The Four Key Lubrication Tactics to Extend Diesel Engine Life

One of the benefits diesel engines offer over gasoline engines is longer service life. That being said, it's useful to know that there are steps you can take to get the maximum life from your engine before it needs its first overhaul. Here are some things you can do drawn from an article in Machinery Lubrication titled "Lubrication Tactics to Address Diesel Engine Life."

The article is essentially a practical outline of matters to address in answer to the question, “Are there any specific lubrication tactics that can help extend the service life (overhaul interval) of a diesel engine?”

The answer is yes, and the author proceeds to outline the four "rights" of lubricant application: 
The Right Lubricant
The Right Amount
The Right Component/Machine
The Right Change Interval.

It's a clever way to think about lubrication and it applies to all things that need lubrication, whether in the form of oil or grease. In this case we're talking about oils for diesel engines.

The first action suggested is to select a high-performance oil, rather than the one with the lowest price. This can be synthetic or mineral de[ending on the engine's requirements. 

Engines are designed to hold a specified oil level, so using the right amount of oil is important. This oil should not be mixed with other products, the author states. The specified oil is designed for a purpose. Its effectiveness can be altered through mixing with assembly lube or other products.

Because lubes age over time and during service life, they need to be replaced from time to time. This article notes that the "when" for changing oil should be not based on a time period or mileage limit. Rather, oil should be changed when it is ready to be changed.

To know the "when" you can perform oil analysis or utilize online sensors. This kind of monitoring will help you optimize the oil's use which still protecting the engine.

After explaining the four "rights" we are reminded of the need for proper filtration so that the oil is free of contamination, whether solid of liquid. The author suggests that the oil should be filtered before being put in the engine, and maintained in this condition using high-quality filters.

Many people use by-pass filters which take a portion of the oil out of circulation to continuously filter more slowly and more effectively before reintroducing to the oil stream. Premium air filters are also recommended because a majority of debris that gets into the oil is sucked in through the air.

Periodic oil analysis is the most effective way to monitor contaminants in the oil, whether fuel, glycol or soot, as well as other particulate matter. By this means you'll know when corrective actions need to be taken.

Because water contamination can be an issue in many machines the author recommends keeping your lubricants dry. They should also be kept cool, because the higher the operating temperature the shorter the lubricant life. For maximum service life, pay attention to operating temps.

If you're really looking for the most out of your engine life and lubricant performance, the article notes the importance of several additional variables: good training for your maintenance personnel, good procedures, the right tools, communication and team alignment. You may  even consider a pre-lube system. And last, but not least, use a high quality fuel and a periodic engine flush.

If it seems like a lot to consider, it's good to know what is possible.  This is the "white glove" treatment, if you know what I mean.  Read the original story here.
