ISO VG 150, SAE 40 | Non-Detergent Oil


Non-detergent oils are free of detergent additives that can pose a problem to engines and machinery operating without a filtering system built to eject floating debris. Detergent additives loosen sludge and buildup, but without a filtration system, can cause slowed performance and even systems failure. These oils are designed for machinery such as compressors which benefit from detergent-free lubricants. Also, these oils may be applicable for some antique automobile engines - check with OEM specifications and product data sheets.

SAE 40W oil has a minimum high-temperature kinematic viscosity of 12.5 mm2/s (cSt). This number refers to the standard testing mechanisms used to determine how much resistance to flow (i.e. viscosity) these oils demonstrate.
