The below list is a general guide for additive concentrations in lubricating oils. This list is not definitive and with the recent emergence of Nano-technology and ashless additives that are not metal based the variation between different additive packages formulations will change greatly. The best way to confirm the additive element concentration for your lubricating oil is to send an unused sample for reference to the lab, or contact your lubricant supplier for details. Additive concentrations...

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....

Water In Oil – the problem

Water is a very poor lubricant and the fact it does not mix easily with oil means it causes double the problem by removing the stuff that is. The density of water means it will drop to the bottom of bearings or loaded surfaces, the exact place the best Lubrication is needed. Water with air also promotes corrosion (rust) within the system. In addition, high temperatures environments and high loading water will boil off at the mating surfaces, leading to a temporary l...

Normally before a big trip we tend to do more of the checks we should be doing on our car all year round such as confirming the tire pressures, topping up the screenwash and checking the coolant level.

This is because the impact on breaking down on our way to the supermarket is not seen as big a problem as breaking down hundreds of miles away from home. Breakdown cover is often a comfort blanket to most, but unless it specifically says in your policy you are covered abroad most policies do no...

If you look at the running costs of your machinery or fleet of vehicles there are some usual suspects that are the big costs for your business. One of these is fuel. It is so widely known as a major cost of running any engine that it is the major focus of all machinery manufacturers and even the smallest progression steps in efficiency are marketed heavily to the end users.

Look at the next car advert you see, I bet somewhere in the advert will be a mention of the vehicles efficiency for fuel...

This article will answer the following questions:


What is a Total Acid Number (TAN) and what is a Total base number (TBN)?



When to change engine oil and what indicates an oil is spent?




Acid Number – This is the concentration of acid in the fluid. The new oil value may not be zero since some oil additives react similar to acids with the reagents used for testing. Hence it is important to monitor the trend in change of TAN from a baseline sample or new oil reference. In...

For as long as insurance companies have existed they have been looking at new and innovative ways to determine risks of a claim when setting insurance rates. In recent years this has even extended to apps on your mobile devices to track your car driving habits.

For decades now, insurers have been using oil and fuel analysis to confirm the validity of claims. This can be confirming actions arising from oil analysis have been implemented, but also, from larger claims, has involved insurers collec...

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.
