Non-Detergent Oils: Why Use Them?

Jennie McRae - Tuesday, November 18, 2014

When it comes to choosing the right oil for your engine, there are many things to consider. Not only do you have to think about the weight of your oil and the brand you should use, there is also the issue of whether or not you will use an oil with a detergent.


One of the benefits of using a main-line, conventional or synthetic oil is that there are detergents added to help keep your engine clean--they fight sludge and trap particles that would settle on the internal surfaces of your engine. Basically, the detergents suspend harmful particles in the oil until the oil is changed. Detergents can also assist in the deterring of oxidation and rust in your engine.


So, why would anyone ever not want to use an oil with a detergent?


Believe it or not, using a non-detergent may not be so bad for your engine! They still provide excellent lubrication and ensure that your engine will run at a cooler temperature. It is important to note, however, that oil analyses should be conducted regularly because non-detergent oils do not protect against sludge and contaminants. Your non-detergent oil will need to be changed at regular intervals in order for your engine to remain healthy and running efficiently.


There are also many applications where the use of a non-detergent is prevalent. Appliances that require gasoline, aquatic motors, and motorcycle engines often use non-detergents.
