HOW well are multigrade oils performing at low temperatures?An investigation has shown that the low-tem perature properties of mulrigrade oils are often not equivalent to the single-grade oils-lOW in a mulrigrade oil may actually be 20W.One phase of this investigation, a full-scale cranking study using commercial 10W and 10W-30 oils in cars at 0 F, is discussed in detail in this paper.HOW well are multigrade oils performing at low temperatures?An investigation has shown that the low-tem perature properties of mulrigrade oils are often not equivalent to the single-grade oils-lOW in a mulrigrade oil may actually be 20W.One phase of this investigation, a full-scale cranking study using commercial 10W and 10W-30 oils in cars at 0 F, is discussed in detail in this paper.
