Don't put synthetic in this bike. The gaskets and seals in the engine are 25 years old. If you put synthetic oil in it, it'll leak oil like a sieve. I don't think synthetic causes leaks, but it will find its way through places that regular oil won't, especially with old seals.
I had a '79 400 Hawk that I rode for years and just put regular oil in it. It's still running for the guy who bought it. The 450T will run great with regular oil.
Get a manual to change the oil. It's not hard to do, but these bikes don't have spin-on filters so the manual will give you some guidance the first time.
