How to Tell If Motor Oil Is Detergent or Non-Detergent?
Oil refiners produce several grades or blends of lubricating oils for use in automotive engines. Some are detergent formulations, while others are non-detergent motor oils.
The basic difference is that detergent oils contain special additives which trap and hold dirt and engine deposits in suspension until the oil changed. Non-detergent oil lacks these additives. Distinguishing between the two types is an easy task that practically anyone can accomplish in a matter of minutes.
Visit an auto parts store or other retailer selling motor oil. Locate the motor oil display.

- Some are detergent formulations, while others are non-detergent motor oils.
Select several different brands of motor oil in the weight you wish to buy. As an example, you might select 1-quart containers of SAE (Socierty of Automotive Engineers) 30W, or 10W-30W.
Read the label on each container. Any motor oil which is non-detergent blend will be clearly marked as such. Conversely, any oil which is not specifically marked as non-detergent is by default, a detergent blend.
