Engine oil consumption
I n ord er to provide effective lubri cation and
cooling of int ern al eng ine compo nents, all in­
t e rnal combu stion engines use a ce rtain amount
of oil. Oil co nsumpti on varies from en gi ne

gine and may change significantly over the life of
th e e ngine. T ypicall y engin es whi ch have a
break -in period, us e mor e oi l during the break ­
