How it's used
Literally describing the physical inability of oil to mix with water, this expression is used metaphorically to describe people or ideas that are fundamentally incompatible. It carries a strong sense of permanent opposition where no compromise is possible. You will often hear it used when discussing personality clashes or conflicting business strategies.
Examples
Their personalities are like oil and water, how can they be friends?
