what oil to use

can you guys tell me which engine oil you use i wanted to get some feedback on what to put next to my car right now i have a syntetic castrol 10 w 30 is there better ones and whats the difference (give me some brands please) I have noticed big difference between regular and a syntetic

Every one that I know runs Mobil 1 synthetic

I use Mobil 1 10w-30 with the M1-201 filter (longer than stock filter)

Next oil change i'm switching over to mobil 1 synthetic 5w-30 and a K&N oil filter. Right now i'm using 5w-30 quaker state. Also I see that AMS oil in the advertising above, i'm not sure about that, you might want to look into that stuff.

Also i've read your signature Ripn12s and I was wondering, how does the reflective overlays work, and do you have an example picture? Also where would one go about getting some. ;)

I've got the reflective black "pontiac" on the rear bumber, during the day you cant tell any difference, but when headlights hit "pontiac" reflects silver. Also a black/red reflective arrowhead on the front.
