Narrative:

During climbout; we momentarily received engine oil warning on cap and engine oil light on engine number 2. Called for QRH; before first officer could get to QRH; both lights extinguished; but oil pressure was in the caution range; so we decided to do a precautionary landing and made an immediate landing to ZZZ. I elected not to shut the engine down since the engine oil warning on cap and engine oil light was illuminated for less than 2 seconds; and thought the safest course of action was to return for an immediate landing; since no other abnormal indication was present such as high itt; or high oil pressure or loss of torque.
