Narrative:
While in cruise we had the left engine oil light illuminate indicating low oil pressure. The oil pressure gauge confirmed the low oil pressure. Following our checklists we shut down the left engine. We requested to change our destination to ZZZ. On about a 10 mile final we realized the airspace was extremely busy and we [advised ATC] in the hope of avoiding the need for a diversion or go-around. We landed at ZZZ without incident. After landing we discovered that the left oil filler/dipstick cap had developed a gap in the o-ring allowing the engine oil to escape. When the o-ring was replaced and the oil replenished; the engine ran fine.
