Oil Analysis

What is Oil Analysis?

Oil Analysis (OA) is the process of testing contamination levels and the chemical make-up of oils (and also fuels and other fluids), in laboratory conditions, in order to identify; their properties and any contamination or wear debris that have been introduced from machinery.

The purpose of Oil Analysis is to accurately determine the condition of the oil and its machinery, in order to make necessary adjustments, to prolong the life span of both oil and machinery, keeping machines running at an optimal level for longer. As such, our Oil Analysis service is always followed up by a comprehensive report of the findings and advisory notes.

Comparing the results of Oil Analysis samples over the life span of machinery, allows negative trends to be identified and corrected, helping to eliminate costly repairs.

The Importance of Oil Analysis

Whatever your industry, as an operator or owner of equipment that utilises any type of fluid - be it engine oil, hydraulic oil, gear oil, transmission oil, grease or coolant - you should know that these fluids are the lifeblood of your equipment.

The oils protect and lubricate, reduce friction, clean vital parts, act as a coolant, maintain compression, lubricate seals, operate in high-pressure systems or where hydraulic parts are used and to maintain the life of the components.

The grease is present to lubricate and stop wear occurring in bearings, pins and bushes and to ensure that all the components run smoothly and with minimum friction.

The coolants are there to keep the equipment from overheating and to protect metals from distorting under extreme temperatures.

Contamination causes over 85% of mechanical failures resulting in expensive repairs and costly machine downtime.

Each moving part in an oil lubricated circuit has a normal wear rate. As these parts wear they introduce particles into the oil, generally these are very small but through an oil sampling and analysis programme these can be monitored. If there is an increase in the amount or size of the particles the analysis will highlight these and help to pinpoint the source. This gives you the opportunity to take preventative action before a failure can occur.

Many machine manufacturers analyse and test their products over many years and millions of miles to failure point. During these tests regular oil samples are taken and a complete analysis over the lifespan of the components is built up. This is then broken down into a wear analysis record. This trend is then used by the oil laboratories to be able to monitor the machinery.

Regular oil analysis is a low cost preventative maintenance tool that enables owners/operators to see what is happening inside the machinery.

Benefits of Oil Analysis & Sampling

There are many benefits to implementing an oil analysis programme. It allows you to:

Reduce Operating Costs

Reduce the costs of oil and filter changes, by keeping your oil cleaner for longer.

Pinpoint Potential Problems

Detailed analysis will help identify any problems in their infancy.

Plan Manpower and Maintenance Schedules

Regular analysis will highlight trends allowing you to plan system services.

Plan Service Schedules

Kniw when you need to change, or clean your oil to plan the service work.

Maintain Productivity

Keep your equipment running as smoothly and efficiently as possible.

Save Downtime Costs

Analysis and filtration keeps your machines operational for longer.

Reduce Major Repairs

Identify minor repairs to prevent them from becoming major repairs.

Reduce Waste Products

Analysis ususally shows that your used oil can be recycled and re-used.

Prepare Equipment for Sale

Evaluate the state of equipment in readiness for purchase or sale.

Oil Analysis Sampling Tips

Oil Sample
Labelling
Mike's Tip

Always attempt to supply as much information about the oil as as possible to the laboratory; The more information provided, the better - hours on meter, miles, oil changed date, machine history, oil added and more. Try to also provide a sample of new oil or the details of the product.

Taking a
Sample
Andy's Tip

Always sample your oil at normal running temperatures and where it has not been possible to do so, please indicate that it has been "taken cold" on the sample form. Only sample the oil after a minimum of 15 minutes of normal running, to ensure the oil is well mixed.

Health &
Safety
Gary's Tip

Oils can reach temperatures of 200°f (93°C) particularly in engines so always use protective gear such as gloves and goggles. Oil spillage can be dangerous so keep to hand an oil spill kit in case of an emergency.

Sampling
Points
Peter's Tip

Where possible install oil sampling points on all machinery. This reduces the risk of contamination and maintains consistency in oil sampling. These points are inexpensive and simple to install. Many machinery manufacturers fit these as standard.

New Oil
Samples
Mike's Tip

If you change your oil supplier, provide the laboratory with the relevant information and a test sample of the product. Provide the type, brand and classification of the oil.

Sample
Tubing
Andy's Tip

Always use a fresh tube for each sample to avoid cross contamination. Cut the tubing into the correct length ensuring it does NOT touch the bottom of the reservoir.

Vacuum
Pump
Peter's Tip

Make sure the pump is clean after each sample is taken, draw off ¾ of the bottle and discard into a suitable container, then take the sample into a fresh bottle.

Hygienic
& Clean
Gary's Tip

Oil is an irritant and contributes to several medical skin conditions e.g. Dermatitis, eczema. Maintain a strict health and safety policy when handling oil based products. Dispose of all contaminated materials safely and in accordance to government guidelines.

Don't
Contaminate
Andy's Tip

When taking oil samples do not take samples from used oil filters, drain plugs or a waste oil container.

Coolant
Samples
Andy's Tip

Use a separate sampling pump for coolants as glycol will give a false reading to oil samples.

Oil Analysis Recommendations

Please consider the following when it comes to Oil Analysis:

  • Always refer to the machinery manufacturers recommendations for oil types; using the wrong oil type could invalidate a warranty claim.
  • Use an independent laboratory for oil analysis as they are not there to sell you oil and will give you unbiased reports.
  • Oil analysis can reveal the amount of wear taking place on your machinery and the location, by the type of metal accumulation in the oil.
  • Regular oil sampling will allow you to build a trend based on hours/miles and enables maintenance staff to plan their schedules.
  • Sulphuric acid contamination is caused from excessive amounts of sulphur in diesel fuel combined with water contamination.
  • Additional filtration can remove contamination and water, prolonging the life of the oil.
  • Oil analysis reports will identify when to change oil and oil filters, making it easy to maintain your equipment.
  • Change air filters regularly and fit a pre-air cleaner to prolong air filter life.
  • Train maintenance staff in correct oil sampling procedures.
  • Always sample oil hot.
  • Always sample oil from the same point.
