Its good to stick with a oil you an afford. 10w30,10w40 are perfect for a Toyota 22RE. If you feel that you are looking for an extended protection while not harming your motor. I suggest adding a bottle of Lucas Motor Oil in place of a quart of reg oil in your oil changes. Been using Lucas in my Yota's for over ten years and it has proven to help extend the life and MPG. You can pick it up at any Auto Parts store.
Hope this helps....
