How Centrifugal Oil Separators Enhance Engine Performance

Lubrication oil is the lifeblood of any engine – without it, the engine simply wouldn't work. It lubricates the components while keeping the engine cool, resulting in smooth operation and a reduced risk of breakdowns. 


But lubrication oil can also turn out to be a double-edged sword. Dirty oil can wreak havoc on the engine's inner workings, causing blockages, wear, and even total breakdowns. Luckily, there's a way to prevent this: centrifugal oil separators


The IOW Group is at the forefront of centrifugal filtration technology. In the guide below, we'll discuss how dirty lubrication oil can harm an engine, how centrifugal oil separators can help, and which separator stands out as the top choice.


How can dirty lubrication oil damage an engine? 


Over time, engines start to degrade as friction causes microscopic particles from the engine’s surface to chip off, and the combustion of fuel produces soot. When lube oil passes through, it picks up and moves these harmful contaminants throughout the engine before depositing into a sump. Standard oil filters installed will catch most of the larger particles, but smaller, more abrasive particles will still pass through under pressure and into the engine. 


This can be detrimental to the overall health of the engine, as abrasive materials wear down key components much faster and can contribute to engine failure. The addition of heating and cooling engine oil also has its issues – it physically changes the molecular structure over time, causing them to fuse and build up into harmful particles.


So, how does this affect engine performance?


In simple terms, dirty, sludgy oil makes for a less efficient engine. When an engine is not operating efficiently, the performance of the engine reduces, increasing fuel consumption and emissions. 


Contaminated oil is thicker, making it less effective at cooling your engine and putting extra strain on its many parts, which can make your engine run less smoothly. This also leads to blockages that stop your engine from running optimally. To mitigate this, regular oil and filter changes are recommended - putting this off can lead to big (and expensive) issues! 


Why do engines need centrifugal oil separators?


Centrifugal oil separators are by far the most effective tool in filtering engine oil. By using centrifugal force, centrifuges separate microscopic particulates from the oil, keeping it clean and free-flowing. The cleaned oil can continue to do its job efficiently, keeping the engine cool and removing contaminants. This is a much better and more cost-effective cycle, as key components and standard filters last longer, reducing the need for regular changes. With the smooth running of engines, less friction is observed and so fuel consumption is kept to a minimum, limiting overall emissions. 


IOW Group MP Centrifuges are the superior choice for achieving a high-performing engine 


The unique features developed by engineers at IOW Group guarantee more particulates are removed from lubrication oil, extending oil change intervals as well as the lifespan of standard full-flow filters. IOW Group provides the perfect filtration solution to ensure day-to-day operation is as smooth as possible. 


IOW Group achieve this through:


  • Higher revolutions per minute (RPM) - the higher the RPM, the greater the centrifugal force and therefore separation capabilities. 


  • Disc stack technology - greater surface area within the separation chamber removes even more particulates. 


  • Fully sealed - both the top and bottom of centrifuges are sealed with O-rings, preventing cross-contamination of clean and dirty oil. 


  • Distributor impeller - reduces the risk of backpressure, cross contamination and increases centrifugal force and separation. 


  • Remote monitoring as standard - monitor the performance from your mobile device. Check on how fast the centrifuge is spinning or when it needs a service.

Keeping engines running efficiently takes more than regular oil changes and the occasional filter swap. The real cost of engine maintenance often hides in plain sight. Small particles build up, oil quality declines, and engine components begin to wear faster than they should. It all leads to more downtime, higher costs, and avoidable repairs. Centrifugal oil separators offer a smarter and proven alternative. These simple, robust devices clean your oil more effectively and help your engine run better for longer. No fuss, no gimmicks, just quality engineering that saves time and money.
