Oil Change on a 93 ES300

I don't own this car so I don't know much about them. How much oil do they take and what kind oil? It's a relatively high milage car, so I'm thinking of giving it synthetic. Should I use 10 or 5w30?

My question still stands and now I have one more.
Are there any write ups on changing the atf and filter on these cars?

You should use 5W30,stick with dino oil on a higher milage car,4 qts-4 cyl,5 qts 6 cyl,check on dipstick.Change trans fluid,clean filter 30,000.Hope this helps.
