around 60,000 miles? The actual type of car would be helpful, smart guy.

Some engines are designed to run with 10W30. When temperature gets cold, 10W30 gets too think and have problem starting the car. So it is recommended that you would run 5W30 in the winter and 10W30 for summer.
Other cars running 5W30 as standard oil, you really don't need to change to 10W30, unless for some reason you would want to run thicker oil (such as leaking engine seal, thicker oil means slower leak)

If your motor does not use (not leak) more than a quart in 3,000 miles the answer is never. 5W-30 cools engine parts more efficiently. The oil pump drives easier using less horsepower.
Most importantly, oil is pumped to critical engine parts quicker at start-up where 90% of engine wear occurs.

10/30 is thicker oil. I would use in hot weather.

In an older, high mileage car in the warmer months.

you would switch to the other when you do not have the other available. but switch back as soon as possible.
