Normal oil consumption occurs due to the combustion of small quantities of oil in the cylinders, due to the removal of combustion products and particles resulting from friction. In addition, oil is consumed due to the high temperatures and high pressures to which it is subjected in the engine.
Furthermore, oil consumption is affected by operating conditions, driving style, and manufacturing tolerances. Oil consumption should not exceed 10 l/1000 km. Oil must be added when the "Add" mark is reached.
Caution: Add only a little oil at a time. If you add too much oil on vehicles with a catalytic converter, drain the excess oil, otherwise unburned oil will get into the muffler and destroy the catalytic converter.
