How do I properly maintain the engine of my Toyota Supra?

I recently purchased a Toyota Supra and while I love its performance, I am not sure how to properly maintain the engine. What are some important maintenance steps I should take and how often should I do them?

Regularly check and change your oil to keep the engine running smoothly. This should be done every 5,000-7,500 miles.

Don't forget to also check and replace your air filter every 15,000 miles to ensure proper air flow.

It's important to keep an eye on your coolant levels as well, and top off if needed. This should be done every 30,000 miles.

Regularly checking and replacing spark plugs can also improve engine performance and should be done every 60,000 miles.

If you notice any unusual noises or performance issues, take your Toyota Supra to a trusted mechanic for a diagnostic check.
