Use what it is told in your owner's manuel 5w30. Synthetic or not is up to you, Before the swap I was using Quaker State Q Horsepower 5w30, worked pretty good to me.
But now I use synthetic Racing Valvoline 20w50, but this just because my engine is made for it... I mean oil clearances on the bearings and it helps keeping a little more compression with 13 PSI...
