I would use a synthetic oil with 5w-20. Usually synthetic protects just as much as the next highest step up of organic oil while giving you the benifits of a lower viscocity such as increased gas milage.

My brothers toyota had same amount of engine noise at idle as mine. And when he put in amsoil high performance oil. He said his car never has idled smoother. All the sound went away. And it feels like the car has more power on the freeway. It could all be in his head but i can say it does idle very smooth and its quite as a mouse on idle. I am very anxiouse to do the same to my car soon as the engine is broken in in a few more miles.
