Oil performs many important functions and appropriate lubrication can improve efficiency and dramatically extend the useful life of your equipment. At the same time it is at risk from a variety of factors, such as environmental or process contamination, harsh operational parameters, system design and human error.

Oil analysis can be used to maximise oil performance, minimise or eliminate adverse factors and at the same time predict developing faults before catastrophic failure occurs.

As part of a proactive Condition Based Maintenance programme Oil Testing/Oil Analysis can deliver significant savings and a substantial return on investment.

We serve a wide customer base both within the UK and overseas. Industries covered include oil & gas, transport (haulage/rail/marine), energy and utilities, manufacturing, including both major OEMs and component suppliers, building services, maintenance services, agriculture, chemicals, steelworks, renewables, mechanical equipment and vehicle dealers and fleet operators, garages and many others. We are also able to assist individuals looking to test oil or fuel from their own vehicles and other machinery.
