The 5000 is if you drive regularly on the freeway for 20 miles or more, and you never hit traffic and you never dive in the city. So unles you do that 3000 is the best bet. As far as the oil type goes, if the manual says 5w20 use 5w20. I don´t car if the 5w30 is syntetic or not, 30 viscocity is 30 viscosity. That oil will not flow as well as the 5w20 through the passages and bearings.

Explain to me how thicker oil would let your engine run smoother? If anything it will make you run slower due to extra strain on your engine to pump the thicker oil. Not to mention eat into your gas milage.

^^^ If you have ever drove an older car that was beat up you would understand. It helps knock, ticks, pings and if you burn lots of oil then if you put thicker stuff in you wont burn as much.
