    Abstract: <p>The present study contains investigation of the viscosity of different selected motors oils. The
viscosity of the selected motors oils has been studied at different temperatures. We studied the behaviour of
those oils using rotating viscometer. It was found that the viscosity decreases with increasing temperature. The
present study has studying the activation energy for the motors oils. It was found that the activation energy
for the best oil less than the others oils.</p>
