Copper is one of the most interesting wear elements in my opinion as it requires more skill to interpret it's significance. Values in the thousands of ppm can be totally normal, yet a value of 50ppm can be a sign of serious component wear in the same machine.

This is not normally seen to the same extent with other wear metals, so what makes copper so special?

This is a common question I get asked and it's not as simple to answer as you might expect, but please keep with me.

Lubricating oil properties are derived from a combination of the base oil used and the additives used to enhance or remove certain desirable/undesirable characteristics. There are 5 groups of base oils – there are no good or bad groups and all the base oils have their purposes for different industries and applications. Groups 1 and 2 are mineral oils, and tend to be good solven...

Million pound or Million dollar decisions are often used as the proverbial phrase to denote the importance of a decision. However oil analysis reports can have huge ramifications to costs in the short and long term to clients and can save clients millions over time.

The largest fluid analysis decisions I have been involved in were in the >£100M+ category, but the nature of some of these topics is too sensitive to discuss on this blog. Therefore, I will discuss 3 smaller £1M decisions I had...
Making £1M decisions may be as simple as saying start or stop, but oil analysis makes sure it's the right one.

Machinery failure will cost you money, but with hydraulics that power so many every day pieces of equipment, failure can also cause accidents and loss of life. The reason is hydraulics are used to provide very precise but powerful movements. This is achieved by use of servo valves and other valve type devices to actively get oil to various parts of the machine to deliver power just when it is needed. If these become blocked by contamination or varnish then movements become jerky or uncontrolled....

High Temperatures, acids from sulphurous fuel & nitrogen air form strong acids when mixed with water from the combustion process making engines hostile environments.

TBN / Total Base Number (aka Base Number / BN) are usually calcium or magnesium based “antacid” tablets lube manufacturers put in the oil to neutralise acids protecting engines. Sounds good. However too much TBN can cause ash in the engine, so it is often a careful balance of choosing an oil with a TBN that’s right for yo...

Everyone knows keeping electricity flowing 24 hours a day, 365 days of the year is vital in keeping the nation safe. If the lights suddenly went out that may be an inconvenience for some, a loss of income to others and worse still result in loss of life saving equipment.

Despite advances in renewables, at time of writing over half all electricity in the UK still comes from burning fossil fuels, which in turn leads to rotation of steam or gas turbine blades that generate powerstaion electricity....

Why Oil Analysis Matters?

Oil Analysis is used by people just like you all over the world to reduce machinery downtime and improve equipment reliability. A small sample of oil from your machinery can provide as much information as a full machine strip down at a fraction of the cost and has been a proven technology for over 60 years to reduce forced shutdowns and failure repair costs. Want to understand how oil and grease analysis works and how it applies to you then watch this short video below.

How Much Can Oil Analysis Save Me?

Oil analysis is a brilliant tool that can save you money each time you sample. The returns on investment vary depending on your machinery type, so feel free to use our sister sites cost saving calculator at the bottom of their FAQ Page.

Get your oil tested

img 3041 Learn used oil analysis sample testing, lubrication reliability maintenance, predictive lab diagnostics to reduce costs & boost profits.If you have never had your oil tested before then what are you waiting for and get in contact with a lab today. There are many reputable labs all across the world that offer excellent oil analysis services you can use including our sister lab – Oil Analysis Laboratories, which is the only lab in the world to offer the LubeWear test. LubeWear identifies abnormal wear far earlier than traditional wear metal analysis techniques meaning you can catch faults earlier to keep your machine reliability at its highest. A brief video explanation of the rest can be viewed below.
