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....

Foam in a lubricated system can be a real problem. That is because foam is a poor lubricant and can cause significant wear within a lubricated system if the lubricant film is replaced with foam. However, most foam people talk about in lubricated systems is cosmetic foam. This is foam that can spill over the side of machines during operation and although there is a slip hazard from the oil spilling over, most of this foam never reaches the parts of the system where it could cause damage. This is ...

Extreme Pressure (EP) is the most common anti-wear additive for high load gears. It is Sulphur-Phosphorus based and used when other additives such as ZDDP are not sufficient to give high load wear protection.

If you have ever changed a gear oil, the distinctive smell is from EP.

In normal conditions EP is inactive, but at high temperatures at loaded surfaces EP reacts to form a metal sulphide toughened coating to protect against wear.

However with copper based components care must be taken as...

This article will answer the following questions:


Why does soot not settle out in an engine oil?


What is a Total Base Number?


Why is there calcium in my engine oil?


Is my engine oil alkali or acidic?



The answer is they both contain Calcium. Now before you start considering whether it is best to go for a semi–skimmed or fully–skimmed on your next car service, or start pouring a 15W40 on your breakfast cereal I must remind you that is where the similarities end and this arti...

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...

I was asked recently by a client why does the lab not test viscosity at 100'C when there is a high water contamination. The client was quite concerned as he had quoted his client a test suite including viscosity and was concerned he may have to refund the client. This should never be the case as the suites are always assuming the sample is suitable for the tests requested e.g. I have had clients ask for a ppm water value on samples that are 90% water and sediment contents on bags of sand neither...

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.
