Why lubricant analysis supports engine health




To keep your vehicle working smoothly and safely, you must ensure your engine oils and coolants are maintained properly. As part of your routine vehicle maintenance and management, lubricant oil analysis is a critical process that is performed to check the condition of your vehicle’s lubricants and detect any possible problems with your engine’s health.  

Total UK’s lab-honed lubricant oil analysis service is TOTAL ANAC. TOTAL ANAC provides a thorough evaluation and diagnosis of engine oil health, while improving the performance of your vehicle and lengthening your machine’s lifetime. But why is oil analysis important? Why does it support engine health? 


Why is lubricant analysis important?

One of the most important aspects of vehicle ownership is preventative maintenance. To keep your machine working at its very best, lubricant oil analysis allows you to monitor and plan corrective actions.  

Oil lubricant analysis, and the information it provides, is extremely important because improper engine lubrication can result in major failures and inefficiency. Using comparative oil sample results, lubricant oil analysis identifies any abnormalities to help you avoid breakdowns and reduce your operation costs.  

Lubricant analysis also identifies when you need to replace components, reveals how your engine is wearing, and supports you to keep your vehicle in optimal shape.  


What can lubricant analysis identify?

Lubricant oil analysis can provide significant information such as:  

  • How worn the engine’s components are 

  • Whether the lubricant is contaminated  

  • Characteristics of the lubricant, such as its viscosity 

  • Additives and elements present in the oil 

  • The engine’s level of wear compared to other identical engines. 

How does your oil become contaminated?

Engine oil can become contaminated by elements such as water, fuel, dust, soot, and coolant. These contaminants can reduce your engine’s overall effectiveness and degrade your oil in various ways. Lubricant analysis can be used to identify the presence of these contaminants before they permanently impact your vehicle’s engine health.  

For instance, if your oil becomes contaminated by water, your engine is at risk of corrosion. In addition, your oil may become sludge-like in consistency and immobilize your vehicle’s oil circulation and distribution.  

If dust infiltrates your engine, it can scratch the internal metal and produce coarse particles that can irreversibly damage your internal systems. Lubricant analysis can indicate that you need to change your air filter and oil.  

For diesel engines, incomplete fuel combustion can produce soot. Soot will thicken your engine oil and cause blockages, and lead to the premature deterioration of your engine parts.  

Similarly, fuel dilution can occur if your fuel injectors leak or when fuel is not fully burned during the combustion process. This thins the oil and disables its ability to withstand heavy speeds or loads, and the resulting lack of viscosity also means there is greater friction between surfaces, causing rapid wear on engine components.  


Why do you need to check and analyse your coolant? 

Coolant is a critical part of the engine system and remains in your engine for a long period of time. Unfortunately, metals can become present within your engine coolant and this can cause coolant failure. This can result in your engine overheating and, ultimately, cause engine failure.  

Coolant effectiveness and concentration will deteriorate over time and coolant PH needs to be monitored closely. The colour of coolant can clearly identify whether it needs to be replaced or analysed further. If the coolant is too acidic it may become corrosive, however, alkalinity may also disrupt the fluid’s ability to neutralise acids and prevent damage.  

Lubricant oil analysis can quickly identify coolant PH levels, concentration levels, and metal contamination. Often, lubricant oil analysis can also identify the cause of the impurity, which means solutions can be swiftly implemented.
