Technical Oil light

[Silvasportin23]

My oil light flickers on for maybe half a second when i'm on the motorway, but when i check my oil it's showing as full. Can anyone help please??

it actually refers to oil pressure not how much oil you have.
i'd try a new oil pressure switch for what they cost.
