Engine oil
In 4T engines, the engine oil is used to lubricate the distribution elements, the bench bearings and the
thermal group. An insufficient quantity of oil can cause serious damage to the engine.
In all 4T engines, the deterioration of the oil characteristics, or a certain consumption should be con-
sidered normal, especially if during the run-in period. Consumption levels in particular can be influenced
by the conditions of use (e.g.: oil consumption increases when driving at "full throttle".
