Limiting Requirements For Engine Oils - Mitsubishi SS series Users Manual And Maintenance Manual

CAUTION
Avoid mixing oils with different brands. In most
cases, oils with different brands are not
compatible and, when mixed, they can seize
parts such as piston rings, cylinders, etc. and
cause wear to moving parts. It is best to stick
with the same brand and one type of oil at
successive service intervals.
