How do I properly break in my new Toyota Supra engine?

I just purchased a brand new Toyota Supra and I want to make sure I properly break in the engine for optimal performance. I've heard conflicting information, can someone give me concrete steps to follow?

It's important to follow the manufacturer's recommended break-in procedure, which is usually outlined in the owner's manual. Typically, this involves driving at varying speeds and avoiding hard acceleration for the first few hundred miles. Make sure to also change the oil and filter within the first 1000 miles.

Some people suggest using synthetic oil for the first few thousand miles to help with the break-in process. While this may offer some benefits, it's important to note that using synthetic oil too early can cause premature engine wear. Stick with conventional oil for the first few thousand miles.

It's also important to avoid revving the engine too high during the break-in period. This may be tempting, especially with a high-performance car like the Supra, but it can cause excessive wear and tear on the engine. Take it easy and gradually increase your speed over time.
