I think what convinced me to keep synthetic in ours was this page:

That, and other pictures of messed-up 2.7s convinced me. Our '04 should have been "fixed" so it shouldn't be a problem (yours should be too), but I sure feel a lot better running it.

Spec for ours is 10W-30, and I'm told that the oil pump is clearanced for the thinner oils only; running a thicker oil can cause early pump death. Newer oils with low zinc should be fine in this OHC engine.

Good luck, is sure a fun motor to drive behind.
