuel has increased. Biodiesel consists of fatty acid methyl esters (FAME) which are produced by the transesterification of certain feedstock oils, such as soy, rapeseed, canola, and others. The biodiesel is then blended with diesel fuel at amounts required by the regulatory agencies of different countries. It is important for fuel terminals and distributors, as well as regulatory agencies, to check the concentration of biodiesel in the diesel fuel in order to make sure it is within these allowable limits. Diesel fuel with too little biodiesel will not meet renewable fuel standards and fuel with too much biodiesel may cause engine failures.

Techniques for Soot in Oil Analysis

Posted by Augustus Kaskons on September 30, 2016


Since no engine is 100% efficient, products other than carbon dioxide and water will be formed during combustion. One such product produced from incomplete combustion is soot. Soot is a mass of mainly carbon particles that are typically spherical in shape. As soot levels rise, the soot particles begin to clump together and become more dangerous. The soot levels will continue to increase and the particles clump together until it reaches a level great enough to precipitate out of the oil. This precipitation will both increase the viscosity of the oil and attach itself to the engine surfaces which will significantly increase wear on the engine. This precipitation can also lead to filter plugging. Performing regular soot checks can realize cost savings by extending drain periods, reducing used oil disposal, and extending the life of diesel engines.

Techniques for Oil in Water Analysis

Posted by Augustus Kaskons on September 23, 2016

 

The people responsible for conducting oil in water measurements understand that the measurement can be quite challenging. Wastewater from different sources can contain many different types of hydrocarbons, each with different chemical make-ups. On top of the lack of chemical uniformity in different oils, there has been a large variety of methods developed to quantify the oil in the wastewater. While none of the following methods is perfect, each will have its own advantages and disadvantages for oil in water analysis.Oil in water analysis is a global issue that crosses many industries, analytical methods, and regulatory agencies. Due to the negative effects of oil on the environment, there are strict limits on the amounts of oil allowed in water. Failure to meet these limits can lead to heavy fines. While any industry that discharges produced water needs to test for oil in water, their specific needs can differ from industry to industry. The petroleum industry is most concerned with measuring Total Oils and Grease (TOG) in both their upstream and downstream wastewater. For industrial pretreatment of wastewater, public water treatment plants, and most other nonpetroleum industries discharging produced water, it is most important to test for Fats, Oils and Grease (FOG) in their effluent. FOG differs from TOG in that it tends to contain large amounts of animal and vegetable components in the oil. FOG can be especially concerning in effluent streams because it can lead to clogged sewer lines which causes Sanitary Sewer Overflows (SSOs).

Guide for Measuring Fuel Dilution in Lubricating Oil

Posted by Augustus Kaskons on September 16, 2016


Fuel dilution in oil can cause serious engine damage. High levels of fuel (>2%) in a lubricant can result in decreased viscosity, oil degradation, loss of dispersancy, and loss of oxidation stability. Fuel dilution is one of the most important lubricant failure modes in internal combustion engines. It usually occurs due to improper fuel-to-air ratio. Fuel dilution can also occur due to excessive idling, piston ring wear, or defective injectors and loose connectors.

Measuring Oil Chemistry: Nitration, Oxidation, and Sulfation

Posted by Augustus Kaskons on September 09, 2016

An in-service lubricant encounters air, heat, pressure, corrosive agents, and other factors that cause chemical changes in the oil. A change in oil chemistry can affect the ability of the lubricant to do its job (for example if crucial additives have been depleted). Over time, these chemical reactions can result in build-up of harmful degradation by-products like weak organic acids. Oil chemistry analysis always includes oxidation and may also include nitration and sulfation depending on the application. In some cases, oils may also be tested to check for the depletion of specific additives, like a ZDDP antiwear package.

Using Spectroscopy for Used Oil Analysis

Posted by Augustus Kaskons on September 02, 2016

Evaluating the wear condition of equipment is a primary requirement of condition monitoring programs. Oil wetted equipment will generate wear particles throughout its lifetime, the nature and rate of the wear varies from initial break in through to end of life seizure. The technique employed to detect wear and its severity is spectroscopy. Spectroscopy is a technique for detecting and quantifying the presence of elements in a material. Spectroscopy utilizes the fact that each element has a unique atomic structure. When subjected to the addition of energy, each element emits light of specific wavelengths, or colors. Since no two elements have the same pattern of spectral lines, the elements can be differentiated. The intensity of the emitted light is proportional to the quantity of the element present in the sample allowing the concentration of that element to be determined. Typically these techniques get their names from the method used to excite the elements.
