engine oil for 02 tribute v6

hi, I am a new owner of 2002 tribute V6. just changed my engine oil to Castrol Edge 5w-30, just want to know which one is the best, Mobile 1?

I prefer full synthetic, either Mobil 1, or Castrol.  Any of the regular brands (mobil, castrol, valvoline, penzoil) will be equally good.  If you want to take the next step up from those...buy Redline or Royal Purple.  However, in a street car, I think thats overkill. 
Also, my owners manual recomends 5-20...not sure if your weather/use conditions would necessitate 5-30 or whatnot, but check your owners manual, and use what they recomend.

many thanks, I checked the manual and it said 5w-20 which I could not find, the two available are castrol 5w-30 or mobile 10w-30, I am planning to use mobile 10w-30 next time.
