aution
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 pis-
ton 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 service.
