The Importance of a Diesel Engine Oil Analysis

Investing in a diesel engine oil analysis kit is one of the smartest things you can do to ensure your truck’s oil health is still top-notch. These kits work for any diesel truck, ensuring you can monitor the engine health along with the condition of the lubricants. The kit will help identify any factors that may be detrimental to your engine’s lifespan or performance when used. The data provided by these kits show the underlying causes or symptoms of problems that may lead to reduced performance or complete failure.

Did you know that the source of most diesel engine issues and failure is contamination? The damage caused by contamination may occur because of a single root cause or due to a combination of factors that have resulted in wear and degradation on several levels. The main diesel engine oil contaminants that you need to continually monitor include glycol, fuel, water, and soot.

Glycol

Considerably one of the most significant threats to your engine, glycol has a high destructive potential in a very short amount of time. There are several ways that glycol may leak into your engine’s oil, and it can be blamed for almost half of all diesel engine failures.

Glycol will increase the viscosity of your oil, which hinders its ability to lubricate and cool the oil. It will also oxidize into acids, which reduces the TBN and causes corrosion. Also, if glycol contamination goes on, unnoticed, it can create the formation of sludge, which may plug the filters and cause abrasive surface erosion.

Fuel Dilution

This is another common issue for engines using rail injection, engines that contain DPF where post fuel injection is used, and HUEI type fuel injection systems. Moderate issues can result from excessive idling, frequent starts, and cold running conditions. If the problem becomes more severe, it is likely because of a leak, incomplete combustion time, or problems with the fuel injector.

Soot

Even though soot is to be expected with internal combustion engines, diesel engines are more susceptible to this due to incomplete fuel combustion. This can cause soot that begins to accumulate. While low levels of soot are no real reason for concern, frequent soot loading can cause several issues and engine failure.

Water

Believe it or not, water is bad news and often overlooked as a cause of diesel engine failure. Even though lower water levels are normal, if these levels increase, it can result in expensive downtime and costly repairs.

How an Oil Analysis Can Help

As you can see, several things can go wrong with your diesel engine. Oil analysis can help you determine the system’s overall health and let you know when you need to make repairs or invest in maintenance as needed. This simple kit can help you avoid the need to pay thousands of dollars to have your engine repaired, replaced, or rebuilt. Don’t overlook the importance of checking on the health of your diesel engine oil from time to time.
