Hai steemian friend
how are you all hopefully in good health.
replace the oil so as not to jam the machine and others, oil change is estimated 6 months but this rule can not be applied to all cars, because each rider uses and treats it differently.
The quality of the used vehicle oil also affects the period of oil usage, the oil brand used by MEDITRAN SC about 5 liters for L-300 freight cars,
used oil, pour into a container that can be closed.
