| 1 | Colors Meters normally measure from 0 (no color) to 8 (black) | |||||||||||
| 2 | The Viscosity Index – The relationship between Viscosity and Temperature is described by the Viscosity Index (VI) – the higher the VI of an Oil the lesser it’s viscosity varies with the increase or decrease in temperature | |||||||||||
| 3 | If VI VI is above 80 base oil is HVI grade if below 80 but above 50 base oils are MVI | |||||||||||
