The second number in an oil grade describes how the oil holds up hot — and a 110° day in traffic with the A/C blasting is as hot as your oil's life gets. Modern engines are built to tight tolerances around a specific grade; heavier is not better, it is just wrong. What matters in summer is level and freshness: hot thin oil punishes an engine running a quart low.
