5W40 is generally better for summer because it provides better protection during startups and can perform more efficiently at higher temperatures. 10W40 is also a good option, especially if you live in very hot climates as it offers slightly thicker and more stable viscosity at extreme temperatures. However, both oils are suitable; the best choice depends on your vehicle's specifications and the environmental conditions you expect.
