It is shown that very real gasoline economies can be realized with multigrade lubricants and that these savings are very appreciable for average automobile passenger car trip; gasoline savings appear to have minimum value of 3% even for very long trips with fully warmed up engines; oils used were 5W-20 and 10W-30 and two medium VI, SAE 20 and 30 grade oils, with viscosity indices of 53.
