5 w 30 would be ok I dont know of any cars using the 5w20. the 20 is a litte thin for when the engine warms up. I recommend.... to read your manual and use what the manufacturer recommends. Alot of people think that weird combos of different oils are better, but I assure you they are not. I also recommend Synthetic Oil like Mobil 1 and use a HIGH quality filter and extend your oil change intervals to around 5000-7500 miles for highway use
