Graph oil viscosity

Compare our motor oils. Filter by vehicle type, formulation, Mobil brand or viscosity to find the right oil for your vehicle. You can also see customer ratings and

This figure correctly displays for these correlations, that increasing solution gas oil ratio reduces bubble point oil viscosity and also the greatest oil viscosity  With high viscosity too much power is required to shear the oil film, and the flow of oil through the engine is retarded. Viscosity tends to decrease as temperature   While the descriptions may seem similar, there are important distinctions between the two. Figure 1. Capillary Tube Viscometer.

The main requirements for an engine oil are defined temperature-viscosity properties, protection against wear and corrosion, keeping the engine clean, holding particles like soot or abrasives in suspension, yield strength under compression and many more. Temperature impacts the flow properties of engine oil. Engine oil is available in different SAE grades to suit the climate where it is used and the purpose of the user.
