What is a paraffin base oil pour point depressant?
Paraffinic base oil pour point depressants are additives that help reduce the pour point of paraffinic base oils. Pour point is the lowest temperature at which oil can flow or pour. Paraffin base oils tend to solidify at lower temperatures due to the presence of waxy paraffin molecules. Pour point depressant additives change the crystal… Read more

Is choosing a viscosity index the same as ISO?
ISO (International Organization for Standardization) is the standard that defines oil viscosity classifications. It provides a standardized grading system of lubricant viscosity called ISO VG (viscosity grade). Viscosity index (VI), on the other hand, is a measure of the change in oil viscosity with temperature. It quantifies the change in oil viscosity at different operating… Read more
