Do not mix oil of different brands together.
Oils of different brands are mostly not com-
patible with each other. If they are mixed,
the mixtures can cause components such
as piston rings, cylinders etc. to seize up
and cause wear to moving parts. The best
thing is to keep to one brand and one type
of lubricating oil for each subsequent serv-
ice.
