Dynamic viscosity of motor oil
WebDownload scientific diagram Dynamic viscosity of the investigated 5W30 engine oil for different temperatures, pressures, and shear rates, as used in the simulation (from [31]). … WebThe SAE 30 oil is rated only for hot viscosity. This rating indicates how viscous the motor oil is at an operating temperature of 100 O C (212 O F). Why is this important? Temperature has a direct impact on viscosity. If an engine heats up beyond certain temperature thresholds, the motor oil will experience thermal breakdown and start to degrade.

WebThe numbers after the “XW” indicate viscosity at 100 degrees Celsius and represent the oil’s resistance to thinning at high temperatures. For instance, oil with a 5W-30 grade thickens less than oil with a 10W-30 grade in cold weather. Oil with a 5W-30 grade thins out more quickly at high temperatures as compared to oils with a 5W-40 grade.

WebDynamic viscosity is a measure of the viscous forces and is a function of gas composition and static temperature. As viscosity has only a second-order effect on an engine cycle, total temperature may be used up to a Mach number of 0.6. The effect of fuel air ratio (gas composition) is negligible for practical purposes.
