The sample was divided into two groups; a control group of buses using reference oils (SAE grade viscosities of 15W-40 and 10W-40) and a candidate group using LVO oils (SAE grade viscosities 5W-30). As kinematic viscosity at 100°C and High Temperature High Shear (HTHS) viscosity at 150°C have shown a good correlation with engine fuel consumption, an oil sampling program was implemented to study the possible variation of these oil parameters and its effect on the fleet fuel consumption during the test.
